REBUILDING PLANS IN MEXICO1
Introduction
In Mexico, the direct users of the fishery resources include people from different
social sectors such as the fishing cooperatives which members are locally called
“cooperativist fishers” (“Pescadores cooperativados”); the private sector, with groups
called “permisionarios”; the “armadores”, or simply “iniciativa privada”, which are
groups of private entrepreneurs with interests in fishing who, most often, possess fishing
vessels and have some investment in the processing sector; and the “pescadores libres” or
“free fishers”. The first two sectors hold fishing permits whereas the latter sectors pursue
fishing without any fishing permit and thereby pursue illegal commercial fishing.
The cooperatives (from any productive sector, including fisheries), are social
enterprises: all its assets (e.g. cars, processing plants, if any, among others) are common
property of the members. The highest authority of a cooperative is the general assembly
of members. A second, lower level of authority are two councils, an Administrative
Council, which is in charge of marketing the harvested product, and the Security Council
which is in charge of the enforcement of rules. According to most cooperative’s internal
rules, these authorities have a mandate of at last two years. Membership in cooperatives is
voluntary. Each member has only one vote in decision making at general assembly
gatherings. Some cooperatives run their own processing plants (e.g., in the abalone
fishery, where there are several such plants). Each member of a cooperative shall,
according to the internal rules, deliver all his or her catch to the cooperative for
marketing. In order to become a member of a cooperative, a person should submit an
application to the general assembly which then decides on whether the applicant is
accepted or not. Except for emerging and potential fisheries (i.e. some underdeveloped
fisheries, e.g. some crab fisheries in the Ocean Pacific coast) new entries to most fishing
cooperatives are currently restricted. The reason for restricting acces is that fishers are
well aware of the fact that admitting more fishers in a cooperative means less catch for
each member.
With respect to the legal status of a cooperative, there are no special laws for
regulating the cooperatives. On the other hand, “pescadores libres” or free fishers have
diverse backgrounds. In some cases they are sons of members of fishing cooperatives
who were not accepted as new members at their father’s cooperative but who pursue
fishing without a fishing permit; or simply fishers that care not to belong to a social
enterprise like a cooperative. Also there are many “pescadores libres” who moved from
sectors experiencing economic crises (mostly from agriculture) that turned to fishing for
their livelihood. Overall, “pescadores libres” usually means “illegal fishers” but in several

Moisés Valencia Arámburo, and Francisco Arreguín Sánchez.

cases, entitled fishers fish alongside those illegal fishers in the same fishing areas.
However, should any fisher be pursuing fishing only for subsistence purposes, the current
Mexican Law on Fisheries allows him/her to do so which means that the current
legislation does not limit or restrict the total number of subsistence fishers to fisheries that
have not been previously allocated to someone else.
This paper will presents four Mexican case studies that do have implemented either
fishery rebuilding plans or isolated management strategies that can be considered to be
first steps towards development of a rebuilding plan.
Methods
This work was carried out in two stages. During the first one, a contract between
ECOSUR and OECD was signed at the end of November 2009 which contained the terms
of reference (TOR’s) with detailed instructions on the consultant’s task, together with the
schedule of an agreed upon remuneration. The second stage started with a selection of
four Mexican case studies to be included in the project, a task that was completed by the
consultant together with the co-authors as a research team, in collaboration with the
OECD Secretariat.
To fill out the “ATTACHMENT: Fisheries Rebuilding Plans- Case Study” template
of the present project, two sources of data were used; firstly, a literature review of
published and unpublished papers, and secondly, the expertise of a research team -the co-
authors, who gathered during the end of January 2010 to discuss and agree upon the
scope of the project as well as on the contents that were needed to fill out at each section
of the “attachment” template. With respect to the former, they included: unpublished
Master and Doctor of Science Theses, articles published in peer reviewed journals,
official documents published by the government, such as the National Fisheries Charter
(NFC), the National Fishing Institute’s (Instituto Nacional de Pesca, INAPESCA) Red
Book (i.e., INAPESCA, 2006), the Normas Oficiales Mexicanas (NOM`s), the Annual
Fishery Statistics (“Anuarios Estadísticos de Pesca”), a paper from OECD (OCDE, 2006)
as well as several internal (unpublished) stock assessment reports available at the
INAPESCA and National Institute of Aquaculture and Fisheries (Comisión Nacional de
Acuacultura y Pesca, CONAPESCA) websites . In this regard, this Mexican project is
based primarily based on past research undertaken by several authors. Thus, in several
cases, it was noted that in some of the reviewed papers concepts were used loosely and
which blurred the meaning of some details. Taking this into consideration, the co-authors
did their best in responding to the comments and questions of clarification posed by the
OECD staff to earlier drafts of those case studies. However, due to the nature of the
project, not all questions could be fully covered.
Finally, data to this paper also includes personal communications with staff from
INAPESCA (Mexico City) as well as from the Fisheries Secretariat of the Yucatan state
and from several fishing cooperatives from Quintana Roo.
Results
Results on the proposed Mexican case studies
A first Mexican case studies’ list was sent to OECD, which is shown in the following
paragraph. Some of those fisheries have already implemented a fishery recovery plan,
while others are fisheries with isolated management strategies which although sometimes
REBUILDING PLANS IN MEXICO – 3
REBUILDING FISHERIES © OECD 2012
could be taken as stock recovery strategies, but are in need of a formal, explicit stock
recovery plan. Fisheries with relevance in terms of both, economic and social aspects are
marked with an *:
* The abalone fishery (Haliotis fulgens, H. corrugata, H. cracherodii, H. sorenseni and
H. rufescens). This is a small-scale fishery located on the western coast of the Baja
California Peninsula. It is one of the few cases of deteriorated fisheries which has a
fishery recovery plan. This plan was proposed in 1996 and fully implemented in the
year 2000. It is considered a successful case of a recovered fishery. There is political
will to recover this fishery.
* The totoaba (Totoaba macdonaldi) fishery. The totoaba is an endemic species
harnessed by small-scale and semi-industrial fisheries. It is located at the Gulf of
California, particularly at its inner side. In 1943, the catch reached a peak of about 2,000
tonnes but had fallen to only 50 tonnes in 1975. Since then the Mexican government
imposed a moratorium and introduced several aquaculture projects to enhance the stock.
However it is known that, an illegal and unreported catch for this species has continued
for several decades albeit the moratorium. Currently, juveniles of this species are
captured as by-catch in the shrimp fishery with estimated fishing mortalities
representing about 90-95% (Cisneros-Mata et al., 1995). This species is currently
enlisted on CITES, more specifically on the IUCN Red List of Threatened Species (as
critically endangered) and also on the Mexican NOM-059 (as endangered species)
(DOF, 2002, p. 77).
*The red grouper (Epinephelus morio, Epinephelus spp. and Mycteroperca spp.)
fishery. The target species of this fishery is the red grouper (E. morio). This is a
sequential fishery located at the Yucatan Peninsula, with a coastal fleet (or “flota
menor”) a semi-industrial fleet (or “flota mayor”) and a foreign industrial fleet (a Cuban
fishingvessels). It is currently overexploited (DOF, 2004).
*The queen conch (Strombus gigas) fishery. This is a small-scale fishery with strong
linkages to the culture and traditions of provincial fishers and is used as a sign at the
flag of Quintana Roo state. Situated in the greater Caribbean, the stocks of this species
have been systematically depleted in many fishing areas and the only place in Mexico
where its fishing is permitted is in the state of Quintana Roo. In order to assign the TAC
for this species, the Natinonal Fisheries Institute (INAPESCA) has estimated the stock
size using spatial models.
*The pink shrimp (Farfantepenaeus duorarum) fishery. This is an industrial fishery.
According to Arreguín-Sánchez et al. (2008) this fishery’s yields peaked at about
27,000 tonnes per year in the early 1970s, of which the pink shrimp represented around
90%. At present, with a fleet of about 300 boats, it yields around 3000 tonnes per year,
and pink shrimp contributes less than 1000 t of the total.
The jewfish (Epinephelus itajara) fishery: in the Gulf of Mexico and at the Quintana
Roo’s coast, this species is a part of a multispecies artisanal fishery based on bony
fishes called “escama” (or scaled fish). Due to this species longevity (about 40 years)
and behaviour it is very easy to capture it and therefore its abundance has been
diminishing in several fishing areas. The National Fisheries Chart states that it is
necessary to recover the population of this species at the Quintana Roo’s coast,
particularly at Chetumal Bay (DOF, 2004, p. 440).

*The pen shell (Pinna rugosa) fishery: This is an artisanal fishery located in the Pacific
Ocean, particularly off the Northwestern coast of Mexico and specifically on the coasts
of Sinaloa and Nayarit. During the last 5 years, there was a “boom” in this fishery
because of the discovery of a new fishing bank. Unfortunately, due to both natural
events and mismanagement, to date, the new bank has been already
depleted.Additionally, from 2005 to 2007, 14 fishers have died pursuing this fisheries
due to diving-related accidents. Currentfield observations claim that there are between
1900 to 2600 “pescadores libres” or free fishers (i.e., people without a fishing permit)
taking part in this fishery.
Mullets fisheries: white mullet (Mugil curema) and flathead mullet (M. cephalus).
There are two fisheries where the stocks of these species are perceived as deteriorated.
Those fisheries are located, respectively, at the Northwestern coast of Mexico (Pacific
Ocean) and in the Gulf of Mexico (DOF, 2004, p. 151).
The marsh clams (Rangia cuneata and R. flexuosa) fishery: This former artisanal
fishery was located at the Gulf of Mexico, particularly at the Campeche coast.
Currently, there is a permanent closed season because those populations are recovering
from overfishing. (DOF, 2004, p.129).
The brown sea cucumber (Isostichopus fuscus) fishery (see DOF, 2004, p. 483).
During the 1980’s and early 1990’s, there was a sea cucumber fishery which collapsed
and was permanently closed from May, 1994, to March, 2000. This fishery is currently
located at the Eastern coast of the Baja California Peninsula. It is currently exploited by
fishing cooperatives under a productive (area-delimited) system called UMAS
(“Unidades de Manejo para la vida Silvestre” or Units for Wildlife Management).
Based on a coordinated work with OECD Secretariat, the selected Mexican case
studies were cases numbered as 1, 3, 4 and 5, on which detailed information are presented
in the following paragraphs.
The Abalone Fishery
General Information
Five species of abalone form the resource base of a small-scale fishery located on the
western coast of the Baja California Peninsula (Figure 9.1). The fleet which takes part in
this fishery is composed of around 900 boats with outboard motors. The capture of these
species is undertaken through SCUBA and “Hooka”, collecting the specimens by hand,
with the aid of a palette knife, which size and characteristics are currently under
regulation.
The abalone muscle is used for human consumption and its shell is used for
handcrafts. Although this fishery started at the end of the 19th century, it was by the mid
20th century when its catch peaked at 6,000 tonnes of muscle. However current abalone
catches range only around 350 to 400 tonnes.
Among various management tools and regulations, the management of this fishery
encompasses fishing cooperatives as the de facto users of the abalone resource to which
the Mexican government grants fishing licenses (“concesión” in Spanish). The
management authorities has delineated four fishing zones in which catch quotas are
estimated annually to each abalone species by area.

Figure 9.1. Geographical distribution of the abalone fishery (in red) from Mexico
Every year, the amount of catch quotas are discussed and negotiated between the
government (INAPESCA and CONAPESCA) and the cooperatives. The management
measures also include minimum size restrictions and closed seasons by geographical
areas as well as a common will to strengthen surveillance in order to eradicate illegal
fishing (DOF, 2004). Furthermore, the National Fisheries Charter (NFC), portraits this
fishery as deteriorated and has set as a management objective to maintain the annual
biomass to a half of its virgin biomass (DOF, 2004). This fishery is primarily based upon
two species, the green abalone (Haliotis fulgens) and the pink abalone (H. corrugata),
which together represent over 95% of the total catch. Catch statistics by species show that
the deterioration of this fishery is primarily due to the green abalone’s gradually
diminishing abundance.
Species
The resource base includes; pink abalone (Haliotis corrugate), green abalone (Haliotis
fulgens), black abalone (Haliotis cracherodii), white abalone (Haliotis Sorensen) and red
abalone (Haliotis rufescens).
Fishing Area(s)
The fishery takes place at the western coast of the Baja California peninsula, from the
United States border., southward to a zone called “Arroyo El Conejo” in the state of Baja
California Sur (Figure 1). Nevertheless, the most productive area of the fishery is located
between the 24ºN and 28ºN, and between 111.5ºW and 115.5ºW. The five species of
abalone can be found at the following depths; the pink abalone between 7 and 44 m (with
a higher abundance between 8 and 28 m), the green abalone between 1 to 24 m (with a
higher abundance between 1.5 and 9 m), the black abalone between 1 and 8 m (with a
higher abundance between 1 and 4 m), the white abalone between 10 and 50 m (with a
higher abundance between 24 and 29 m) and the red abalone between 6 and 18 m.

Timeframe for rebuilding plan
Several documents issued by the government, such as the National Fisheries Charter
(NFC) (DOF, 2004, p. 79) mention a recovery plan for this species. The term used is
“plan de recuperación” which translates as recovery plan but also uses the term
“programa para la recuperación del recurso” which translates as program for the recovery
of the fishing resource. A second document, the Red Book (INP, 2000, p.150;
INAPESCA, 2006, p.28) mentions a recovery strategy for this fishery using the term
“estrategia de recuperación” that is, recovery strategy. However, no documentation was
found which formally mentions a rebuilding fishery plan. However we acknowledge that
there is a set of strategies clearly devised to recover this fishery (or “restaurar” as stated
in the Mexican Fishing Law). Therefore, in the following paragraphs, this project on
Mexican fisheries analyzes and evaluates the experiences from this set of strategies.
The set of strategies found did not contain a predefined timeframe to reach a specific
fishery recovery target. Overall, this set of established strategies is based upon an
initiative designed and implemented by the government, specifically by the INAPESCA
and the CONAPESCA, with an active participation of the fishing cooperatives. This
initiative is based on the rationale of controlling the annual catch of abalone, from one
year to the next, aiming at maintaining the stock biomass at a level which maximizes its
yield.
Major identified sources of mortality/threats to rebuilding
The recovery strategy for the abalone stocks is fully based on controlling the fishing
effort. This means that the fishing mortality is considered to be the main cause of
abalones’ diminishing catches and the main main threat to the stock. However, some
climatic events, such as the ENSO, have had negative impacts on the size of these stocks.
In this regard, it has been found that the ENSO events have had a negative influence on
the abundance, and even that during some years, have produced a complete disappearance
of the macroalgae, Macrocystis pirifera (Gluyas Millán, 2000), which is the main diet of
abalone, resulting in low recruitment for abalone. Several scholars consider this cause of
mortality as one of the major threats to the recovery of these stocks. Moreover, there are
several predators which also cause natural mortality on abalone, particularly the fish
Scorpaenichtys marmoratus and starfish, Pycnopodia helianthoides, along with Pisaster
ochrecea.
A different cause of natural mortality in abalone is an illness (in Spanish “Síndrome
de Deshidratación” (SD)) which causes a considerable loss of weight on the specimens,
usually causing death. This illness has primarily benn detected in the black abalone but
there is evidence that other abalone species (the green, pink, white and red abalones),
have also been affected. Finally, according to Bórquez-Reyes et al. (2009), this fishery
does have two groups of resource users, the cooperativist fishers but also the free or
independent fishers. The latter group of fisheries operate without a fishing license (and
therefore practices illegal fishing) and sell their harvest at the abalone black market in
$400 pesos per kg (about 23.5 Euros). Hence, pursuing illegal fishing on abalone catches
double the price set by the cooperatives (at $200 pesos per kg). Overall, this high abalone
black market’s price, together with both poor fishery surveillance by the CONAPESCA
and the easiness of which free fishermen pursuing this illegal fishing, is another threat to
the rebuilding of these stocks (Bórquez-Reyes et al., 2009; see also DOF, 2004, p. 80).

Rebuilding goal/target (MSY, MEY etc.)
The National Fisheries Charter states that, in the long run, the management objective
of the abalone fishery is to maintain its stocks at the half of its virgin biomass (= B0 /2)
(see DOF, 2004, p. 79). The estimation of B0 was obtained (exclusively to green abalone,
Haliotis fulgens ) through a logistic (rBt (1-Bt / Bo)), surplus yield model using
maximum likelihood procedures (INAPESCA, 2006, pp.17-18) in which B0 =1068
(Sierra, 2004, p.34).
Although the calculation of the catch quotas started in 1990, in practice, several
adjustments have been undertaken by the INAPESCA to the annual stock assessments.
However, there is only one issue that has been maintained without any change, namely
the negotiations of the catch quotas -which since they started have been agreed upon by
the government and the cooperatives. In general, the rationale of setting a catch quota is
to select a quota which, while the fishery operates at acceptable economic levels, as
assessed by the involved parties themselves allows a gradual steady recovery of the stock
biomass. Thus, for practical purposes, there is no Target Reference Point but the
assessment of the annual biomass is simply compared against the one estimated the
previous year. Hence, the decision rule in setting the catch quota proceeds as follows: a)
decrease the catch quota, as compared to the one set the previous year (if there was no
positive growth but a decrement in stock biomass); b) maintain the same catch quota of
the previous year (if the stock biomass showed neither an increment or a decrement, or c)
increase the catch quota as compared to the one set last year (if a growth in stock biomass
was detected).
Overview of issues (e.g. factors that led to development of rebuilding plan;
confounding factors such as multi species fisheries, ecosystem issues such as
climate change fisheries)
As the abalone is a highly valued resource, the gradual diminishing of the abalone
catch, from 6000 tonnes in the 1950s to less than 0.5 tonnes during the 1990’s, motivated
the devising and implementation of a stock recovery strategy starting in 1990, adjusted in
1996-97, and followed until the present. As an example of the past stock assessment
undertaken for one of the abalone species, the pink abalone, it was estimated that the size
of its stock, as it was from the early 1990’s, then it would take approximately between 25
and 45 years to recover to the size of its Maximum Sustainable Yield (MSY) as it was
during the 1960’s. This estimation assumed that fishing mortality is the main cause of
mortality. However, it is also known that the ENSO events do cause massive mortality of
the macroalgae Macrocystis pirifera, the main diet of abalone. Such mortality was
detected by Gluyas Millán (2000) during the ENSO event of 1997-98. This author
reported that abalone were completely uncovered of macroalgae according to biological
surveys. Thus, it seems that, the interaction of the fishing mortality with the ENSO
impacts does have an impact on the success of a fishery recovery strategy based solely on
controlling the fishing mortality.
Institutional Framework
Legislation – Authority (brief description)
In Mexico, the legislation which regulates the access, use and management of fishery
resources is the “Ley General de Acuacultura y Pesca Sustentable” (LGAPS, or the
General Law on Sustainable Fishing and Aquaculture). The authority responsible of the
8 – REBUILDING PLANS IN MEXICO
REBUILDING FISHERIES © OECD 2012
application of this legislation is a Secretariat called as SAGARPA (or “Secretaría de
Agricultura, Ganadería, Pesca y Alimentación”); to this end, two administrative bodies of
SAGARPA, the INAPESCA (“Instituto Nacional de Acuacultura y Pesca”), and the
CONAPESCA (“Comisión Nacional de Pesca y Acuacultura”) undertake several duties
and enforce the regulations, as stated by the Law. The SAGARPA Secretariat is in charge
of coordinating and leading the scientific and technical research on fishing and
aquaculture but also in devising and updating the National Fisheries Charter (NFC) a
management instrument for the fishing and aquaculture resources of Mexico. In
particular, the Article 33 of the Law states that the NFC shall contain the guidelines,
strategies and other previsions for the conservation, protection, restoration and use of the
fishing resources. Therefore, the term “restauración” (in Spanish) would be the closest
(and only) term, used in Mexican legislation as a synonym to “rebuilding” as used at the
OECD. Furthermore, no Mexican documents issued by the government or the by
Mexican fishery scientists use the equivalent translation of the term “rebuilding”, which
literally would be “reconstrucción” in Spanish; rather they use “recuperación” which
translates into English as “recovery”.
To assist in management, the Mexican government also devised an instrument called
Normas Oficiales Mexicanas (NOMs) used primarily to regulate the most economically
valuable fishing resources. In the case of abalone, the NOM which sets the regulations on
minimum size by species, closed season and closed areas is the NOM-005-PESC-1993.
Other complementary activities on fisheries management are undertaken by both, the
SEMARNAT (or “Secretaría de Medio Ambiente y Recursos Naturales”) and the
PROFEPA (or “Procuraduría Federal de Protección al Ambiente”). The Navy assists all
the aforementioned bodies in monitoring and detecting illegal activity undertaken at sea.
Relevant policies and guidelines
Article 36 of the Sixth chapter of the Fishing Law (LGAPS) states that the
instruments for fishery policy are the following: 1) the programs on fishing ordination, 2)
the fishery management plans, and 3) the concession or granting. Besides, Article 36 also
states that: “the authorities will promote and support the use of any control mechanism set
by resource users themselves, backed up on their traditional knowledge on local system
management. They will also promote the creation of community groups which assist in
protection and management of the fishing resources based upon the guidelines set at the
LGAPS”.
Although in Mexico there is little progress on fishing ordination programs, it is
acknowledged that in the case of abalone, all the above policies have been historically
applied to this fishery.
Institutional changes that have resulted from the implementation of the rebuilding
plan
Given that for this fishery, the set of stock recovery strategies have been implemented
since the 1990’s, it could be expected that, by this time, some of the elements contained
in it had been formally incorporated into the Fishing Law (LGAPS). Nevertheless, except
for the acknowledgement of promoting the work between the government and the
community of users on fishery management, the remaining elements, such as the
incorporation of the stock recovery programs as instruments on fishery policy in
Article 36 of the LGAPS, among others, have not been introduced yet. Thus, in Mexico,
the abalone stock recovery strategies have not produced any institutional change yet,
REBUILDING PLANS IN MEXICO – 9
REBUILDING FISHERIES © OECD 2012
neither for policies nor regarding the institutions. Moreover, it is currently known that
should a stock recovery strategy be cost-effective it needs careful planning and funds to
fully implement it.
Fisheries Rebuilding Plan Framework
Management response
Prior to the implementation of the recovery strategy, the abalone fishery was managed
by granting fishing licenses to fishers and by an instrument called NOM-005-PESC-1993.
The latter specified a minimum size for each abalone species and a closed season by area.
However, once the abalone catches declined abruptly, new management regulations were
set, including a catch quota and a banning of fishing with a technique called as “low-
tide”. Thus, although catch quotas started to be used in 1990, several documents state that
they were formally and systematically enforced from 1996-97 and onwards. Moreover,
since catch quotas were set, the CONAPESCA is supposed to be in charge of monitoring
and enforcing their observance. In general, it is acknowledged that the fishing effort
applied before the catch quota period, was higher than after it. The reason being that once
the catch quota was set, the fishing fleet dynamics changed because the fleet no longer
adjusted to natural dynamics but ones imposed by the catch quotas.
Since the end of the 1990s, several scientists conducted research on the culturing of
abalone. The government provided funds through the National Science and Technology
Council (CONACyT) and the results were spread among the scientific community, the
resource users and the government. Despite this, the aquaculture effort for abalone has
not resulted in any systematic stock enhancement and replenishment programs yet.
Monitoring and enforcement.
The monitoring of the stocks is undertaken by CONAPESCA but also by the fishers
themselves. The former has the responsibility of monitoring that the administrative and
regulatory measures are followed; do an evaluation of their success (or failure) and
alternatively, suggest new measures to reach the implicit target of recovering the stocks.
CONAPESCA is assisted by the Navy and PROFEPA (“Procuraduría de Protección al
Ambiente”). PROFEPA presses charges whenever illegal fishing is detected.
The cooperative fishers do have their own monitoring program. It has been estimated
that the cooperatives spend between 12,000,000 and 15,000,000 pesos per year (approx.
between EUR 705 882 and EUR 882 352) for monitoring activities and that each fishery
guard earns between MXN 12 000 and MXN 15 000 per month (or approx. between
EUR 706 and EUR 883). Moreover, several cooperatives have a radar system which
assists them in detecting illegal fishing. Despite this monitoring system, it is
acknowledged that illegal fishing still threatens the recovery of this fishery (Bórquez-
Reyes, et al. 2009).
Performance measurement and evaluation
The CONAPESCA, with technical support from INAPESCA, is in charge of
evaluating the success of the management of a fishery. Currently, the abalone fishery has
only one indicator to measure its performance, namely the increment of its stock biomass
from one year to the next. The general trend of recovery of the abalone stocks can be
examined or detected with data going back to 1990. Unfortunately, the current recovery
10 – REBUILDING PLANS IN MEXICO
REBUILDING FISHERIES © OECD 2012
strategy and the evaluation of its performance are based solely on biological grounds,
leaving out the other economic, social and institutional factors.
Post rebuilding management
The abalone fishery is still considered as deteriorated. No post rebuilding
management analysis has been undertaken yet.
Economic Aspects
The abalone is a highly valued resource, being sold by the fishing cooperatives at
MXN 200 per kg (about EUR 11.8). It is primarily a product for exportation, the main
markets being the USA and Asia. It is sold both, fresh and frozen in domestic markets
and canned and frozen in international markets.
With respect to prices for international markets, in 1997, a box containing 48 cans of
abalone with approximately 300 g (drained weight) each, is priced between USD 1 650
and USD 2 200. Similarly, in 2004, the same box had a price between 1,585 and 1,905
USD. In contrast, a similar box with 48 cans traded in the domestic market (which has an
abalone muscle of lower quality than the former) had a price ranging between USD 650
and USD 850 (INAPESCA, 2006).
Describe the use of economic analysis in the design stage of the rebuilding plan
The abalone fishery in Mexico is the one with the highest value per kilo produced (at
canned, frozen and fresh). Moreover, this is also the fishery with the highest income per-
capita. However, no specific economic analysis has been undertaken and used in the
design of the stock recovery strategy. There are some indicators which show fishery
managers the loss of profitability in this fishery. For instance, in 1991the fishery
production (fishery catches) value was USD 55 million whereas in 2002, the production
value was only USD 21 million (INAPESCA, 2006, p.12). In other words, a comparison
between only two years shows that this fishery-2002’s production as compared to the one
reported in year 1991, had lost about USD 34 million (approx. EUR 2 000 000). To this
amount we should add the expenses derived from fishers’ own monitoring (between
MXN 12 000 000 and MXN 15 000 000 per year or approx. between EUR 705 882 and
EUR 882 352 per year).
However, a note on transferable fishing property rights is relevant here. The Fishing
Law (LGAPS) states that the granting of concessions (or “concesiones” –lasting 25 years
but with a potential of renewal by another 25 years), could be sold. Nevertheless, in the
case of abalone, which has the cooperatives fishers as the de facto users, such a
transaction would not be allowed because anyone interested in buying such a granting
would need to become an entitled cooperativist fisher before buying it, and, a
cooperativist right or title cannot be sold but only passed down or inherited, from a
father/mother to his/her descendants.
Nevertheless, based on the expertise of the working team, it can be said that as the
abalone is a highly valued resource, its marked has, albeit partially, compensated a loss in
this fishery’s profitability because as the catches have declined, abalone became more
scarce and its market price increased. Moreover, an indicator of economic success would
be an estimation of the gradually increasing biomass of abalone (see Table 9A.1) times its
price in the market. However, this economic analysis has not been carried out yet.

Social Aspects
Key stakeholders affected by the rebuilding plan and their respective interests
According to the National Fisheries Institute, INP (2000), the first fishing cooperative
for abalone started in 1940. The history of the establishment of the other abalone’s
cooperatives is closely related to the human settlements of the western coast of the Baja
California. Thus, compared to most fisheries in Mexico, a striking characteristic of this
fishery is its geographical isolation, an aspect that precludes having human-related
pressures upon the abalone stocks. In this respect, except for the independent or free
fishers who practice illegal fishing, there are no other competing users for abalone and
therefore, the only group of people directly affected by the recovery strategy are the
cooperative fishers. However, this fishery has also both, direct and indirect users.
Although currently there are approximately 705 entitled fishers belonging to
22 cooperatives, it has been estimated that in total, there are about 20,000 people who
depend directly and indirectly from this fishery (INAPESCA, 2006; Valencia-Arámburo,
unpublished data).
Stakeholder participation (consultations, negotiations) in the design and
implementation of the rebuilding plan
To date, we have found no information on whether the cooperatives fishers
participated in any stage of the design of the abalone recovery strategy or if it was fully
designed by the government (INAPESCA and CONAPESCA).However, current
literature and related documents about this fishery show that since the abalone recovery
strategy started, in the 1990’s, the fishing cooperatives have actively participated in the
implementation of it. In particular, they participate in the stock assessment (biological
surveys) and in the negotiation of the TAC (in setting the size of the catch quota) as
suggested by the government.
Compared to other fisheries, these fishers are perceived by Mexican scholars as a
group with full awareness of the several problems affecting their fishery and who have
solutions to overcome them. In particular, this group of people has over 5 decades of
interaction with their resource base and therefore they are perceived as people with an
12 – REBUILDING PLANS IN MEXICO
REBUILDING FISHERIES © OECD 2012
ample local knowledge on the coastal ecosystem where its fishery is located and on the
several issues of legislation on fisheries. They have skills and expertise not only in
capturing abalone but in accounting, processing and marketing. They own several
processing plants and do have airplanes to transport their product out of their isolated
area. Moreover, these people do have their own monitoring and enforcement system and
posses ample expertise on collaborative research. In this respect, the government
(INAPESCA and CONAPESCA) acknowledge that most cooperatives have provided,
albeit partially, financial, logistic and technical support during the implementation of the
recovery strategy (INP, 2000; INAPESCA, 2006).
Implementation Issues & Lessons Learned
Key institutional and policy challenges faced
Despite a lack of formal documents entitled as rebuilding or recovery plan for
abalone, it is clear that actions and management decisions have been undertaken during
the last two decades, all of which correspond to a de facto fishery recovery strategy. At
the very beginning of the implementation of this strategy, many cooperative fishers
opposed to it, especially because the catch quota set was less than what they were used to
capture. Thus, during some abalone stock assessments, fishers asked the government for a
review of the data and the catch quota.
Given that current institutions on fisheries management lack a capacity (in budget and
staff) to fully implement a fishery recovery strategy, the fisher themselves devised their
own monitoring and enforcement systems. In the case of the abalone fishery, the recovery
strategy also included an active participation of fishers, especially with regards to the
collection of data, monitoring and enforcement, andin the discussions and negotiations of
the catch quotas, which at the end are decided upon by CONAPESCA. This collaboration
(government-resource users) has characteristics of both, participatory research and co-
management.
Estimate of the costs of designing and implementing the rebuilding plan
No data exists to fully estimate the cost of designing and implementing the rebuilding
plan. However, there are some clues, especially taking into account the cost of monitoring
and enforcement undertaken by the cooperatives, all which annually cost between
12,000,000 and 15,000,000 pesos (aprox. between 705,882.00 and 882,352.00 Euros). In
other words, the costs of designing and implementing the rebuilding strategy will be
well over 800,000 Euros per year.
Lessons learned
In general, the high value of abalone, together with a sudden drop of its catches,
leaded to agreements being reached and consensus on working towards the recovery of its
fishery, among authorities responsible for management and the highly organized
(experienced and well trained) cooperative fishers and technical staff from the
INAPESCA.
Lesson learned include: i) it is currently known that several factors and not only the
fishing mortality, are affecting the recovery of the abalone fishery and therefore it is
suggested that the current recovery strategy should be reviewed to incorporate this fact;
ii) the current recovery strategy is grounded solely on biological objectives; however, it is
suggested that other objectives (economic and social) should be, in the short run,
REBUILDING PLANS IN MEXICO – 13
REBUILDING FISHERIES © OECD 2012
incorporated to it; iii) given the high degree of organization of cooperative fishers, the
implementation of the recovery strategy has been legitimated by the resource users
themselves, with participatory research, monitoring and enforcement and, in general, with
characteristics of co-management; iv) currently, in Mexico, the recovery strategy for
abalone, as well as the research and management associated to it, is seen as a success;
with the green abalone stock showing signs of gradual recovery whereas the pink abalone
has been around a range of a steady biomass; v) should the Mexican government be
willing to fully rebuild or recovery its deteriorated fisheries, current fisheries policies
need to be reviewed; in particular, the successful elements of the abalone recovery
strategy need to be formally incorporated into the fishing legislation; and, a thorough
review of the government capacities on institutions (e.g., infrastructure, budget and staff)
appointed to fisheries management needs to be undertaken; and vi) the abalone recovery
strategy could be used as a successful case study by all, scholars, resource users, and
managers.

KEY INDICATORS
The key indicators introduced in Tables 9.2 and 9.3 were extracted from unpublished
Master of Science Thesis as well as from several internal (unpublished) stock assessment
reports available at the INAPESCA and CONAPESCA websites. The majority of those
indicators are not the result of a previously set annual target for this fishery; rather, they
correspond to annual stock biomass assessments used to set catch quotas. Table 9A.1
contains data of a gradually recovering stock biomass as estimated for the green abalone.
Currently, Mexican researchers and fishery managers consider this outcome as a success
of the green abalone recovery strategy. In contrast, Table 9A.2 contains the outcome for
several years of a stock biomass, the pink abalone, which shows no sign of recovery.
However, researchers and managers do consider that this stock has, in general, oscillated
around a steady biomass range. Note that in both tables, no data was available to
complete columns 5th to 8th because such estimations depend upon fishing mortalities for
which there are no available assessments.

The Red Grouper Fishery in Mexico
General Information.
The red grouper fishery encompasses the species Epinephelus morio and
approximately 36 other species; 20 of them being grouper species (Family Serranidae).
The majority of the captured species have a relatively high market value. According to
Arreguín-Sánchez et al. (1997), in this fishery, and during the period from 1980 to 1985,
the species E. morio represented, on average ~89% of the total catch; nevertheless, it has
been estimated that currently, this species only represents ~60% of the total catch. This
fishery is actually a sequential fishery, with three distinct fishing fleets, two Mexicans
and one Cuban. The Mexican artisanal fleet is referred to as the “la flota menor” (the
minor fleet) in Spanish. It is composed of approximately 3,440 boats with outboard
motors (with a HP not exceeding 115 HP) with fishing trips lasting from 1 to 3 days. This
fleet uses both hand-lines and bottom long-line. It operates from the shore to
approximately 36 m depth, and captures juvenile and sub-adult groupers (from 1 to 3
year-old) (DOF, 2004). The other Mexican fleet is called the “la flota mayor” which is an
industrial fishing fleet. This fleet is composed of 539 vessels using inside motors with
fishing trips lasting between 15 to 20 days. This fleet uses two fishing methods: a) a part
(approximately 40%) of the vessels use a major boat (a ”nodriza” or “mother” boat), also
called a carry-on-vessel, which is able to carry about 7 to 10 small boats locally known as
“alijos”. The “alijos” are 3 m long, wooden-made paddled boats with only one fisher
onboard. They use an easy to handle long-line and the catch is delivered to the mother
boat; and b) the remaining part of vessels use a long-line with approximately 1,500 to
2,000 hooks using power-winches. Presently, the Cuban fleet is composed of 12 vessels
of the industrial type. Each vessel is able to carry, on average, 6 outboard boats (Burgos,
2006). Before the year 2001, the fishing season was all year long with a peak in catches
during December-April, coincident with the red grouper's reproductive gathering.
However, since 2001, a closed season was set for one month during the reproductive
16 – REBUILDING PLANS IN MEXICO
REBUILDING FISHERIES © OECD 2012
gathering period. This fishery is considered to be a deteriorated fishery (“pesquería
deteriorada”, DOF, 2006, p. 51) but also as an overexploited one (“pesquería
sobreexplotada”, INAPESCA, 2006, p. 516). It lacks a formal recovery plan, but does
have a management plan devised by INAPESCA in the year 2003 (INAPESCA, 2006;
see also section 1.3).
Boats in the Mexican fleets are obliged to havefishing permits (“permisos de pesca”)
without any limit on their maximum catch whereas a catch quota is set to the Cuban fleet.
However, in Mexico, this fishery was, for several decades, considered as an open access
fishery because before the year 2001, any boat or vessel which wanted to get into the
fishery was able to do so. Thus, before the year 2001, the regulation of this fishery was
based only on a minimum fish size. Because of a gradual drop in yields from 2001 and
onwards, , a closed season regulation was put in place, aimed at protecting spawning
stock. Currently, the closed season runs from 15 February to 16 March.
Species
The resource base of this multi-specific fishery is composed by the red grouper,
Epinephelus morio, plus by the following grouper species: Epinephelus flavolimbatus,
Epinephelus nigritus, Epinephelus guttatus, Epinephelus drummondhayi, Epinephelus
adscensionis, Epinephelus itajara, Epinephelus mystacinus, Epinephelus niveatus,
Epinephelus striatus, Mycteroperca bonaci, Mycteroperca microlepis, Mycteroperca
venenosa, Mycteroperca interstitialis, Cephalopholis cruentata, Cephalopholis fulva,
Dematolepis inermis, Gonioplectrus hispanus, Paranthias furcifer, Mycteroperca phenax,
Mycteroperca tigris. Moreover, this fishery also captures the following commercially
important demersal fish species, Lutjanus campechanus, Lutjanus analis, Lutjanus
griseus, Lutjanus synagris, Lutjanus buccanella, Lutjanus vivanus, Lutjanus jocu,
Rachycentron canadum, Ocyurus chrysurus, Calamus bajonado, Calamus campechanus,
Haemulon plumieri, Seriola zonata, Rhomboplites aurorubens, Lachnolaimus maximus,
and Lopholatilus chamaeleonticeps.
Fishing Area(s)
The red grouper fishery operates on almost the whole continental shelf of the Yucatan
Peninsula, although there are several specific areas with higher fish abundance than
elsewhere (Figure 9.2). It is known that the grouper fish schoolings undertake seasonal
movements (López-Rocha and Arreguín-Sánchez, 2007) and it has been reported that one
of the most important areas for reproductive gathering of this species is located at the
Centre-Eastern part of the Peninsula. Reproductive gatherings take place from Winter
until early Spring, a time period when, due to their higher abundance, the species become
more vulnerable to fishing (Arreguín-Sánchez and Pitcher, 1999, López-Rocha and
Arreguín-Sánchez, 2008). The peak of the fishing season coincides with the time of
reproductive gathering. Other studies have reported that high densities of juveniles and
pre-adults of grouper occur at a coastal area located in front of Dzilam de Bravo and
Laguna Yalahau.Due to this the fishing fleets also show some seasonal dynamics, with
the artisanal fleet being primarily found in coastal, shallower areas, whereas the industrial
and Cuban fleets operate at deeper waters. Moreover, it is known that there are overlaps
between all fishing areas with approximately 60% overlapping between the artisanal and
the industrial fleets.

Timeframe for rebuilding plan (years)
The current official management rules set at the National Fisheries Charter (NFC) do
not lay out an explicit strategy or aim at recovering this fishery. Therefore, no timeframe
for rebuilding has been set officially yet (however see sections below).
In contrast to what has been explicitly stated with regards to the abalone fishery at the
NFC, i.e. about the need to recover the fishery stocks, and about a recovery strategy, no
similar statement was found at the NFC to the red grouper fishery. It was, however, found
that the NFC publications from the years 2004 and 2006, in addressing the current status
of the red grouper fishery, recognize, using exactly the same wording, that (DOF, 2004,
p. 153; DOF, 2006, p. 51):
“Taking into consideration the Reference Points set to Epinephelus
morio, this fishery is currently deteriorated
Also, several technical reports undertaken by INAPESCA and its research units (the
Centros Regionales de Investigación Pesquera, CRIP), have explicitly addressed the
topic of recovering this fishery. Thus, Burgos (2006, p. 10) states that:
“The (red grouper) fishing resource will recover its stock only after
protection guidelines are set and responsible fishing promoted
Several scholars, including technical staff from INAPESCA who have been studying
this fishery for over a decade, have already worked on several red grouper stock recovery
18 – REBUILDING PLANS IN MEXICO
REBUILDING FISHERIES © OECD 2012
scenarios (see INAPESCA, 2006).However, there seem to be a lag between policies
addressing the red grouper fishery at the NFC and what scholars have been working on
the fishery during the last 5 years, i.e., examining scenarios that would potentially allow
the recovery of the red grouper stock. Despite this, the results obtained from scholars and
staff from INAPESCA from their academic exercises on stock recovery scenarios could
easily be incorporated into the NFC and other management instruments. For example, to
date these people have set short-run (5 years) and long-run (20 years) Reference Points
(INAPESCA, 2006) both which could be used in future formal stock recovery plans.
In general, this fishery does have, from 2001 onwards, relatively new management
actions, that implicitly point toward an effort to avoid its collapse (these actions are
explained in section 1.5).
Major identified sources of mortality/threats to rebuilding
Given that this fishery, had been for several decades, an open access fishery, it is
recognized as overcapitalized. Fishing mortality is seen as one of the major sources of
mortality to this stock and therefore one of the major threats to rebuilding it. Similarly,
some authors report that the red grouper stock is currently overharvested due to increased
overfishing which resulted from an uncontrolled increase of the minor fleet (Hernández
et al., 1999),which primarily catches juveniles and pre-adults. Moreover, Arreguín-
Sánchez et al. (1990) also point out that several factors may have caused a fault in annual
recruitment for this species and therefore a decline in its stock; among them being, the
occasional oil spills that occurred at the Campeche Bank (CB), the changes in water
temperature detected at this same area (CB), and changes to the red grouper’s habitats due
to hurricanes. Furthermore, Arreguín-Sánchez et al. (1996, 2008) hypothesized that the
Campeche Bank, as an ecosystem, has, during the last 4 decades experienced a decreased
carrying capacity which could have caused a decline in the stock of several fisheries,
including the red grouper. This, however, is a topic that needs to be further addressed in
future fisheries studies.
As this is a multi-fleet fishery, there is conflict of interests among different
stakeholders involved in the fishery. However, in Mexico, there is an important degree of
experience on fisheries conflict resolution (e.g the Pacific shrimp fishery; the abalone
fishery) which can serve as lessons learned for the red grouper fishery.
Rebuilding goal/target (MSY, MEY etc.)
No formal or explicit rebuilding plan has been designed for this fishery yet. Despite
this, the NFC (DOF, 2006, p. 51) states that, given the current status of the red grouper
fishery, there is a need of implementing its new management plan, as devised by
INAPESCA in 2003, which is based on setting both, the Reference Points (TRP and LRP)
and a catch quota per fishing fleet. In turn, the Target Reference Point (TRP) was set as
(INAPESCA, 2006, p. 515):
TRP = 50% B0 = 50% B (1958)
B (1958) = 248,548 t
TRP = 124,178
Whereas the Limit Reference Point, (LRP) was set as (INAPESCA, 2006, p. 515):
LRP = 30% B0 = 30% B (1958)
REBUILDING PLANS IN MEXICO – 19
REBUILDING FISHERIES © OECD 2012
B (1958) = 248,548 t
LRP = 78, 945 t
In 2003, the red grouper biomass was assessed, resulting in 46,487 t which is well
below the Limit Reference Point because it represents only 18.7% of the reference
biomass (B (1958)) (INAPESCA, 2006, p. 516). However, given the multi-fleet nature of
the red grouper fishery as well as its latest estimated biomass [B (2003) = 46,487 tonnes],
our analysis indicates that, at present, the Target Reference Biomass (TRP) and Limit
Reference Biomass (LRP) may be too high to be the only targets. Hence, in accordance
with what INAPESCA has recommended this fishery should be managed based on catch
quotas per fishing fleet, which should be fully discussed and negotiated with the involved
fishers. In deciding on a catch quota to this fishery, for each year, the red grouper stock
biomass would be estimated based on biological surveys and the decision rule in setting a
catch quota would be analogous to how it is currently done for the abalone fishery, i.e. the
annual biomass would be simply compared against the one estimated the previous year.
Hence, the decision rule in setting the catch quota would then proceed as follows: a) the
catch quota would be decreased, if there is a decrease in measured biomass between
consecutive years; b) the catch quota would be the same as compared to the one set the
previous year, if the stock biomass showed neither an increase or decrease, or c) the quota
would be increased as compared to the one set the previous year, if a growth in stock
biomass was detected. As with the abalone fishery, this recovery strategy is based on the
rationale of controlling the annual catch of the red grouper fishery, from one year to
another, aimed at maintaining the stock biomass at a level, which would maximize its
yield. Moreover, a catch quota should be selected in such a way that, while the fishery
operates at acceptable economic levels as assessed by the stakeholders, would allow for a
gradual steady recovery of the stock biomass.
The proposal above is based solely on biological grounds it is nevertheless
recommended that other objectives should be examined and considered in the recovery
plan. Ideally, these objectives should include other aspects (see Díaz-de-León and Seijo,
1992) including economic, social and ecological-biological criteria.
As previously stated, this fishery does have recent management measures in place to
avoid its collapse. Actions include the implementation of a negotiated closed season
during the reproductive gathering of fish. In other words, the closed season was not
simply imposed by the government but agreed upon with the interested parties
(cooperatives fishers, “permisionarios”, government, and scholars). However, to be
considered as a recovery strategy, these management rules still seem weak to ensure the
recovering of any fish stock.
Overview of issues
The red grouper and associated species are valuable resources which form the
resource base of this most socially important fishery (in terms of number of generated
jobs) of the Yucatan peninsula. Thus, although devising this plan seems a complex and
difficult task, there is little doubt that most stakeholders would be interested in
collaborating on it.

REBUILDING FISHERIES © OECD 2012
Institutional Framework
Legislation – Authority
In Mexico, the “Ley General de Acuacultura y Pesca Sustentable” (from here
onwards referred to as “LGAPS”, or the General Law on Sustainable Fishing and
Aquaculture) regulates the access, use and management of the fishery resources. The
authority responsible of the enforcement of this legislation is a Secretariat called as
SAGARPA (or “Secretaría de Agricultura, Ganadería, Pesca y Alimentación”); to this
end, two administrative bodies of SAGARPA, the INAPESCA (“Instituto Nacional de
Acuacultura y Pesca”), and the CONAPESCA (“Comisión Nacional de Pesca y
Acuacultura”) undertake the several duties and enforce the regulations, as stated at the
LGAPS, on fishing and aquaculture. The INAPESCA is in charge of coordinating and
leading the scientific and technical research on fishing and aquaculture but also in
designing and updating the National Fisheries Charter (NFC). CONAPESCA is in charge
of executing any technical recommendations pointed out by the former; authorizes the
fishing permits and fishing concessions based on the management regulations set at the
NFC and, whenever a boat or fisher is seen or caught with fish product outside the
authorized fishing season, has the authority to take it off. Note that in authorizing the
permits, CONAPESCA uses the management regulations set out by the NFC.
The management of the red grouper fishery is based on the Norma Oficial Mexicana,
NOM-009-PESC-1993, which was recently updated in NOM-065-PESC-2007 (DOF,
2009). It contains the regulations on minimum size by species, including a gradual
increase of the minimum size, of 30.9 cm total length (TL) in 2009, to 36.3 cm TL in the
year 2010. Moreover, DOF (2007) decreed a closed season, lasting one month, for this
fishery.
The Fishing Law or LGAPS also stipulate the setting up of Fishery Councils at the
state level (or “Consejos Estatales de Pesca”) representing the relevant stakeholders. In
Yucatan, this Council was already established and was instrumental when all interested
parties (government of the three levels, fishers, “permisionarios” and the academia)
agreed upon setting a closed season to the red grouper during the reproductiveperiod.
Relevant policies and guidelines
Article 36 of the Sixth chapter of the Fishing Law states that the following
instruments are used for fisheries management: 1) the programs on fishing ordination,
2) the fishery management plans, and 3) concession or granting. Article 36 also states
that: “the authorities will promote and support the devising of any control mechanism set
by resource users themselves, backed up on their traditional knowledge on local system
management. They will also promote the creation of community groups which assist in
protection and management of the fishing resources based upon the guidelines set at the
LGAPS”. Hence, such policies should assist in the design and implementation of a fishery
recovery plan.
The current Fishing Law also encourages change in the currently centralized (top-
down) system of fisheries management, by handing down many of these duties either to
the states/regions or to the municipalities (in the case of demersal fisheries). Thus, given
the social importance of some fisheries, several states, like the Yucatan, do a have their
own Fisheries Secretariat. For the red grouper stock recovery plan to be more cost-
effective, a coordinated action needs to be agreed by the three level of government
(municipal, state, and federal). An example is when the most relevant stakeholders agreed
REBUILDING PLANS IN MEXICO – 21
REBUILDING FISHERIES © OECD 2012
upon a closed season for the red grouper fishery. Then the Fisheries Secretariat of
Yucatan implemented policies aimed at assisting fishers and their families with in-kind
and cash income during the closed season (see ).
If in the short and medium term, a reduction in fishing effort is necessary to recover
this fishery, new policies to back up this reduction need to be put in place. In particular,
there is some experience in Mexico with reducing the fishing effort through a policy on
boat or vessel voluntary retirement (or “retiro voluntario de embarcaciones”). An
example of this policy has been applied in the Pacific shrimp fishery (M. Valencia-
Arámburo, personal observation). Based on the lessons learned from that fishery, a policy
for the red grouper fishery could proceed as follows: a) the government would assess the
economic value of, say, a standard boat of the minor fleet including its fishing gear and
outboard motor. Based on this estimation, the government offers a specific amount of
money to each fisher (i.e., boat owner) who is instead willing to trade his or her boat, gear
and equipment, together with its fishing permit, for the amount of money offered. Once
this transaction is completed, the boat is scrapped and the fishing permit discarded. This
policy should continue until, the fishery operates at its desired levels (as assessed by the
management authority and the involved parties). However, this process will be even more
complex in the coast of Yucatan than in the Pacific shrimp fishery. The reason being that
in the red grouper fishery, many of the artisanal fleet's boats do switch to capturing other
species along the year. As an example, many boats switch to capturing octopus during
several months of the year (August to November). Hence, the above retirement policy
would apply to the boats targeting red grouper exclusively. Alternatively, what should be
retired from the red grouper fishery should be the fishing permit (to capture red grouper)
and the fishing gears used for this species.
Moreover, an inter-sector analysis of the region is needed. In particular, the region as
a whole (Yucatan Peninsula) should be examined and focused on the potential productive
sectors wherein new jobs or small business could be created for retired fishers. Thus,
ideally, government would promote (public and private) investments on those productive
sectors.
Finally, two other aspects should be taken into consideration in the recovery plan,
namely a new policy concerning the Cuban fleet and a better control of the “pescadores
libres” (free fishers).
Institutional changes that resulted from the implementation of the rebuilding
plan
There is no rebuilding plan yet but only an agreed upon closed season among the
stakeholders including the three-level government, to avoid the collapse of this fishery.
Fisheries Rebuilding Plan Framework
Management response
There is no rebuilding plan in place yet. It is uncertain, if a policy on the voluntary
withdrawal of vessels from the red grouper fishery is launched whether the reduction in
fishing effort will be rapid and effective. However, a desired management response
would be that an improved and sustained coordination among the three government levels
resulted in recovering this fishery. This coordination would need to be part of the Fishery
Council from Yucatan including the participation of neighbouring coastal states.
22 – REBUILDING PLANS IN MEXICO
REBUILDING FISHERIES © OECD 2012
From the fishers side, and because since the implementation of the closed season
there has been a slight increase in red grouper catches (from 2003 to 2009), they perceive
that the closed season, implemented since 2003, has been useful in increasing the stock
biomass (V. Alcántar, Head of the Fisheries Secretariat at Yucatan, personal
communication). Thus, the fishing community could actively participate in observing the
management rules.
With respect to controls, they would be based on the comparison of the stock biomass
from one year to the next as well as the total number of fishing permits issued for this
fishery.
As previously stated, in order to recover this fishery, one of the new management
tools would be to close some of the areas which are habitat for juveniles and young
adults.
Some research institutions from the Yucatan Peninsula, like CINVESTAV,has for
several years now been conducting research on the culturing of red grouper (A.M. Arce-
Ibarra, personal observation). The government has, through its National Science and
Technology Council (CONACyT), provided the required funds and their results have
been distributed among the scientific community. Nevertheless, it is unknown whether
the government knows about these results or if they will be interested in undertaking
stock enhancement and replenishment programs for this species based on those results.
Monitoring and enforcement
Once the objectives of a recovery plan are set, and in an analogous form to what is
currently done at the Abalone fishery, the government, i.e., CONAPESCA, could be in
charge of the monitoring and the enforcement of rules. To complement CONAPESCA's
enforcement, local fishers should participate too, but they would need to devise their own
monitoring program. In this respect, fishers from Yucatan could learn from the several
successful experiences of fisheries co-management in other places. One of these is the
spiny lobster fishery located at the centre of Quintana Roo (one of the three states of the
Yucatan Peninsula). In this fishery the community rules for monitoring and enforcement,
as set by the cooperative fishers themselves, are even stricter than the ones devised by the
government. To this end, the fishers would need to organize themselves to get funding to
implement their own monitoring program.
Performance measurement and evaluation
The CONAPESCA, assisted with technical support from INAPESCA, is the
institution in charge of evaluating the success of the management of a fishery.
Nevertheless, the fishers and other stakeholders should also participate in the evaluation
of the progress of the stock recovery.
As previously stated, once the recovery plan is set up, the red grouper fishery would
have its stock biomass compared, from one year to the next, as the indicator of the
recovery performance. Nevertheless, other indicators based on economic, social and
institutional criteria should be also devised and considered. In particular, it would be
necessary to undertake a bioeconomic analysis for the red grouper fishery and derived
from this study, the average net return per trip could be used as another indicator to
measure the performance of this fishery.

Economic Aspects
Taking into consideration the GDP by productive sector, the red grouper fishery
contributes with 1.8% of the GDP within the fisheries sector (SAGARPA, 2006).
The red grouper is a relatively valuable resource, prices reaching up to MXN 70 per
Kg (about EUR 4 per kg) in domestic markets. It is a product for both, international
(about 70% of total catch) and domestic (about 30% of total catch) markets, the USA
being the most important market with exports ranging between 3 000 and 4 000 t since
1995 (INAPESCA, 2006). However, in contrast to the observed domestic price, the price
paid for imported, fresh product in 2004 was MXN 27 per Kg (about EUR 1.6 per Kg).
In 2003, even with its lowest historical record in catches, of 5,551 t, the red grouper
fishery production value was MXN 111 000 000(about EUR 6 529 411). During the last
five years the red grouper production reported an average value of 7 965 tonnes
(INAPESCA, 2006).
Uuse of economic analysis in the design stage of the rebuilding plan
Despite the social importance of the red grouper fishery we found no specific social
or bioeconomic analysis undertaken for this fishery. However, in devising a recovery plan
for this fishery, a trade-off between social (generation of jobs) and economic criteria
should be made, taking into account the sustainability of the resource.
An analysis based on market issues should be considered when devising the recovery
plan. Among such issues are: the size of captured fish (compared against what sizes are
demanded in the markets); and the transferable property rights of the granting (or
“concesiones”) of the “permisionarios”, a permit that can be sold in commercial
transactions.
In contrast, the cooperativist fishers would continue being ruled by what there is now
the norm (i.e., a cooperativist right or title cannot be sold but only passed down or
inherited, from a father/mother to his/her descendants).
However, based on the expertise of the working team, it can be said that to some
extent (although less than to what happens to Abalone), the red grouper market could,
albeit partially, compensate a loss in this fishery’s profitability because once its catches
have declined, this species would become a scarcer resource and most likely its market
price will increase. Similarly, an indicator of economic success would be an estimation of
the gradually increasing biomass of red grouper times its price in the market. However,
this economic analysis has not been done yet neither in any of the documents issued by
the government or in the scholarly literature on red grouper.
Social Aspects
Key stakeholders affected by the rebuilding plan and their respective interests
There is no formal rebuilding plan yet, however, according to INAPESCA (2006),
three groups of people participate in the red grouper fishery: a) the entrepreneurs called
locally as “Los Industriales”, b) the fishing cooperatives, and c) other organizations and
the free fishers (or “pescadores libres”). The first own the majority of processing plants as
well of the Mexican industrial fleet and of the majority of artisanal boats. The
cooperatives sell their captured fish to the industrial group but own several artisanal boats
and of some processing plants. The third group of people, belonging to the CNC or
24 – REBUILDING PLANS IN MEXICO
REBUILDING FISHERIES © OECD 2012
“Confederación Nacional Campesina” and the so called Solidarity groups “grupos de
solidaridad”, does not own boats or processing plants but usually sell their catches to the
former group. The free fishers are a part of this group.
“Los industriales” and then the cooperatives would be the two groups most interested
in working collaboratively and agreeing upon a stock recovery plan. Nevertheless, not all
members of the second group have their fishing licenses or fishing permits yet (i.e.,
several of them work without fishing permits); therefore, this would be the first topic to
address and solve within the group. In a similar way, the third group is a cause for
concern because, very likely, most of them do not always have the necessary fishing
permits. Therefore, if no new fishing permits are issued for this fishery, the groups that
would be most affected would be the third one and to a lesser extent, the second one.
On the other hand, this fishery has also both, direct and indirect users. According to
INAPESCA (2006), the red grouper fishery provides jobs to approximately 80% of the
total people involved with Yucatan fisheries. In terms of number of full-time fishers, it is
estimated that the fishery employs between 10,000 to 12,000 people plus a 4,000 to 7,000
part-time fishers (total range 14,000 to 19,000 fishers). Moreover, the processing plants
sustain approximately another 2,000 jobs.
With respect to other directly competing users for red grouper, there seems to be
none, except the oil industry that is currently based at the Campeche Bank. Unfortunately
the fisheries and the oil industries do have conflicting interest that would need to be
addressed at higher political levels.
Stakeholder participation in the design and implementation of the rebuilding plan
There is no rebuilding plan yet but rather voluntary stakeholder participation.
However, one of the most recent outcomes resulting from this stakeholder participation
was the agreed upon closed season for the red grouper (DOF, 2007).The major
stakeholders participated in this negotiation process: cooperativist fishers,
“permisionarios”, government, and scholars. This illustrates that, despite that the fishery
is being considered as one with many internal conflicts among users by some people,
there is will to undertake collaboratively work among stakeholders. We have no doubt
that these people will be willing to continue its participation in the stock assessment
(biological surveys) and in the negotiation of any TAC.
Compared to the abalone fishery, we do perceive these stakeholders as a group with a
certain degree of awareness of the several problems affecting their fishery and who may
have solutions to them. Again, this group of people has over 5 decades of interaction with
their resource base and therefore they are perceived to be people with an ample local
knowledge on the coastal ecosystem where this fishery is located. Many of them do have
skills and expertise not only in capturing red grouper but in accounting, processing and
marketing.
Moreover, the cooperative fishers do posses ample expertise in undertaking
collaborative research. In this respect, regional research institutes, such as CINVESTAV
and ECOSUR acknowledge that several cooperatives have provided, for several years
now, some logistic and technical support during their fieldwork.
Equity or distributional issues raised as a result of the implementation of the
rebuilding plan; if so, explain how these issues were addressed
No information was found on any equity or distributional issues for this fishery.
REBUILDING PLANS IN MEXICO – 25
REBUILDING FISHERIES © OECD 2012
Compensation mechanism used in support of rebuilding measures
After the closed season for red grouped was implemented in 2003, the government of
Yucatan sought funds to partially support fishers and their families during this period.
Thus, a program for temporal job (“programa de empleo temporal”) was launched. The
people who benefited from the program were fishers working in both the artisanal and
industrial fleets who were enlisted at the “Padrón de Pescadores Activos del Litoral
Yucateco” (or in a List of active fishers from the coast of Yucatan). Notably, the
municipal government assisted the state government in reviewing the list of benefited
fishers. The program included both, in-kind and cashpayments. The in-kind support, it
was a weekly basket of groceries with basic food (“despensa”). The cash payments were
$300 pesos (about 17.6 Euros) per week. In turn, the fishers undertook some duties
related to community well-being. The fund to cover the program came from the state
government (i.e., from the Secretaría de Fomento Agropecuario y Pesquero, as well as
from DIF).
Implementation Issues & Lessons Learned
Key institutional and policy challenges faced
Despite a lack of formal document entitled as rebuilding or recovery plan for the red
grouper, some management actions and a negotiated closed season were detected which,
altogether are perceived as a genuine will of stakeholders to work together to avoid a
fishery collapse. Thus, these management actions could be considered as the first step in
devising a stock recovery plan to this fishery.
Prior to the implementation of any recovery plan for the red grouper, stakeholders
may be sceptic about being ruled by new management guidelines because this fishery has
historically been an open access fishery.
During the implementation of the recovery plan for an open access fishery, the
challenges faced could be along the lines of reaching effective communication among
stakeholders: no doubt each group will speak a “different” language or use a different
codices of communication signs; therefore, participatory workshops should be undertaken
to avoid mistrust. Thus, setting any compromise clearly from each group since the
beginning will be needed. Moreover, in assessing the stock and setting the catch quota,
all procedures to be followed should be clear enough to all involved parties. Finally, the
evaluation and performance measurement of stock recovery should be clear to everyone.
In summary, given the size of the red grouper fishery, enforcement of management
rules undertaken solely by the government would not be cost-effective. In this respect,
government and scientists should work in collaboration with government and resource
users to ameliorate the fisheries management in a form of co-management.
Lessons learned
The red grouper fishery is from a social viewpoint the most important fishery of the
Yucatan Peninsula. A gradual decline in catches lead to the acknowledgment that the
fishery is deteriorated and secondly, that new management actions were needed to avoid
collapse. To this end, a striking negotiated agreement, within an apparent fishery full of
internal conflict, was reached among the interested parties (three level-government:
municipal, state and federal, as well as cooperative fishers, “permisionarios”, scholars,
and technical staff from INAPESCA).This agreement concerns a closed season to this
26 – REBUILDING PLANS IN MEXICO
REBUILDING FISHERIES © OECD 2012
species during winter, the season of high abundance due to the reproductive gathering of
this species.
Lesson learned include:
It is currently known that the red grouper fishery is overcapitalized; hence, decreasing the
fishing mortality is one of the major factors in possibly rebuilding this fishery. However, it is
suggested that other environmental and human-derived factors, like the increment of water
temperatures as well as a decrease in the productive capacity of the Campeche Bank wherein an
oil industry is based, should be further looked into.
There is political will to discuss and devise a recovery plan for this fishery. To this end, one of
the first challenges will be along the lines of establishing effective communication among
stakeholders who have been historically participating, on their own, in an open access fishery.
The recovery plan should not be based solely on biological grounds; hence, the objective of the
plan should be include other factors such as social and economic criteria, while ensuring
sustainability.
Another challenge to be faced ís to review and then control the total number of boats (both,
legal and illegal) participating in this fishery.
Given the size of the red grouper fishery and the high costs of enforcement, the recovery plan
needs to be deemed legitimate by the resource users themselves, with participatory research,
monitoring and enforcement and, in general, with the characteristics of co-management;
As a reduction in the fishing effort is necessary, a program of voluntary scrapping of boats
should be implemented. Also part-time job programs or similar measures should be devised to
assist fishers who are willing to both, observe the new management rules as well as voluntarily
retire from the fishery.
The Mexican government should consider how to deal the current participation of the Cuban
fleet.
Should the Mexican government be willing to successfully recover its deteriorated fisheries,
current fisheries policies need to be revised.

Key indicators
R: With no stock recovery plan to the red grouper yet, there are no key indicators
which could be used for this fishery. The key indicators introduced in Table 9B.1 were
extracted from INAPESCA (2006, from Figure 3, p. 516). Those indicators are not the
result of a previously set annual target for this fishery, rather they correspond to stock
assessments simulation models used to estimate the Reference Points (TRP and LRP). In
this case, the year 20 is a hypothetical timeframe with an estimated stock recovery value
(Table 9B.1).

The Pink Shrimp Fishery in the Campeche Sound
General Information
The pink shrimp (Farfantepenaeus duorarum) fishery started in the 1940s. Three
fishing fleets, one domestic and two foreign fleets -one from the USA starting in 1947,
and another from Cuba starting in the 1960´s, used to take part in this fishery. Both of the
foreign fleets stopped fishing in 1979. The catch of pink shrimp peaked at close to 20 000
tonnes in the early 1970's whereas the lowest historical catch of 1 200 tonnes was
recorded in1997. In general, it is acknowledged that the development of this fishery was
relatively fast and unplanned, with several technological improvements introduced in the
trawling fishing gears over several years, and as a result the catch per unit of effort
among years are not comparable (INAPESCA, 2006).
A steady stock decline for this species started in the mid 1970s and continued until
the end of the 1990s. This fishery is considered as a collapsed one by some authors
(Gracia et al., 1997) as well as a deteriorated resource according to official, governmental
documents, such as the National Fisheries Charter, NFC ( where this species is portrayed
as “recursos deteriorados” at DOF, 2004, p.131, and as “los recursos están deteriorados”
at DOF, 2006, p. 24).
With respect to the domestic fleet, the pink shrimp fishery is a sequential fishery,
where two fleets operate, an industrial fleet and an artisanal fleet. Artisanal boats, with
outboard motors, originating from Campeche and Yucatan use to fish upon two shrimp
species, Xiphopenaeus kroyeri and Farfantepenaeus duorarum, with the former being the
target species and juveniles of the latter the by-catch species. In the past, there was an
artisanal fishery targeting at F. duorarum in coastal lagoons, however, at present, fishing
upon subadults and juvenile pink shrimp as target species either at coastal lagoons or
estuaries is explicitly forbidden (Gracia, 1997). Despite this restriction, and due to shrimp
larvae being naturally trapped at the coastal zone, currently this species is also caught in
relatively small quantities by an unknown number of artisanal boats, at the northern part
of the Yucatan Peninsula.
This fishery is managed by various regulations concerning for example as minimum
size, a closed season - set by INAPESCA, to protect parental stock; a minimum opening
size for nets, restriction on fishing gears to protect turtle populations, and closed areas
(DOF, 1993 and 1997). During the year 2009, the closed season was set from 20 May to
31 October.
Species
Target species is the pink shrimp, Farfantepenaeus duorarum, with Farfantepenaeus
aztecus, Litopenaeus setiferus, and Sicyonia brevirostris being by-catch species.
Fishing Area(s)
The pink shrimp fishery is located at the Campeche Sound - a continental shelf
system with a seaward limit defined by the 200 m isobath. Besides sustaining several
commercial and subsistence fisheries, the Campeche Sound is economically important
because approximately 70% of oil and natural gas produced in Mexico comes from this
region. The pink shrimp´s fishing area is located between 18° 45’ and 21° 25’ N, and 90°
30’ and 92° 30’ W, at depths ranging primarily from 30 m to 70 m. In addition, the
fishery has two closed areas; a coastal one, from 0 to 15 miles, along Campeche state, to

REBUILDING FISHERIES © OECD 2012
protect pink shrimp juveniles, and another area encompassing oil marine platforms (see
Figure 9.3).
Figure 9.3. Fishing area for the pink shrimp at the Campeche Sound (in gray color)
Blue and red lines represent restricted fishing zones due to the establishment of oil extractive industry
Timeframe for rebuilding plan
Despite that the NFC has accorded the pink shrimp fishery the status of a deteriorated
resource, at present, and contrary to what was found in abalone fishery, the current
official management rules set at the NFC do not set forth an explicit strategy or aim to
recover this fishery. Therefore, no timeframe for rebuilding has been set officially yet
(see however sections 1.5 and 1.6, below).
A statement from INAPESCA (2006, p. 466- 470) written by a research team,
including INAPESCA´s staff, pointing out the need of devising a stock recovery strategy
for pink shrimp: “Existe la necesidad de recuperar las poblaciones de camarón blanco y
rosado” (There is a need of recovering the stocks of white and pink shrimps.) Similarly,
Arreguín-Sánchez et al. (2008, p. 90) studied Pink shrimp and reported that: “In the case
of southern Gulf of Mexico, fishermen clamour for actions aimed at recovering the
shrimp stock”.
Thus, despite having no formal or explicit recovery objective yet, several scholars
including technical staff from INAPESCA who have been studying this fishery for over a
decade and who are aware of its crisis, have already examined, as academic exercises,
several pink shrimp stock recovery scenarios (see Arreguín-Sánchez et al., 2008a and
Arreguín-Sánchez et al., 2008b). In this respect, and similarly to what was found in other
Mexican fisheries, there seems to be a lag between the updating of governmental policies
and management rules addressing the pink shrimp fishery at the NFC and the stock
recovery scenarios being examined by researchers.
30 – REBUILDING PLANS IN MEXICO
REBUILDING FISHERIES © OECD 2012
Major identified sources of mortality/threats to rebuilding
In 1994, the pink shrimp fishery was formally declared to be in crisis. At that time, it
was thought that overfishing was the main cause of the steady decline of shrimp stocks.
However, during the early 2000s, new studies on this fishery showed that the rate of this
species’ recruitment had been decreasing since the end of 1970´s which pattern coincided
with a decrease in global primary productivity of the Campeche Sound. Moreover,
changes in sea surface temperature and in salinity were also detected at this area
(Arreguín-Sánchez et al., 2008), the latter being inversely related to shrimp stock
abundance (Ramírez-Rodríguez et al., 2000). Therefore, a major threat to rebuilding is the
uncertainty of changes in the environment. Moreover, no studies were found that
addressed or monitored any shrimp stock- environment relationship; hence, there is
uncertainty on the reactive capacity of shrimp populations to natural or human-induced
events (such as oil spills). Finally, a potential threat could arise from the fact that since
2003, this fishery (together with all Mexican shrimp fisheries) is subsidized (see more
details in section 4 Economic Aspects).
Rebuilding goal/target (MSY, MEY etc.)
No formal rebuilding plan or target has been devised to this fishery yet. In 1994,
when the pink shrimp fishery was formally declared to be in crisis and it was thought that
the factor causing stock decline was the fishing mortality; the short-term goal was to
control fishing effort as to allow a recovery of 50% of stock biomass (DOF, 2002).
Previously, the NFC of the year 2000 (DOF, 2000) portrayed this fishery as deteriorated
and recommended not to increase its fishing effort. Currently, the reference point for this
fishery set at the NFC (DOF, 2006, p.24) is not to increase the last five-year average
catch (or “no aumentar la captura promedio de los últimos 5 años”). Moreover, the
current management regulations imposed a closed season and closed areas to protect the
shrimp reproductive stock and to increase the yield per recruit for this species (DOF,
2006, p. 24).
In terms of monitoring the recovery of the pink shrimp stock, it is recommended that
this fishery should be managed in an analogous fashion to what is currently being done in
the abalone fishery (see Mexican case study number 1), namely based on catch quotas per
fishing fleet or alternatively quotas per fishing area, an aspect which should be fully
discussed and negotiated with the involved fishers and the private sector.
Thus an analogous recovery strategy for pink shrimp would include using a catch
quota where each year, the shrimp stock biomass would be estimated based on biological
surveys and the decision rule in setting the quota would be as follows: the annual biomass
of this species would be compared to the one estimated the previous year. Hence, the
decision rule in setting the quota would, again, proceed as follows: a) the catch quota
would be reduced, as compared to the one set the previous year, if there was no positive
growth but a decrement in the shrimp stock biomass; b) the catch quota would be set the
same as compared to the one set the previous year, if the shrimp stock biomass showed
neither an increment or a decrement, or c) the quota would be increased as compared to
the one set the previous year, if a growth in shrimp stock biomass was detected. Again,
this recovery strategy is based on the rationale of controlling the annual catch of this
fishery, from one year to another, aimed at maintaining the stock biomass at a level,
which maximizes its yield. Moreover, a catch quota should be selected in such a way that,
while the fishery operates at acceptable economic levels as assessed by the involved
parties themselves, that it would lead to a steady recovery of the stock biomass. Finally, it
REBUILDING PLANS IN MEXICO – 31
REBUILDING FISHERIES © OECD 2012
is suggested that multiple (biological, social and economic) objectives should be
considered in any future fishery recovery plans (Díaz-de-León and Seijo, 1992).
Overview of issues
No rebuilding plan has been developed yet.
The Campeche Sound pink shrimp fishery is currently the major economic activity of
the after the oil industry and therefore the crisis in this fishery generates into an economic
crisis at this area (Arreguín-Sánchez et al., 2008b, p. 91). There are two main factors that
can be pointed out as important when developing a rebuilding plan, namely the social and
economic considerations. Moreover the environmental changes detected at the Campeche
Sound should also be considered as additional factors that need to be taken into account
when developing such a plan.
Institutional Framework
Legislation – Authority
In Mexico, the “Ley General de Acuacultura y Pesca Sustentable” (LGAPS, or the
General Law on Sustainable Fishing and Aquaculture) regulates the access, use and
management of the fishery resources. The authority responsible for the enforcement of
this legislation is a Secretariat called SAGARPA (or “Secretaría de Agricultura,
Ganadería, Pesca y Alimentación”); to this end, two administrative bodies of SAGARPA,
the INAPESCA (“Instituto Nacional de Acuacultura y Pesca”), and the CONAPESCA
(“Comisión Nacional de Pesca y Acuacultura”) undertake several duties and enforce the
regulations, as stated at the LGAPS, on fishing and aquaculture. The former is in charge
of coordinating and leading the scientific and technical research on fishing and
aquaculture but also for devising and updating the National Fisheries Charter (NFC). The
latter is the body in charge of executing technical recommendations pointed out by the
former; issues the fishing permits and fishing concessions based on the management
regulations set by the NFC and, whenever a boat or fisher is found with fish products
outside the authorized fishing season, it has the authority to confiscate it. When issuing
fishing permits, CONAPESCA uses the management regulations set by the NFC.
The pink shrimp fishery is regulated through the Norma Oficial Mexicana, NOM-
009-PESC-1993 (DOF, 1994) and its amendments from 1997 (DOF, 1997) which
contains regulations on minimum size by shrimp species, closed seasons, as set yearly by
INAPESCA, and closed areas. There is also a consultative body wherein the management
regulations for every shrimp fishing season are discussed, namely the National
Committee of Fisheries and Aquaculture (or “Comité Nacional de Pesca y Acuacultura”).
This Committee is composed of the stakeholders in the shrimp fisheries, which meet
before the opening of the fishing seasons. During the meeting, the Committee introduces
and discusses issues on the various shrimp fishery parameters, as estimated by
INAPESCA´s staff, as well as on the recommended policies for the next fishing season
(Hernández and Kempton, 2003). Hernández and Kempton (2003) report that during the
meetings, not all the stakeholders seem to be well informed or aware of the many
technical aspects related to the shrimp fishery. Thus, those authors suggest that some of
the stakeholder participants on shrimp fishery meetings seem to be in need of training to
assist them in understanding long-term pros and cons of shrimp fishery decision-making.
Finally, specific regulations concerning fisheries in natural protected areas (NPA), have
to be observed.
32 – REBUILDING PLANS IN MEXICO
REBUILDING FISHERIES © OECD 2012
Relevant policies and guidelines and (brief description)
Article 36 of the Sixth chapter of the Fishing Law (LGAPS) states that the
instruments for fishery policy are the following: 1) the programs on fishing plans
(ordenación), 2) the fishery management plans, and 3) the concession or granting.
Besides, Article 36 also states that: “the authorities will promote and support the
introduction of any control mechanism set by resource users themselves, backed up on
their traditional knowledge on local system management. They will also promote the
creation of community groups which assist in protection and management of the fishing
resources based upon the guidelines set at the LGAPS”. Hence, these policies should
assist in agreeing upon and designing a fishery recovery plan to the Pink shrimp fishery.
The current Fishing Law or LGAPS also encourages a change from the centralized
(top-down) system of fisheries management, to passing many of these duties either to the
state or to the “municipios” (in the case of demersal fisheries). Thus, given the social
importance of some fisheries, several states, like Campeche and Yucatan, do have their
own Fisheries Secretariat. Thus, for the pink shrimp stock recovery plan to be cost-
effective, a coordinated action needs to be agreed upon among the three levels of
government (municipal, state, and federal). Lessons can be learned from the the red
grouper fishery (see the second Mexican case study). However, if in the short and
medium runs, a reduction in fishing effort is needed for this fishery to recover, some
policies to back up this reduction need to be put in place. For example, currently there is a
policy to reduce the fishing effort through boat or vessel voluntary retirement (or “retiro
voluntario de embarcaciones”). This policy is being applied in both, the Pacific and Gulf
of Mexico shrimp fisheries (CONAPESCA, 2010). According to this policy, from 2005 to
2009, 147 shrimp vessels (with their respective fishing permits) were voluntarily retired
from the Gulf of Mexico.2
Moreover, an inter-sector analysis of the region needs to be taken into consideration.
In particular, the region as a whole (the Campeche Sound) should be examined and
focused on potential productive sectors wherein new jobs or small business could be
created for retired fishers. Finally, another aspect that should be taken into consideration
in the recovery plan is a better control of the “free fishers”.
Institutional changes that resulted from the implementation of the rebuilding plan
No rebuilding plan has been set yet.
Fisheries Rebuilding Plan Framework
Management response
No rebuilding plan has been set yet and therefore no management changes could be
described. Nevertheless, some desired changes are briefly described in the following
paragraphs.
Better coordination among the three government levels (municipal, state and federal)
based on the political will to recover this fishery is an important part of a rebuilding plan.

REBUILDING PLANS IN MEXICO – 33
REBUILDING FISHERIES © OECD 2012
This coordination needs to be a part of the Fishery Council from Campeche State
including the participation of neighbouring coastal states.
On the side of the fishers, a desired management response would be that they could
actively participate in observing the management rules.
Controls could be made by using the comparison of the stock biomass, from one year

fishery.

Monitoring and enforcement
No rebuilding plan has been set yet and therefore no monitoring and enforcement has
been undertaken. However, some desired monitoring and enforcement are briefly
described in the following paragraph.
Similarly to what has been described for the other Mexican case studies with no stock
recovery plan, once the objectives of a recovery plan are set, the government,
i.e. CONAPESCA, would be in charge of the monitoring and enforcement of rules. To
34 – REBUILDING PLANS IN MEXICO
REBUILDING FISHERIES © OECD 2012
complement CONAPESCA's enforcement, fishers and interested stakeholders should
participate too, but they need to devise their own monitoring program. In this respect,
fishers from Campeche could learn from the several successful experiences on fisheries
co-management occurring elsewhere. To this end, the fishers would need to organize
themselves to get funding to implement their own monitoring program.
Performance measurement and evaluation
The CONAPESCA, assisted with technical support from INAPESCA, is the
institution in charge of evaluating the success of the management, and in this case of the
stock recovery of any marine species. Additionally, the fishers and other stakeholders
should also participate in the evaluation of the progress of the stock recovery. Even with
no recovery plan yet, it the emerging management regulations established during the
1990s, namely the latest amendments done to NOM 009-PESC-1993 (DOF, 1997) has,
albeit slightly, stabilized the past pink shrimp biomass decline (INAPESCA, 2006,
p. 466).
In terms of using variables for the evaluation of the plan, as previously stated, once
the recovery plan is set, the pink shrimp fishery would have its stock biomass compared,
from one year to the next one, as the indicator to measure the recovery performance. In
addition, other indicators based on economic, social and institutional criteria should also
be used. In particular, it would be necessary to undertake a bioeconomic analysis to this
fishery and, based on the results, the average net return per trip could be used as another
indicator to measure the performance of this fishery.
Economic Aspects
In Mexico, the shrimp fisheries, together with several other semi-industrial and
industrial fisheries, with a total of 2 215 vessels, receive partial fuel subsidies. In
particular, from 2003 to 2009, a total of MXN 5 200 000 000 (about EUR 305 882 353)
have been paid out as subsidies to the aforementioned vessels (CONAPESCA, 2009). Of
this amount, 50% has been delivered to the shrimp fishing fleets from both, the Pacific
coast and from the Gulf of Mexico. In 2009, a total of 1,443 registered trawling shrimp
vessels received MXN 520 000 000 (about EUR 30 588 235.30) as a fuel subsidy
(CONAPESCA, 2009).
According to CONAPESCA (2009), with this subsidy, the Mexican government is
assisting the shrimp fishing fleets because, it is argued, they are coping with an economic
crisis derived from tree main factors, namely a decline in the price of shrimp at
international markets, the steady increment of the gas used in Mexico to pursue fishing,
and because, given that the majority of the shrimp vessels are quite old, they are
inefficient in capturing shrimp.3 (see). Nevertheless, the Mexican government also is
interested in assisting the shrimp fishing fleet with funds to modernize or substitute old
vessel by new ones (CONAPESCA, 2009; FIRA, 2009).
With respect to the economic importance of pink shrimp, it is an export product for
which main the market is the United States. According to FIRA (2009), 95.3% of the
national Mexican shrimp production was exported to the United States in 2008. During
the last decade, the price of shrimp has declined in international markets and this has
severely affected Mexico´s fishing sector. This decline was due to an increase in the
3 www.conapesca.sagarpa.gob.mx/wb/cona/10_de_enero_de_2009_mazatlan_sin
REBUILDING PLANS IN MEXICO – 35
REBUILDING FISHERIES © OECD 2012
world production of shrimp, primarily from aquaculture. For example, in the year 2000,
Mexican shrimp prices –U15, U15/20, and U21/25 peaked (USD per lb) at 7.4, 6.8, and
6.5 respectively, whereas in 2006, they reached, respectively, USD per lb) 5.0, 4.3, and
4.2 (FIRA, 2009, p. 39).
Economic analysis in the design stage of the rebuilding plan
There is no design stage of the rebuilding plan yet. Despite the pink shrimp fishery is
recognized as a major economic activity after the oil industry, we found no specific
bioeconomic analysis undertaken for this fishery. When designing a recovery plan to this
fishery, a trade-off between social (generation of jobs) and economic criteria should be
made, based on the premise of sustainability.
An analysis based on market measures should be considered at the time of designing
the recovery plan. Among these measures are: the size of captured shrimp (compared
against the sizes that are required by the markets); and the transferable property rights of
the granting (or “concesiones”) of the “Industriales” or “Armadores”, a permit that can be
sold in commercial transactions. In contrast, if the current legislation dealing with
cooperatives is left unchanged, the cooperativist fishers would continue being ruled by
their rules and norms (i.e., a cooperativist right or title can’t be sold but only passed down
or inherited, from a father/mother to his/her descendants).
Similarly to what was commented in the previous reviewed case studies, one indicator
of economic success would be a gradually increasing value of the catches.
No alternative timeframes, measures or strategies have been considered or assessed
for this fishery yet.
Rebuilding efforts as they have affected the fishing industry
As many artisanal fishers do not have their corresponding fishing permits, we will

Social Aspects
Key stakeholders affected by the rebuilding plan and their respective interests
There are no stakeholders affected by any rebuilding plan yet; however, a description
of current users of this resource, as potential affected people, is briefly described in the
following paragraphs.
According to INAPESCA (2006), the Mexican pink shrimp fleet, owned by
entrepreneurs, started its operation in 1949, the very year during which the Mexican
government assigned the property rights of the shrimp fisheries to members of the fishing
cooperatives. In turn, Mexican fishing cooperatives were not formed until 1966, a year
when they claimed their common property resource, resulting in a contract (or “Contrato
de Uso de Embarcaciones Camaroneras”) signed between entrepreneurs and fishers to
allow the latter the use of the shrimp vessels. After several years and amendments to
those contracts, the Mexican government decided to transfer (i.e., to first buy and then
give through credit) the shrimp fleet to the social sector (or to fishing cooperatives) in
1982. However, due to the liberalization of markets and related global policies, changes
in the Mexican Fishing Law (LGAPS) in 1992, allowed sectors, private and social, to get
into or to invest in any fishery of their interest, including shrimp. Therefore, currently
both, entrepreneurs (locally called “Armadores”) and the social sector do form (own) the
pink shrimp fleet.
A total of 290 artisanal boats with outboard motors are currently registered in
Campeche and Tabasco states (247 in Campeche, and 43 in Tabasco), which are members
of fishing cooperatives; to this must be added an unknown number of outboard motor-
boats from the northern portion of Yucatan, and an unknown number of free fishers.
The industrial fleet is located at the Campeche state although some vessels from
neighbouring states also use to fish pink shrimp at the Campeche Sound.
At the end of the 1970s, the industrial fleet numbered of around 800 vessels, which
were located at both, Ciudad del Carmen and Campeche city. According to INAPESCA
(2006) and to Navarrete del Proó (unpublished), by the end of 2000’s this fleet had
decreased by nearly 50%. Currently, there are a total of 252 vessels registered in
Campeche state; 122 of them being registered in Campeche city and the remaining
registered at Ciudad del Carmen (INAPESCA, 2006). The industrial fleet is relatively old
and hence it is not considered to be efficient in catching shrimp. In particular, about 71%
of the fleet based at Campeche city is between 19 and 33 years old. The majority of the
fleet based at Ciudad del Carmen is between 10 and 20 years old.
Both the fishing cooperatives and the “Armadores”, want to sell their shrimp product
on international markets and would probably both be interested in participating in a
formal shrimp stock recovery plan.
The oil industry, based in the Campeche Sound, shares the area with the shrimp
fishers. The fisheries and the oil industries do have competing interest that would need to
be addressed at higher political levels.
Stakeholder participation in the design and implementation of the rebuilding plan
Given the steady decline in stock biomass of this species, both the fleets involved
asked INAPESCA and local authorities to meet with stakeholders to examine and discuss
the current status of this fishery. This resulted in local gatherings including all involved
REBUILDING PLANS IN MEXICO – 37
REBUILDING FISHERIES © OECD 2012
sectors held in the years 1994 and 2000 (Arreguín-Sánchez et al., 2008b). The first year
in which a closed season was implemented was in 1994 but as the stock decline continued
in the following years, the closed season was lengthened (since 1998) to first two and
then to five months (May to October) during 2001-2003.
As previously stated, according to INAPESCA, the above management regulations
are commonly discussed and negotiated with the interested parties; that is the
cooperativist fishers, “Armadores”, government, and scholars. There is little doubt that
these people will be willing to continue their participation in designing a stock recovery
plan, as well in the negotiation of any future TAC.
Equity or distributional issues raised as a result of the implementation of the
rebuilding plan
No information was found on any equity or distributional issues for this fishery.
Compensation mechanism used in support of rebuilding measures
No compensation mechanisms associated to any recovery plan were found.
Implementation Issues & Lessons Learned
Key institutional and policy challenges faced
No rebuilding plan has been implemented yet; however, in the next paragraphs, we
will describe about the emergent management actions implemented since the pink shrimp
fishery was declared in crisis, in 1994.
Despite a lack of formal document or an implicit strategy entitled as rebuilding or
recovery plan for pink shrimp, some management actions including a consulted closed
season were implemented which, altogether are perceived as a genuine will of
stakeholders to halt the fishery collapse. Thus, these management actions could be
considered as the baseline in devising a stock recovery plan to this fishery.
The first issue to address is the effective communication among stakeholders. Thus,
during the implementation of the recovery plan to this fishery, the challenges faced could
be along the lines of reaching effective communication among stakeholders; therefore,
participatory workshops could be undertaken to dissipate mistrust. Moreover, in assessing
the stock and setting the catch quota, all procedures used should be clear to all involved
parties. Finally, the evaluation and performance measurement of stock recovery should be
clear to all stakeholders. In summary, given the social and economic importance of the
pink shrimp fishery, enforcement of management rules undertaken solely by the
government would hardly be cost-effective. In this respect, government and the academia
should seek collaborative work (government-resource users) to help with fisheries
management, especially in the artisanal fleet. Thus, if this goal could be, to some extent,
reached, it would have a form of co-management.
Lessons learned
The pink shrimp fishery in the Campeche Sound was the second most economically
important activity after the oil industry. A gradual and steady decline of catches led to
firstly, an acknowledgement that the fishery was coping with a crisis and secondly, that
new management actions were needed to halt the collapse of the fishery. To this end the
38 – REBUILDING PLANS IN MEXICO
REBUILDING FISHERIES © OECD 2012
government and the corresponding consultative bodies imposed closed seasons to protect
the reproductive stock of this species.
Lesson learned include:
It is currently known that the recruitment of the pink shrimp stocks has been gradually
decreasing since the end of 1970s; hence, the uncertainty related to environmental changes
affecting the recruitment process in this species would be one of the major factors affecting any
recovery of this fishery. However, the causes of this diminishing recruitment, either natural or
man-made (e.g., oil spills), should be further studied as to have a better understanding of the
changes that are having place in the Campeche Sound.
Based on the new management regulations set in 1994, there seems to be political will to
discuss and devise a recovery plan to this fishery. To this end, one of the first challenges will be
along the lines of reaching effective communication among stakeholders.
The recovery plan should not be based solely on biological grounds. The objective of the plan
should be more wide ranging, including social and economic criteria, taking sustainability into
consideration.
Another challenge is to review and then control the total number of boats (both legal and
illegal) and industrial vessels participating in this fishery.
Given the high costs of enforcement in fisheries, the recovery plan would need to be
legitimated by the resource users themselves, with participatory research, monitoring and
enforcement and, in general, with characteristics of co-management.
Should a reduction in the fishing effort be necessary, the program on voluntary retirement of
boats, together with an evaluation of it, should continue Also a policy on old vessels
decommissioning should be implemented. Moreover, a part-time job program or similar
policies could be devised to assist fishers who are willing to both, observe the new management
rules as well as to those which voluntarily choose to retire from the fishery.
The NFC should be updated, i.e., it should include the explicit government effort to recover the
fishery as well as a brief summary of results obtained with the stock recovery scenarios run by
scholars; and

The Queen Conch Fishery in Mexico
General Information
The queen conch (Strombus gigas), a large gastropod (>15 cm siphonal length) was,
for several decades, together with other nine gastropod species, the main resource basis of
an open access artisanal fishery. The fishery was located from the Gulf of Mexico, more
specifically from Veracruz’s reefs, to the Mexican Caribbeanalong the Quintana Roo’s
coasts (Sosa-Cordero et al., 1997; Basurto et al., 2000). It was not until 1987 that an
official allocation of catch quota to this fishery was decided upon (INP, 2000). However,
several factors including a notably uncontrolled illegal fishing, resulted in depleted queen
conch's stocks and therefore in a progressive contraction of its commercial geographical
range at the Caribbean, until this species was listed in CITES’ red list, Appendix II, as a
“Commercially threatened” species (Shawl and Davis, 2004). In Mexico, fishery statistics
data for this and many gastropod species are fragmented or lacking, but there is a
maximum catch record of 450 tonnes for queen conch in the year 1979 (INP, 2000).
Given the depleted status of queen conch stocks, since 1987, an indefinite fishery
closure for this species was implemented at Yucatan State, although illegal fishing has
been reported to still take place at some coastal areas, especially at “Arrecife Alacranes”
(Aldana-Aranda et al., 2006). Nevertheless, regional research institutes from Yucatan are
already working on educational programs to raise awareness on the ecologic and
economic importance of this species (see Aldana-Aranda et al., 2006).
Currently, the Mexican fishery is split up, with the first fishery catching nine
gastropods, in which queen conch no longer forms part of its landed catch, being located
at Campeche’s coasts and a second fishery, based primarily on catching queen conch,
located at Quintana Roo’s coasts, particularly at an atoll-like called “Banco Chinchorro”
and at Cozumel Island.
Queen conch’s muscle is used for human consumption and its shell is used for
handcraftsIt is used as an ingredient in a traditional and much demanded dish in the
coastal communities and in at restaurants of Quintana Roo. However, a steady
diminishing abundance of this species had occurred during several decades resulting in
depleted stocks This resulted in lowering of the catch quota so that in 1993, the quota for
this species was set at only 45 tonnes, and 21 t in 2008 (Sosa-Cordero, unpublished data,
2009).
In 2009, only 37 boats with outboard motors were recorded being engaged in this
fishery. The TAC is fished using two methods; skin diving at Banco Chinchorro, and
SCUBA at Cozumel Island. In both cases, specimens are captured by hand (Basurto et al.,
2000). Nevertheless, given that there are serious difficulties in the enforcement of fishing
rules, the fishery has many other occasional users as well as permanent free fishers
(“pescadores libres”) who do not form part of entitled fishers.
The management measures include a minimum size, an annual catch quota and a
closed season. Moreover, the National Fisheries Charter (NFC) portraits this fishery as
deteriorated and sets its Target Reference Points as 0.10 individual/m2 to Banco
Chinchorro and as 0.04 individual/m2 to Cozumel Island (DOF, 2006, p. 28).
REBUILDING PLANS IN MEXICO – 41
REBUILDING FISHERIES © OECD 2012
Species
Two gastropod species, the queen conch (Strombus gigas), and the white conch
(Strombus costatus) form the resource base of this fishery, with the former comprising
around 95-98% of the catch (DOF, 2000, 2004). According to Basurto et al. (2000), until
1986, other gastropod species, including Pleuroploca gigantea, Turbinella angulatus, and
Busycon contrarium formed part of the Quintana Roo’s queen conch fishery with
corresponding shares in the landed catch. However, no recent studies were found to
confirm whether these species are still a part of this fishery.
Fishing Area(s)
The queen conch´s fishing grounds for an artisanal fishery at the Mexican Caribbean
are located in Banco Chinchorro, an atoll-like arrecifal complex approximately 814 km2
located south of Quintana Roo (Figure 9.4). Banco Chinchorro was decreed as a
Biosphere Reserve, in 1996. Whenever densities of queen conch are enough to support a
certain level of fishing mortality (as evaluated by INAPESCA´s biological surveys),
commercial fishing has been allowed to commence at the continental shelf located north
of Cozumel Island (Figure 9.4).However, in 1990, monitoring of this species abundance
resulted in the setting of a closed season, which has been occasionally re-opened. In
general, this fishery operates at depths of 2-15 m at Banco Chinchorro wherein skin
diving is used, and at depths of 25-32 m, using SCUBA, at Cozumel Island (Basurto
et al., 2001).

42 – REBUILDING PLANS IN MEXICO
REBUILDING FISHERIES © OECD 2012
Timeframe for rebuilding plan
No timeframe for its rebuilding has been set yet (but see sections 1.5 and 1.6, below).
Major identified sources of mortality/threats to rebuilding
Fishing mortality, primarily due to illegal fishing, is considered to be the main cause
of queen conch’s mortality (Sosa-Cordero, 1994; Sosa-Cordero et al. 1997; Basurto et al.,
2001; 2005) and therefore, as a main threat to any potential rebuilding plan. Illegal
fishing results in double negative consequences to queen conch On the one hand it makes
useless the management regulations in place (i.e., closed season, minimum size, and catch
quota) because their effectiveness and adequacy can not be systematically and objectively
evaluated On the other hand it also causes disappointment among cooperative fishers with
fishing permits who abide by the management rules, with regards to the others that do not
abide to the law (Thomassiny-Acosta, 2010; Sosa-Cordero, personal observation). Indeed,
people who are caught pursuing illegal queen conch fishing are able to, can easily avoid
heavy sentences if they pay a quite modest infraction fee. Therefore, many fishers argue
that there are no incentives for them to observe the queen conch's management rules
(Thomassiny-Acosta, 2010).
Other aspects which should be considered include the status of queen conch habitats
or seagrass meadows which are being negatively affected due to a rapid expansion of
Quintana Roo’s tourism industry (Alvarez-Legorreta, personal communication, 2008;
Thomassiny-Acosta, 2010).
Rebuilding goal/target (MSY, MEY etc.)
No explicit rebuilding goal has been set to queen conch yet. However, in terms of its
management, currently the NFC does not allow an increment of the fishing effort on
Quintana Roo’s queen conch fishery (DOF, 2006). Moreover, the NFC also sets Target
Reference Points to 0.10 individual/m2 for Banco Chinchorro and 0.04 individual/m2 for
Cozumel Island (DOF, 2006, p. 28). The Centros Regionales de Investigación Pesquera
(CRIP or Regional Centre for Fishery Research), belonging to INAPESCA, are in charge
of the biological surveys used to set the annual catch quota to this and to most other
commercially exploited species. Additionally, and similarly to what has occurred for the
red grouper fishery (see the second Mexican case study) the CRIP’s staff, has for several
years now worked on stock assessments scenarios – undertaken as academic exercises
but also as potential information to be delivered to INAPESCA whenever required to
recover this fishery. Thus, for instance, Basurto et al. (2000) report that queen conch´s
Target Reference Point should be around 500 tonnes, and assess that this target would
correspond to 70-100 Kg of queen conch (muscle) per fishing trip; as well as to an annual
catch of 45 tonnes, and to a total fishing effort of 12-15 days per year (Basurto et al.,
2000).
However, a systematic, yearly assessment that is fully taken into account by the CRIP
is the annual catch quota (TAC) for this species. Two procedures are used to set this
quota The first procedure is ad hoc and consists in that once the assessment of adult’s
stock biomass has been completed, a catch quota is set in such a way that only half of the
estimated stock should be harvested (Basurto et al., 2007; 2008; 2009). The second
procedure is based on biological grounds andt consists in estimating differences between
the current adult observed density (in m2) at the fishing area and a known minimal adult
density of 0.0048 individual/m2 needed for queen conch to potentially complete a
reproductive cycle (based on Stoner and Ray-Culp, 2000). Based on this criteria and
REBUILDING PLANS IN MEXICO – 43
REBUILDING FISHERIES © OECD 2012
using the distribution area (in Km2) of this species, a surplus biomass is estimated which
corresponds to a catch quota (Basurto et al., 2007; 2008; 2009).
Overview of issues
No rebuilding plan has been developed for this fishery yet. However, the fact that
although no official or formal documents issued by the federal government have
addressed or stated any will to recover the queen conch fishery this contrasts with an
explicit local will to recover the fishery. Given that in several regional workshops
undertaken to design Banco Chinchorro’s management plan, local fishers and the private
sector have asked local authorities to set up a strategy to eradicate illegal fishing on queen
conch and thereby allow it to recover (Arce-Ibarra, 2008, personal observation). This will
is coincident with the opinion of the Banco Chinchorro Biosphere Reserve's staff (from
the Minister for Environment or SEMARNAT-CONANP) as well as with local CRIP`s
staff in using recovering scenarios for this species. In addition, there are other cultural
factors related to queen conch which seem to be important to local people. An example is
the fact that this species forms part of Quintana Roo’s flag, representing an icon of
identity and livelihood to coastal communities.Currently, several coastal communities of
Quintana Roo have tourism and fishing (based primarily on queen conch and spiny
lobster), as their major livelihoods (Thomassiny-Acosta, 2010). Unfortunately, the fact
that queen conch is distributed at relatively shallow transparent waters (2-32 m depth) and
as this species moves very slowly, makes it vulnerable for illegal fishing.
Institutional Framework.
No rebuilding plan has been devised yet.
Legislation – Authority
In Mexico, the rules to access, allocate and manage the fishery resources are set by
the “Ley General de Acuacultura y Pesca Sustentable” (LGAPS, or the General Law on
Sustainable Fishing and Aquaculture). The authority responsible for the enforcement of
this legislation is a Secretariat called SAGARPA (or “Secretaría de Agricultura,
Ganadería, Pesca y Alimentación”); to this end, two administrative bodies of SAGARPA,
the INAPESCA (“Instituto Nacional de Acuacultura y Pesca”), and the CONAPESCA
(“Comisión Nacional de Pesca y Acuacultura”) undertake the several duties and enforce
the regulations, as stated at the LGAPS, on fishing and aquaculture. The former is in
charge of coordinating and leading the scientific and technical research on fishing and
aquaculture but also in devising and updating the National Fisheries Charter (NFC), the
main instrument used in the management of fisheries. In turn, CONAPESCA is the
institution in charge of executing any technical recommendations pointed out by the
former; issuing fishing permits and fishing granting based on the management regulations
set at the NFC and, whenever a boat or fisher is caught with fish product outside the
authorized fishing season, it has the authority to take confiscate it. Note that in issuing the
fishing permits, CONAPESCA uses the management regulations set at the NFC, and for
this very reason the NFC needs to be updated.
To help with management, the Mexican government has also devised an instrument
called Normas Oficiales Mexicanas (NOMs) used primarily to regulate the most
economically important fish resources. Queen conch is acknowledged as a valuable
resource, therefore the NOM which sets the management regulations on this species -such
as a minimum size of 20 cm total length, and introduces the two approved methods for
44 – REBUILDING PLANS IN MEXICO
REBUILDING FISHERIES © OECD 2012
capturing this species, SCUBA and skin diving, is controlled by the NOM-009-PESC-
1994 (DOF, 1995). This is complemented by a fishing agreement (“acuerdo de pesca”)
specifying a closed season of eight months (currently changed to eleven months), and
several closed areas (such as the Gulf of Mexico and Yucatan state) (DOF, 2009). It also
addresses a closed seasons of three years, 2009-2012 to Cozumel Island.
For most fisheries, other complementary activities on fisheries management are
undertaken by both, the SEMARNAT (or “Secretaría de Medio Ambiente y Recursos
Naturales”) and the PROFEPA (or “Procuraduría Federal de Protección al Ambiente”).
However, in the case of queen conch which fishing area is primarily located at a natural
protected area (Banco Chinchorro) it is the SEMARNAT and within it, a Commission in
charge of managing the natural protected areas (or CONANP, “Comisión Nacional de
Areas Naturales Protegidas”) which, in coordination with CRIP's staff approve any
fishing permit issued to fishers working in natural protected areas. The Navy assists all
the aforementioned institutions in monitoring and detecting any illegal activity
undertaken at the sea.
Relevant policies and guidelines
Article 36 of the Sixth title of the Fishing Law (LGAPS) states that the instruments
for fishery policy are the following: 1) the programs on fishingplans, 2) the fishery
management plans, and 3) the concession or granting of licences. Besides, Article 36 also
states that: “the authorities will promote and support the devising of any control
mechanism set by resource users themselves, backed up on their traditional knowledge on
local system management. They will also promote the creation of community groups
which assist in protection and management of the fishing resources based upon the
guidelines set at the LGAPS”.
From the previous paragraph, it is noteworthy that, except for point 3), queen conch
has been not subject to the other ruling instruments. However, based on the contents of
Article 36h, the federal institutions in charge of fishery management could benefit
fromlocal community groups` organization in the design of a recovery plan for queen
conch.

There are temporary area closures for the queen conch fishery (the fishing areas from
Yucatan state and most recently, Cozumel Island) but they are not a part of a formal stock
recovery plan.
Since the mid 1990s, several scientists have conducted research on culturing Queen
Conch (e.g. de Jesús-Navarrete et al., 1996). The government provided the required funds
to undertake research through its National Science and Technology Council (CONACyT)
as well as through the former Ministry of Fisheries (“Secretaría de Pesca”) and their
results were spread among the scientific community but less among the resource users
and the government. Despite this, although the aquaculture efforts for queen conch have
not resulted in any stock enhancement and replenishment programs yet, it could easily be
incorporated in any future stock recovery plan.

Monitoring and enforcement
No rebuilding plan has been developed to this fishery yet. Therefore, the only
monitoring that will be described will be one of any standard fisheries management plan
(as set at the NFC).
With respect to the monitoring of any fishery stock, it is undertaken by the
CONAPESCA that has the responsibility of monitoring that the administrative and
regulatory measures are observed.
In many fisheries, the cooperative fishers do have their own monitoring programs but
in the case of queen conch, a fishery which is knownto have a relative high number of
free fishers (“pescadores libres”) no such programs are known to exist.
Performance measurement and evaluation
No rebuilding plan has been developed to this fishery yet.
The CONAPESCA, assisted with technical support from INAPESCA, is the
institution in charge of evaluating the success of the management of a fishery. Currently,
the queen Conch fishery has only one indicator to measure any increment in stock
biomass, namely the density of this species by area (individual/m2) as assessed through
biological surveys. Unfortunately, the current criteria used to set the catch quota for this
species are based solely on biological grounds, leaving out other economic, social and
institutional aspects.
Economic Aspects
Despite queen conch being a valuable resource, the fact that this species is listed on
CITES’ Red List, as a “Commercially threatened” species (UNEP, 2010) restricts its
export because CITES states that export permits should only be issued when the national
authority has deemed that the export will not be detrimental to the survival of this species
(Meddley, 2008). It has been estimated that the annual queen conch production from the
whole Caribbean is worth around USD 60 000 000 (approximately EUR 42 352 941)
(CITES, 2003). From 1992 to 1998, Caribbean`s queen conch production ranged between
6,519,000 and 7,369,000 Kg. However its annual production only reached up to
3,131,000 Kg in 2001 (CITES, 2003).
Prices for queen conch from the Caribbean region usually ranges from USD 3.0 to
8.0 per Kg (approx. EUR 2.1-5.6) but in some countries, like in Martinica and
Guadaloupe, it reaches up to 11.0 US Dollars per Kg, for local meat, and up to 20.0 US
dollars per Kg for imported meat (CITES, 2003). In Quintana Roo, Mexico, this species
is being sold by the fishing cooperatives at USD 76.40 pesos per Kg (about 4.5 Euros per
Kg). It is only sold fresh and is essentially a product for local consumption, in particular
at both, local and touris restaurants. For several years, Mexico had occupied the fifth
place in queen conch’s production in the Caribbean, and during the year season 1996-
1997 its production value reached about MXN 2 000 000 Mexican pesos (about
EUR 117 647) (INP, 2000).
The following table shows Quintana Roo’s official statistics and its corresponding
values for the years 2000 to 2008.

Use of economic analysis in the design stage of the rebuilding plan
No rebuilding plan has been devised yet.
Market-based measures
No information was found to address this question. However, a note on transferable
fishing property rights is relevant here. The Fishing Law (LGAPS) states that the granting
(or “concesiones” –lasting 25 years but with a potential of renewal by another 25 years),
could be sold. Nevertheless, in the case of queen conch, which has the cooperative fishers
as the de facto users, such a transaction would not be allowed because any interested
people on a aving such a right would need to become an entitled cooperative fisher before
buying it, and, a cooperative right or title can’t be sold but only passed down or inherited,
from a father/mother to his/her descendants.
Rebuilding efforts as they have affected the fishing industry
As there are a relatively high number of free fishers associated to this fishery, no

Social Aspects
Key stakeholders affected by the rebuilding plan and their respective interests.
As there is no rebuilding plan in place, there are no stakeholders affected yet.
However, a description of current queen conch’s stakeholders is presented below.
Since 1981, the queen conch fishery was “informally” (i.e. no document was signed)
assigned to fishers grouped into fishing cooperatives and hence, at that time, it became a
de facto common property resource. Nevertheless, the Fishing Law of 1992 changed all
Mexican fisheries status from common property resources to be open for investment to
any group or organization interested in any of them. In this case, investment was open to
private and social (i.e. social organizations or groupings of any type) sectors. Currently,
with the exception of recreational fishing, the Mexican Fishing Law allows both private
and social sectors to enter or invest in any fishery, including the queen conch fishery.
However, as it occurs with most of the valuable fishing resources, like queen conch, they
have already a relatively high fishing pressure or are in a deteriorated status Therefore the
private sector has shown little interest in investing in such fisheries. For some resources,
like shrimp, the private sector invested in aquaculture. That has not been the case for the
queen conch.
At the end of the 1990s there were about 100 entitled fishers at Banco Chinchorro
plus 50 more registered in Cozumel Island cooperatives, using 73 registered outboard
boats (INP, 2000). However, at present, and given its deteriorated status, the queen conch
fishery is being pursued by only 89 fishers using 37 outboard motor boats all belonging to
three fishing cooperatives operating at Banco Chinchorro (Sosa-Cordero, unpublished
data, personal communication from the heads of the fishing cooperatives, 2009). Other
cooperative fishers had been participating in this fishery, particularly from Cozumel
Island, but they stopped fishing in 2004 due to the very low abundance of this species as
well as because closed season had been declared for some of their fishing grounds.
Other competing users or stakeholders include an unknown number of artisan women,
located at several coastal communities of the Yucatan Peninsula who use the shell of this
species to make hand crafts (such as lamps made of the whole shell; earrings, necklaces).
Two groups of these women have been met by local scientists, one at the community of
San Felipe, Yucatan (Arce-Ibarra, unpublished data, personal observation, 2006) and
another at the community of Xcalak, Quintana Roo (Thomassiny-Acosta, 2010; Arce-
Ibarra, unpublished data, personal observation, 2010). Their arts and crafts are sold
primarily to tourist and form a part of their income (Thomassiny-Acosta, 2010).
Another group of stakeholders are the free fishers, an aspect that the Mexican
government needs to address in a more integral (i.e., seeking to diversify their livelihoods
or offering job opportunities at alternative productive sectors) way. Finally, it is not clear
how many people depend directly and indirectly from the queen conch fishery.
Stakeholder participation in the design and implementation of the rebuilding
plan
As there is no rebuilding plan in place, there have not been any stakeholder
participation in designing and implementing any rebuilding plan. However, a comment on
an observed will to recover the queen conch stocks is discussed below.
REBUILDING PLANS IN MEXICO – 49
REBUILDING FISHERIES © OECD 2012
No technical report or formal document have addressed or reported that consultation
or negotiation between the government and fishers when setting the queen conch catch
quota.
For several years several sectors of Quintana Roo's society have, in one way or
another, raised their concerns about the gradual diminishing abundance of queen conch
stocks at the coast. Thus, as previously stated, at the regional workshops undertaken to
review the Banco Chinchorro management plan, the private sector and fishers stressed the
view that local authorities could design improved plans to stop illegal fishing on queen
conch and thereby to allow for the recovery of the stocks (Arce-Ibarra, 2008, personal
observation). Moreover, the owners of local restaurants have also protested whenever,
they claim, queen conch's management rules have been affecting their income because,
they argue, this species is a much demanded dish (Arce-Ibarra, 2008; 2009 personal
observation).
Compared to other fisheries, the group of queen conch fishers is perceived by
Mexican scholars as a group with full awareness of the numerous problems affecting their
fishery and who may help in finding ways to overcome them. In particular, this group has
over 5 decades of interaction with the resource base and they are perceived as people with
an ample local knowledge on the coastal ecosystem where its fishery is located and on the
several issues of legislation on fisheries. They have skills and expertise not only in
capturing queen conch but also in accounting and marketing this and many other fish
species.
Implementation Issues & Lessons Learned
Key institutional and policy challenges faced
No rebuilding plan has been devised for this fishery yet. Despite a lack of formal
acknowledgement by the federal government, for the need of a fishery recovery plan to
queen conch stocks, some isolated management regulations are in place, currently set in
the National Fisheries Charter and at some NOMs which point toward an implicit goal, as
pursued by INAPESCA's staff, to avoid the collapse of this fishery. Additionally a will to
recover the fishery has been expressed by fishers, the private sector and CONANP's staff.
The main obstacle to be faced by any future rebuilding plan is the effect of illegal fishing
of queen conch.
Given the current status of institutions dealing with fisheries management (i.e. lacking
a capacity, in budget and staff, to devise and implement a fishery recovery strategy),
government and academia should seek the participation of regional fishers in devising a
rebuilding plan to queen conch stocks. In this respect, local fishers should also participate
in devising and enforcing their own monitoring systems, as well in biological surveys. No
doubt that the abalone fishery (i.e. the Mexican Case Study Number 1) could be used as a
successful example of how fishers and government ca work together toward the recovery
of fish stocks. Thus, such a collaborative work (government-resource users), if pursued,
would have characteristics of both, participatory research and co-management.

Lessons learned
Institutions in charge of managing Mexican fisheries did not devise, on time, robust
management rules to avoid the current deteriorated status of queen conch and other
gastropod species from the Gulf of Mexico and the Mexican Caribbean. Moreover, as the
catch statistics of this fishery are fragmented or lacking, a thorough stock assessment for
the whole fishery cannot be undertaken.
Lesson learned
It is known that during the 1970s and 1980s, the queen conch was a part of an open access,
regional artisanal fishery, which geographical range has been gradually contracting due to a
diminishing abundance of this and other gastropod species.
Fishing mortality, on which illegal fishing has a major impact, has left queen conch stocks in a
deteriorated condition in such a way that if not controlled, could drive the fishery to its
collapse. Moreover, it is suggested that other environmental and human-derived factors, like
the tourism industry development along the coast of Quintana Roo, have a negative impact on
the queen conch's habitat (i.e., seagrass). This should be explored further.
A mismatch is found between federal, centralized will and local will to devise and implement a
recovery strategy for this species. In addition, there was also a mismatch between an update of
management regulations set at the NFC for queen conch and the criteria used to set the catch
quota. The latter having implicit management objectives related to recovering the stock of this
species.
One of the overarching challenges in devising and implementing a recovery plan for the Queen
conch would be controlling the illegal fishing in what still seems to be an open access fishery.
Moreover, a recovery plan should include international cooperation among some Caribbean
countries. Thus, the challenge is twofold, first, to work locally and, once the recovery strategy
for this species has been legitimated by the resource users, with education on the importance of
Queen conch, participatory research, monitoring and enforcement and, in general, with
characteristics of co-management, managers should proceed to seek international cooperation.
The current management regulations and criteria to set the catch quota for queen conch is
grounded solely on biological objectives. Should a rebuilding plan be devised, it is suggested
that other objectives such as economic and social should be taken into account.
The lessons learned from the recovery strategy for abalone, as well as the research and
management associated to it, could be used in designing a recovery strategy for queen conch.
If the Mexican government be willing to rebuild or recover its deteriorated fisheries, current
fisheries policies need to be reviewed; in particular, a recovery strategy as a policy needs to be
formally incorporated into the fishing legislation; and, a thorough review of the government
capacities and institutions (e.g., infrastructure, budget and staff) needs to be undertaken.
