IMPLEMENTING THE ECOSYSTEM APPROACH TO CAPTURE

FISHERIES MANAGEMENT

THE ISSUEIn recent years there has been a growingawareness that the traditional approach tomanaging fisheries, which considers the targetspecies as independent, self-sustainingpopulations, is insufficient. It is being recognizedthat sustainable use of the world’s living aquaticresources can only be achieved if both theimpacts of the ecosystem on the living resourcesand the impacts of the fishery on the ecosystemare explicitly identified and, as far as possible,understood. It is also being formallyacknowledged that fishers are an integral part ofthe ecosystem and that both ecosystem andhuman well-being must be achieved.

Awareness of the essential interactions betweenpopulations and their biological, physical andchemical environment is not new. As early as1376, a group of fishers from the Thames estuaryin the United Kingdom expressed their concern toKing Edward III of England about the ecosystemimpacts of the wondrychoun, a form of beamtrawl, which they believed would cause "greatdamage of the common’s realm and thedestruction of the fisheries". However, suchtraditional knowledge was frequently overlookedas fisheries grew rapidly in size and efficiencyduring the nineteenth and twentieth centuries andas science-based, quantitative methods weredeveloped as a means of estimating how to adjustfishing power to resource productivity. Using themost readily available data from fisheries, simplesingle-species models became the preferredassessment tool. These models focused allattention on the target resources and on theimpact that fishing removals had on theirdynamics.

The single-species approach is not the onlycause of the widespread inadequacy ofconventional fisheries management regimes.However, the dangers and limitations of treating

fish populations as entirely self-regulating is wellillustrated by examples that include the highlyvariable small pelagic resources of upwellingsystems, the suspected species replacements inareas such as the Georges Bank, and the impactsof riverine and coastal developments on, forexample, salmon, sturgeon and shrimp stocks inmany areas.

POSSIBLE SOLUTIONSFisheries managers and scientists have been slowto respond to the growing evidence that theecosystem should be considered as a whole.Progress has been impaired by the lack of good-quality, relevant data; the poor understanding ofpopulation, ecosystem and fishery dynamics andinteractions; and the absence of a crediblealternative operational management paradigm.The UN Convention on the Law of the Sea ofDecember 1982 does not explicitly provide foran ecosystem approach to fisheries, even thoughits main focus in relation to fisheries is with the"living resources" of the sea and the environment.Nevertheless, it does include some provisionsthat recognize the interdependence of targetspecies with other marine organisms and theirdependence on their environment.

By the time that the FAO Code of Conduct forResponsible Fisheries (the Code) was adopted byFAO members in November 1995, the principlesof an ecosystem approach to fisheries had startedto emerge, including in non-fisheries instruments(such as the Convention on Biological Diversity).The Code reflects this, and includes manyimportant ecosystem considerations that are ofrelevance to fisheries. In the Introduction to theCode, it is stated that: "The Code sets outprinciples and international standards ofbehaviour for responsible practices with a view toensuring the effective conservation, managementand development of living aquatic resources, withdue respect for the ecosystem and biodiversity."Throughout the Code there are references todifferent ecosystem considerations, and Article 6requires states to conserve aquatic ecosystems

(Paragraph 6.1). Paragraph 6.6 advocates that:"Selective and environmentally safe fishing gearand practices should be further developed andapplied ... in order to maintain biodiversity and toconserve the population structure and aquaticecosystems" while Paragraph 7.2.2 specifies thatmanagement measures should provide for, amongmany other factors, conservation of biodiversity,consideration of environmental impacts andminimization of deleterious impacts, such aspollution, discards, catch of non-target speciesand impacts on associated and dependentspecies. Effective adherence to these and otherprovisions of the Code would go a long waytowards very effective implementation of anecosystem approach to fisheries (EAF).

The holistic foundations of the Code werefurther boosted by the Kyoto Declaration madeby the 95 country delegations that met in Kyoto,Japan, from 4 to 9 December 1995 for theInternational Conference on the SustainableContribution of Fisheries to Food Security. Thesecountries declared that they would "base policies,strategies and resource management andutilization for sustainable development of thefisheries sector on the following: i) maintenanceof ecological systems; ii) use of the best scientificevidence available; iii) improvement in economicand social well-being; and iv) inter- andintragenerational equity", thereby explicitlylinking maintenance of ecological systems withfisheries and fisheries management.

The ecosystem approach to management of theoceans and their resources was consolidated inAgenda 21. Review and coordination of theimplementation of these aspects among UnitedNations agencies was facilitated by the nowdissolved Sub-Committee on Ocean and CoastalAreas (SOCA) of the Inter-agency Committee onSustainable Development (IACSD), operatingunder the umbrella of the UN AdministrativeCommittee on Coordination (ACC).

At its Ninth Session in July 2000, SOCAconsidered the need to improve coordination andsynergies between regional organizations forfisheries and those for the marine and coastalenvironment. It concluded that both types ofbodies could regard the challenge posed by thedevelopment of ecosystem approaches to

fisheries management and integrated coastalmanagement as a potential platform for practicalcooperation.

As a first step in this direction, it was agreedthat a paper centred on ecosystem-basedmanagement in fisheries would be developedjointly by FAO and the United NationsEnvironment Programme (UNEP) and wouldserve as the basis for potential cooperationamong competent regional organizations. Thepaper summarizes the work that regionalorganizations have undertaken in relation toecosystem-based management, outlines possiblemechanisms for cooperation, and identifies issuesfor further consideration. It was subsequentlydiscussed at meetings, both of regional seasconventions and of FAO and non-FAO regionalfishery bodies (RFBs).

RECENT ACTIONSThe latest step in the slow process towardsformal, global acceptance of the need to managefisheries as integral components of dynamicecosystems came with the Conference onResponsible Fisheries in the Marine Ecosystem,which was organized by FAO and theGovernment of Iceland, with support from theGovernment of Norway, in Reykjavik in October2001. At the end of this conference, the ReykjavikDeclaration was adopted, including the pledgethat the signatory nations would "in an effort toreinforce responsible and sustainable fisheries inthe marine ecosystem, ... work on incorporatingecosystem considerations into that managementto that aim."

The intent is therefore now firmly in place, but there is still considerable uncertainty as to exactly what is entailed by EAF, and how toimplement it. To this end, the ReykjavikConference requested FAO to develop draftguidelines to be presented at the Twenty-fifthSession of the Committee on Fisheries (COFI ) in 2003. This work is in progress, and theguidelines have not yet been finalized.Nevertheless, some EAF principles are widelyaccepted and will almost certainly featureprominently in the guidelines. These principlesare already reflected in the Code and aresummarized in the following:

Page 4: PART 2 Selected issues facing fishers and aquaculturistsepub.sub.uni-hamburg.de/epub/volltexte/2010/552/pdf/y7300e02_SOFIA_3.pdfIMPLEMENTING THE ECOSYSTEM APPROACH TO CAPTURE FISHERIES

• The first step in implementing EAF is toidentify and describe the different exploitedecosystems and their boundaries as discreteentities for the purposes of management. Suchclassification will be guided by the availableknowledge of existing fisheries and targetstocks, as well as by other information. Adegree of pragmatism will be required for this,as all ecosystems have open boundariesacross which exchanges occur. However, thedefinitions should aim to identify units thatare largely independent of surrounding areas,and can therefore be effectively managed asindividual entities. This problem, albeit on afar smaller scale, will be familiar to fisheriesmanagers who have already experienced asimilar lack of clarity when trying to identifyreproductively isolated stocks formanagement purposes. The definitions ofecosystems should include lists of species ofimportance, identifying particularlyvulnerable or endangered ones, anddescriptions of the habitats that are critical forthe productivity of the ecosystem.

• Once the ecosystem units have beenidentified, management objectives must bedeveloped for the fisheries of the ecosystem asa whole in order to facilitate obtaining theoptimal benefits in a sustainable manner. Inaccordance with the UN Law of the Sea andthe Code, this should involve – as far aspossible – the maintenance or rebuilding ofthe ecosystem, its habitats and its biodiversityto a status that is capable of supporting allspecies at levels of maximum production.Clearly, within the goal of optimizing benefitsfrom the system as a whole, there will also bethe familiar objectives of conventionalfisheries management, which covereconomic, social and biological desires at arange of species and fisheries scales.However, in EAF, it is also necessary torecognize the ecosystem interactions andconstraints, and to take steps to reconcile thewider objectives so that they are allsimultaneously achievable, rather than inconflict. In striving for this reconciliation, theequitable allocation of resources remains acentral challenge.

• The objectives of EAF must, of course, gobeyond those of the individual fishery or evenfisheries sector. Broader objectives must alsobe considered, including: protection andrestoration of critical habitats and nursery andspawning areas; maintenance of the quality,diversity and availability of resources;restoration or rehabilitation of populationsand stocks, as far as is reasonably possible;and conservation of biodiversity andpopulation structure. Economic and socialobjectives should also be considered at thiswider ecosystem scale by, for example, takingaccount of rural livelihoods and other socio-economic activities that have an impact or aredependent on the ecosystem.

• As already stated, the potential conflicts andinconsistencies in these objectives need to bereconciled in order to arrive at a set ofsimultaneously attainable objectivesencompassing biological, ecological,economic, social and institutional concerns.This is likely to be the most contentious partof EAF implementation and will require fullconsultation with all the legitimate interestedparties in order to ensure their support andcollaboration.

• Once the objectives have been identified andagreed, suitable reference points orsustainability indicators will need to beestablished through which to inform managersand interested parties on how successful theyare being in achieving objectives or remainingwithin constraints. The reference points mustreflect the range of objectives agreed and bebased on the best scientific evidenceavailable. The Scientific Committee forOceanic Research of the IntergovernmentalOceanographic Commission (IOC), with inputfrom FAO, is currently considering suitablereference points for EAF through its WorkingGroup on Quantitative Ecosystem Indicatorsfor Fisheries Management (see:www.ecosystemindicators.org/).

• Clearly, an effective monitoring system will berequired to ensure that the state of theecosystem can be followed through time andcan be compared with the reference points,allowing for corrective action when necessary.

• In fisheries management, managementmeasures are the tools that are used toachieve objectives. Many of the measures thatare available for EAF will be the same as thoseused in conventional single-speciesmanagement: input controls, output controls,technical measures covering gear and vesselcontrols, and area and time restrictions. Thefundamental needs to avoid excess fishingcapacity and to ensure economic conditionsthat promote responsible fisheries are asimportant for EAF as they are for single-species approaches. However, fisheriescontrol measures will have to be developedand extended to apply to the broader scope ofEAF, and controls on non-fishery users need tobecome a part of an ecosystem approach tofisheries management. Consideringecosystems instead of single populations willhighlight the high levels of uncertaintyconcerning the status and dynamics ofecosystems and their elements, and intelligentapplication of the precautionary approach iscentral to EAF.

• The problems associated with open accesssystems and systems in which access rightsexceed the production capacity of theresources are now a well-known cause ofmanagement failure in fisheries. This problemis going to be at least as serious inimplementing EAF, and the allocation ofvarious forms of explicit, legally enforceablefishing and other use rights is integral to EAF.In allocating these rights, it is necessary toconsider all aspects of the ecosystem and theimpacts of all its users, whether they use theecosystem directly or indirectly. Thus, notonly will fishing rights need to be considered,but also development rights, pollution rights,tourism rights and others.

• Implementing EAF entails explicit recognitionof the full range of users that have an impacton the ecosystem, and it is necessary toestablish effective consultation and decision-making processes for regular consultationwith all legitimate stakeholders. EAF’sinvolvement of a broader range of interestgroups is likely to require greater time andcosts for consultation and decision-making,

but is essential for ensuring compliance andcooperation.

FUTURE PERSPECTIVEThrough their support of the Code of Conduct(reinforced by the Kyoto and ReykjavikDeclarations) and of the various FAOInternational Plans of Action, most fishing nationsof the world have committed themselves tostriving to achieve EAF in order to "contribute tolong-term food security and to humandevelopment and to assure the effectiveconservation and sustainable use of theecosystem and its resources" (ReykjavikDeclaration). This could be facilitated byimproved relationships between regional fisheriesand regional environmental organizations. Theinstruments establishing both types of institutiondo not generally provide an explicit mandate forecosystem-based fisheries management, but thereare some exceptions. The International Councilfor the Exploration of the Sea (ICES), theCommission for the Conservation of AntarcticLiving Resources (CCAMLR), the InternationalBaltic Sea Fishery Commission (IBSFC) and otherfisheries institutions have undertaken work that isrelevant, responsive, sound and credible withrespect to marine ecosystems and their relation tohumanity. In addition, the work of environmentalcommissions provides good backgroundinformation that may be taken into account in theecosystem-based management of fisheries.Extending the number of regional fisheriesorganizations with a mandate for adopting anecosystem approach and forging closer linksbetween environmental and fisheriesorganizations will facilitate the effectiveimplementation of EAF in fisheries around the globe.

Implementation of EAF is likely to be a slowand difficult process, requiring considerablesocial and economic adjustments within a globalenvironment that is already facing major socialand economic problems. Most countries arealready struggling to make good progress inimplementation of the Code, and will encounterthe same difficulties, and some additional ones,as they strive to achieve an effective ecosystemapproach in their fisheries management.

Page 6: PART 2 Selected issues facing fishers and aquaculturistsepub.sub.uni-hamburg.de/epub/volltexte/2010/552/pdf/y7300e02_SOFIA_3.pdfIMPLEMENTING THE ECOSYSTEM APPROACH TO CAPTURE FISHERIES

Insufficient financial resources, capacity andexpertise, as well as competition with otherpressing economic, environmental and socialneeds, are all hindering progress inimplementation of the Code. These problemswere anticipated for developing countries underArticle 5 of the Code, which highlights thespecial needs of developing countries, but theyhave not yet been fully addressed.

An ecosystem approach will require themonitoring and assessment of all aspects of theecosystem, a wider range of managementmeasures, possibly more control andsurveillance, and more time dedicated tointeracting with a wider range of stakeholders.National management agencies are typicallyalready fully and frequently overstretched, andEAF will require yet more financial andinstitutional resources and personnel, unless allparties can find means of distributing their skillsand labour more effectively and efficiently. Eitherway, the transition will not be easy and may alsoprove costly. While an ecosystem approach tofisheries management should deliver increasedbenefits in the longer term, as ecosystems recovertheir productivity and structure, there will betransaction costs. Countries will need to makeallowance for these costs, and any global-levelimplementation will require significant assistanceto developing countries so that they can meet thetransaction costs and raise their capacity to therequired minimum level. In all cases, there willalso be a need to look for alternative sources ofincome to help cover the costs of fisheriesmanagement; those who benefit most fromfisheries are one obvious potential source of suchadditional funds.

At present there are widespread public andpolitical concerns about the impacts of fisherieson ecosystems. There can be no doubt that theseconcerns are justified, even if they are sometimesexaggerated. In many countries, fisheries havelimited political and economic weight, and in thisera of globalization there is a risk that fisheriesactivities will be seen as expendable and will becurtailed in cases of doubt, unless there is anadequate response from the fisheries sector to thelegitimate environmental concerns. This risk addsto the urgency of developing management

approaches that provide acceptable results andare adapted to the various characteristics ofcountries and resources. In the recent politicalinitiatives, from the Code to the ReykjavikDeclaration, the global fisheries communityappears to be responding to the environmentalconcerns and to have realized that progress inachieving EAF is essential for the ongoingproductivity of aquatic ecosystems and the well-being of society. The incentives for success,therefore, should be high.

RELIABLE STATISTICS AS AN ESSENTIALBASIS FOR EFFECTIVE FISHERIES

MANAGEMENT

THE ISSUEFisheries management and statisticsAs in all forms of management, the managementof capture fisheries involves synthesizinginformation, analysis and decision-making.1

Without reliable information, no supportabledecisions can be reached, no diagnoses on thestate of fisheries can be performed, and noprognoses on the effects of management controlcan be made. Fisheries management is subject tonatural environmental variability and also tolong-term changes that may be human-induced,particularly pollution and climate change.

There is thus far more uncertainty and risk infisheries management than there is in themanagement of almost any other food sector orindustry. Part of the approach to reducing risk liesin improving understanding through betterinformation, more careful analysis andexperimentation, and improved decision-makingfor long-term results.

The importance of fishery statistics and theeffects of unreliabilityMost methods and approaches to fisheriesmanagement require an assessment of fish stocksin terms of their biomass, size or age composition

and survival, as well as their responses to naturaland fishing mortality. Population models, andtheir dynamics under environmental and human-induced perturbations, are the principal tools.These require data on how much fish has beencaught, the size, age or gender of that fish, andthe growth and survival rates that it exhibits, aswell as additional information on many otherfactors. In order to make stock assessmentsrelevant to site-specific fisheries management,such additional information might include dataon the place and time of capture, thereproductive status and the behaviour of the fish.It is essential to know what is actually beingfished from the wild population, as this affects thestock’s ability to survive and, most important, toreproduce and repopulate. This is why catch andeffort statistics, along with other data regardingthe fish caught, are the key and essential basis foreffective fisheries management.

Statistics are often also used for directadministrative management control to ensure thatfishers are constrained within the set limits.Fisheries management measures often specifyhow much fish may be taken, by whom, by whatmeans, when and where. Thus, total allowablecatch and licence or quota allocation, fishinggear and operational controls, as well as seasonaland area closures, all require monitoring, muchof which can only be achieved by the regular andsystematic collection of reliable statistics on thecatch and the amount of fishing effort.

Fisheries management should protect the foodsecurity and livelihoods of dependentcommunities and try to ensure that benefits fromthe surplus production of wild stocks are broughtinto economies in ways that are appropriate tothe political, social and developmentenvironments in which they occur. Governmentsand industries need reliable statistics in order tounderstand the economic relationships within thefisheries sector and its linkages to other sectors,e.g. finance, energy supply or vessel construction.They must plan for training and investment ifpotential yields are greater than current yields, orfor retraining and stable industry reduction if theexisting capacity is greater than appropriate.Communities need catch and effort statistics ifthey are to achieve and ensure a fair and

appropriate distribution of benefits. Policy-makersneed such statistics so that fishing communitiescan be properly represented when sectoralpolicies are being developed. For example, arecent study2 of inland fisheries in SoutheastAsian countries indicates that catches are severaltimes greater than the official statistics and thatcommunities’ dependence on fish as a source ofprotein, as well as their dependence on thefishing livelihoods of subsistence and small-scalefishers, is far greater than officially recognized,resulting in inadequate recognition of fisheries insocial, economic, nutritional and environmentalpolicy-making.

In summary, unreliable statistics confoundfisheries management on three fronts. They:

• bring greater uncertainty into the stockassessment process, reducing confidence inthe accuracy of fisheries management adviceand often resulting in conflict amongovercautious fisheries managers, overeagerfishers and overanxious environmentaladvocates;

• reduce the public’s confidence in the abilityof fisheries managers to monitor and managethese national or international naturalresources on its behalf, leading to the beliefthat, in the absence of control, fishers areoverexploiting stocks or fishing ininappropriate ways;

• limit economic and social understanding ofthe position and viability of fisheries sectors,causing uncertainty about human resources,social structure, capital and infrastructurerequirements, both in development and forrestructuring.

The reliability of fishery statisticsEver since the modern fisheries era began, theissue of information reliability has pervadedfisheries management, particularly concerninginformation about the quantity and location of

catches. As early as the sixteenth century,Portuguese fishers jealously guarded theirdiscovery of the great cod fishing grounds of theGrand Banks in the Northwest Atlantic. Ascapture fisheries approach maximum yields,scientists require more, and more accurate, dataon which to base their analyses. Most fisheryassessments concerning stocks, fleets andparticipants will always depend on reliable catchand effort statistics, as will economic andfisheries management advice. Given theincreasing demand for food fish and theacceleration of social change, traditionalknowledge, which is often rooted in stablecommunities where it enjoys high levels ofcredence, is insufficient. Societies, technologyand needs change alongside fisheries, andfisheries management must continually adapt tomeet new challenges and circumstances. Reliablestatistics are the most essential information that isneeded.

The range of types of data required to supportfisheries management and policy-making ispotentially enormous. However, financial orhuman resource constraints will forcemanagement authorities to limit collection to themost important data types. In 1998, FAOpublished Guidelines for the routine collection ofcapture fishery data,3 which sets datarequirements within a framework ofpolicy/objectives/indicators/strategy. It also offersadvice on methods of data collection, datamanagement and the planning andimplementation of data collection systems. It isnot prescriptive in that it does not offer a list ofdata types that are always required. Rather, itdescribes a decision-making framework throughwhich the most appropriate data are collected forthe tasks concerned; much of the fisheriesinformation that is collected around the worldmay be reliable but is of little value. In terms of

fisheries management, reliability includesrelevance.

There are several other sources of unreliability.Deliberate misreporting or non-reporting by legaland illegal fishers and other participants(processors, traders) is cited by most managers asa key problem, particularly in developedcountries and international fisheries. However, insome fisheries, particularly small-scale anddeveloping country fisheries, either there is nolaw in place that requires fishery data, or there islittle infrastructure for the collection of such data.Even when data are collected, they may be basedon inadequate sampling or inappropriatesampling design, the origins of which may belack of finance or trained personnel.

Bias can also be introduced by the statisticalauthorities, either inadvertently through theapplication of inappropriate methodologies, orthrough systematic distortions that are introduceddeliberately, for example, to demonstrate that aparticular outcome is in line with internationalobligations (set total allowable catches) ornational policy.

Another problem can be lack of timeliness. Forstatistics to be useful indicators in fisheriesmanagement they need to be prepared regularlyand within time frames that provide fisheriesmanagers with short-term guidance. Delays in thepreparation of statistics can seriously reduce theirutility to fisheries managers. Statistics that are fiveyears old but have only just become availablemay be reliable, but they may have littlerelevance for today.

The appropriate confidentiality of fishery data isalso a factor in understanding the reliability, andhence usefulness, of fishery statistics. A recentreport by the United States National ResearchCouncil (NRC)4 concluded that: "Confidentialityof fisheries data is restrictive to the point ofhindering both research and management." Thereport generally accepted that some fishery datahave proprietary value and that "some level ofconfidentiality is necessary to allow fishermen to

maintain their businesses and to promotereporting of high quality information …information that might not be as accurate if itwere not confidential". The Code of Conduct forResponsible Fisheries makes several references toapplicable confidentiality without defining whatit means,5 partly because its meaning depends onindividual fishery circumstances and partlybecause the legal position regarding businessinformation varies from country to country.Nevertheless, the NRC report recommends thatexisting United States state and federal policieson data confidentiality should be re-evaluated,including creating a mechanism to establishunique proprietary periods for data confidentialityby fishery and "the effects of the loss ofconfidentiality on precision and bias (hencereliability) … in setting the proprietary period foreach type of data".

This means that lowering confidentiality levelsmay well result in less reliable information,particularly in fisheries, where knowledge (eventransient) of the "best" fishing grounds is themajor competitive advantage that fishers have.Confidentiality is therefore not a singledimension. It depends on timing and the needsand authorizations of data users. It also dependson the trust that fishers can expect from datausers, including confidence in data security andan understanding of the uses to which data willbe put.

POSSIBLE SOLUTIONSImproving the reliability of fishery statisticsConsiderable research and analytical effort areregularly put into assessing the precision andaccuracy of fishery data and estimating the extentof the fish catch and fishing effort that is entirelyunreported. Statistical techniques of ever-greatercomplexity attempt to reduce the uncertainty ofthese missing data. The Organisation forEconomic Co-operation and Development(OECD) report of the Workshop on theSignificance of Reliable Statistics to Conduct

Effective Management6 notes that: "Even usingthese techniques it has to be acknowledged thatthe confidence limits attached to the estimatesare wide and contribute significantly to a lack ofconfidence in the resulting advice."

Notwithstanding this general criticism, it islikely that non-reported data will always have tobe estimated in several ways in order to improvethe reliability of fishery statistics. Indeed, well-designed sampling surveys7 can offer goodinsights into a particular data population(including data that have not been sampled).Good statistical design, including validationmechanisms, is thus a primary means ofimproving reliability. Validation mechanismsinclude the periodic conducting of frame surveys,the use of observers and inspectors (as parallelsamplers to the complete enumeration approachgenerally used in logbooks), landings andprocessing throughput data, and vesselmonitoring systems.

It is also often claimed that rights-basedfisheries or community co-managed fisheries, inwhich the control of participants is partly theresponsibility of fishers themselves, may alsogenerate more reliable data, as it is in fishers’ ownbest interests to maintain good records andparticipate in the assessment and managementdecision-making processes. Certainly, incentivesto provide accurate data can be crucial to thereliability of the statistics to which theycontribute.

Whereas it is often essential to ensure theconfidentiality of data in order to ensure theirreliability, the methodologies and processes usedto collect and collate them should be fullytransparent in order to ensure objectivity.Uncertainty associated with statistics shouldalways be expressed, whether as confidencelimits, quality indicators or even annotatedcomments.

In addition, improving reliable statisticsrequires cooperation in the development andadoption of standards. Standardization ofnomenclature and coding, adoption of agreedstatistical methodologies and implementation oftransparent information exchange methodsrequire high levels of transboundary agreementso that the nature and origin of fishery statistics isunderstood across regions, oceans and the world.

In summary, improving the reliability of fisherystatistics involves many factors, including:

• legal and other instruments that obligatefishers to supply reliable data and thatestablish sanctions, penalties and, wherepossible, incentives to support thesemeasures;

• realistic and useful approaches to dataconfidentiality, appropriate access to data and, where possible, incentives to data providers to supply reliable information;

• good statistical design that is cost-effective,sustainable and adaptable to changingcircumstances and that includes validationsystems;

• high-quality and timely informationadministration and processing that is objectiveand transparent and that indicates datauncertainty and quality;

• technological innovations, including vesselmonitoring systems (onboard and satellitecommunications), electronic logbooks andpoint-of-weighing data capture;

• surveillance systems, including inspectors andobservers, to monitor catch and effort,discards and dumping, transhipment andillegal fishing.

Such solutions to the problem of unreliablestatistics – which hamper or, in some cases,confound fisheries management – require twoconditions in order to be implemented: politicalwill and sufficient capacity.

These possible solutions and requirements wereidentified by FAO members in 2002 at aTechnical Consultation on Improving Informationon the Status and Trends of Fisheries, which hadthe specific task of developing a proposal for

improving fishery information in a wide variety ofways and at all levels. The Technical Consultationproposed a draft Strategy for ImprovingInformation on Status and Trends of CaptureFisheries, which will be submitted to COFI in2003.

As well as objectives and guiding principles,the draft strategy contains direct identification ofthe actions required and the roles of states, RFBsand FAO to improve factual understanding offisheries and the exchange of information. Itrecognizes, inter alia, the need for: capacitybuilding in developing countries; data collectionsystems in small-scale fisheries and multispeciesfisheries; development of criteria and methods forensuring information quality and security; anddevelopment of arrangements for the provisionand exchange of information. The draft strategy isintended to provide a framework that motivatesdevelopment partner agencies to fund capacitybuilding in order to improve information andstatistics on fisheries.

GLOBAL PERSPECTIVEInternational responses to the need forreliable fishery statisticsIt is generally recognized that the overall qualityof fisheries production statistics has deteriorated,in relative terms, during the rapid expansion infisheries production of the past 50 years. This hasbeen particularly the case since 1982, when theUnited Nations Conference on the Law of the Sea(UNCLOS) brought about major changes to theregime of the oceans, and developing countriesstarted to experience additional social andeconomic difficulties. These difficulties arosedespite the calls in UNCLOS for "best scientificevidence"; the previous experience of "crashed"fisheries in developed countries, whichdeveloping countries could have learned from astheir fisheries rapidly grew; and the well-foundedand continuing demand for reliable statistics asthe principal basis for fish stock assessment andfisheries management.

Part of the problem is undoubtedly a shortageof money and capacity. However, it is also relatedto the generally low profile of a natural resourcethat is hidden from the eyes of politicians by itsvery medium, and to assumptions that fisheries

can be regarded as common property, open-access systems and that market forces may besufficient to regulate them. In fisheriesmanagement none of these assumptions is true;fisheries have a high profile in terms of globalprotein supply, particularly in developingcountries, and small-scale fisheries in inland andmarine waters are probably more important thanis currently portrayed; open access hasinexorably led to overexploitation in almost allthe fisheries where it is practised; and globaltrade has the potential to skew fisheries awayfrom domestic consumption and self-provisioning, sometimes resulting in theoverexploitation of food fish for export.Fortunately, changes in attitude and political willare entering the mainstream of fisheriesmanagement, particularly since 1992 when theclear linkages between environmentalsustainability and development were globallyaccepted at the United Nations Conference onEnvironment and Development (UNCED).

For many years prior to 1992, fishery scientistsand managers had been calling for betterreliability in fishery statistics. They also acceptedand explained the need for caution in the way inwhich they applied their statistical confidencelimits to analyses and advice, long before theprecautionary approach became the accepteddoctrine of environmental concern. In a directsense, better and more reliable statistics enable astatistical narrowing of confidence limits, hencelowering the degree of caution that needs to beapplied.

The need for reliable fishery statistics is stillbeing voiced in all fisheries fora, from COFI toregional and national meetings. The pace ofinstitutional responses, at least at theinternational and regional levels, is growing. The oldest of the international institutions is theinter-agency Coordinating Working Party onFishery Statistics (CWP), which was originallyestablished in 1959 for Atlantic fisheries but hasmore recently changed its statutes toaccommodate regional bodies from around theworld. CWP has been instrumental inestablishing many standards for fishery statistics,and is currently reviewing its role and approach,particularly in the light of concerns about the

quality of fishery statistics and the need forcapacity building and minimum harmonizedquality standards.

The Code of Conduct for Responsible Fisheriescalls for reliable fishery statistics in Article 7Fisheries Management, as follows:

7.4.4 States should ensure that timely, complete and

reliable statistics8 on catch and fishing effort are

collected and maintained in accordance with

applicable international standards and practices and

in sufficient detail to allow sound statistical

analysis. Such data should be updated regularly and

verified through an appropriate system. States

should compile and disseminate such data in a

manner consistent with any applicable

confidentiality requirements.

In applying the Code to specific objectives,international organizations, in particular the UN,FAO and RFBs, have undertaken a number ofinitiatives that directly and indirectly call for,initiate or provide for improvements in theprovision and dissemination of reliable statistics.The UN Fish Stocks Agreement,9 which came intoforce in 2001, contains detailed statistical needsin Annex I Standard requirements for thecollection and sharing of data, which must beadhered to by all signatories. The FAOCompliance Agreement,10 which is yet to comeinto force, also makes reference in Article 7,Exchange of information, to data needs on fishingvessels and their operational authorizations onthe high seas, thus providing for fleet datathrough the administrative identification ofauthorized fishing effort.

In addition, four international plans of action11

on specific issues have been developed since

1998, each of which contains determinations onthe collection, processing and dissemination ofimproved data that are directly related to theissue. New approaches to ecosystem-basedfisheries management, with high-levelrequirements for data from a wide range ofsources, are also gradually being brought into themainstream of fisheries management (seeImplementing the ecosystem approach to capturefisheries management, p.55).

RFBs are playing an increasingly important rolein fisheries management around the world. Theearlier organizations focused largely on scienceand the development of scientific advice but themore recent organizations – including those stillbeing negotiated12 – are assuming a role infisheries administration and management. MostRFBs have scientific committees, the tasks ofwhich include issues related to fishery statisticsthrough specific standing committees or workinggroups.

Outside the framework of specialized fisheriesagencies, the world recognizes that goodgovernance and development, including ofnatural resources, require improved information.In response to a UN Economic and SocialCouncil resolution on rationalizing andimproving statistics and indicators, thePartnership in Statistics for Development in theTwenty-first Century (PARIS 21) was establishedin 1999, based at OECD in Paris. Throughadvocacy, information exchange andpartnerships, PARIS 21 seeks to contribute tomore effective poverty reduction and improvedtransparency, accountability and effectiveness ofgovernance in developing countries andcountries in transition. Improving the reliability ofcapture fishery statistics (as advocated in the FAO

draft Strategy on Status and Trends in Fisheries) inorder to enable better fisheries management,sustainable fisheries and more effective fisheriesgovernance would undoubtedly contribute tofood security and its role in poverty reduction.

There are some tentative signs that the declineof national authorities’ and development partneragencies’ interest in statistical development,evidenced by the decline of regional and nationalfield projects dealing with fishery statisticaldevelopment, is beginning to abate. There areindications that recognition of the importance ofstatistical development within the mainstream ofnational and regional development planning isreawakening.

CATCH CERTIFICATION AND CATCH DOCUMENTATION

THE ISSUEIncreasing pressure on high seas resources hascaused an intensified search for methods tocontrol the fishing effort, particularly methods toobtain information on unreported catches and tohelp control the fishing effort on heavily fishedspecies. This has led to the introduction of catchcertification and catch documentation schemes.

The Atlantic bluefin tuna is one such heavilyfished species. This fishery is carried out mainlyon the high sea. While the regional fisheriesmanagement organization (RFMO) concerned hasthe authority to regulate the fishing of Atlanticbluefin tunas by its own members, it had noeffective means of dealing with vessels flying theflags of non-members, as in high sea fisheries theflag state has the right to control the fishingactivities of only its own vessels. This is seen as aproblem by countries that are members of theRFBs that manage such fisheries as that for theAtlantic bluefin tuna.

The majority of the vessels of non-members areregistered in countries with open registers. Manyof these countries are small and have little or nosubstantial interest in fisheries. As a result, theydo not exert control over the vessels that areregistered on their open registers. In addition,frequently they do not report landings, or theyreport only very low landings, generally becausethe vessels concerned do not land their catches in

their home countries or ports and are notrequired to report catches to the flag state. Thisexacerbates the problem and leads to uncertaintyabout the quantity being caught in any oneperiod, thereby complicating management for theRFB concerned. In addition, as these vessels areunder no ñ or little ñ control, when fishing thehigh seas they can flout the fisheries managementrules approved by an RFMO, often derivingeconomic advantage from doing so. For thisreason the vessels registered in open registers areoften referred to as "flags of convenience vessels".

This is the context in which it was decided totry to bring pressure on flags of conveniencevessels by limiting their possibilities to markettheir catches.

POSSIBLE SOLUTIONSThe International Commission for theConservation of Atlantic Tunas (ICCAT) was thefirst RFMO to implement a catch documentationscheme regarding the bluefin tuna caught withinits area of jurisdiction. Any bluefin tuna that isimported into any of the ICCAT member countrieshas to be accompanied by a document thatidentifies the country of origin. This measure wasaimed at recording the catches of vessels that areflagged under countries other than ICCATmembers so that the total catches of bluefin tuna

can be recorded for management purposes. Thedocument has the rather misleading name of"statistical document". Within a few years, theresults of this catch documentation scheme hadidentified several countries whose flags ofconvenience vessels were catching up to 30percent of the total bluefin tuna catch. Theintroduction of the scheme was facilitated by thefact that Japan and Europe are virtually the soleimporters of bluefin tuna.

The ICCAT members agreed among themselvesthat multilateral trade sanctions should beconsidered against the open register countrieswhose vessels were making bluefin tuna catchesthat did not comply with the ICCAT managementmeasures. The threat of a possible ban on theirexport of bluefin tuna was enough to encouragethese open register countries to join ICCAT and/orto take measures to ensure that they wereexercising proper control over the vessels flyingtheir respective flags. Any vessel owners who didnot wish to comply with these measures could re-register their vessels in other open registers. Thiscaused significant changes in the registers ofPanama, Honduras and Belize, which had manylongline vessels of Asian origin.

In November 2001, the European Community(EC) banned the import of some tuna and tuna-like species from specific exporting countries,

reflecting the ICCAT managementmeasures, as shown in Table 9.ICCATís success was a useful lesson toother RFMOs that were grappling withthe same problem of illegal,unreported and unregulated (IUU)fishing and non-contracting parties.The problems of CCAMLR were verydifferent from those of ICCAT in thatCCAMLR was concerned about theoverfishing of toothfish in the southernlatitudes. In the early 1990s, the catchof toothfish by longline in the verydeep waters of southern latitudes hadexpanded rapidly as a result of its highprofitability, and had attracted theattention of many entrepreneurs. TheCCAMLR area is very difficult tomonitor because of its immense size,the relative lack of coverage by

monitoring, control and surveillance (MCS)activity, and the limited presence of exclusiveeconomic zones (EEZs) around the circumpolarregion. The French and Australian navies werearresting vessels that had been caught fishingwithout authorization in the 200-nautical mileEEZs around their respective territories (theKerguelen and Crozet Islands for France, and theHeard and McDonald Islands for Australia), butsignificant catches were being made in high seasareas over which no country had jurisdiction;according to some estimates these unreportedcatches were larger than those reported in theofficial statistics. In response, CCAMLRintroduced a catch documentation scheme. Thescheme requires that all the toothfish landed inthe ports of its participating parties beaccompanied by a catch document, which isauthorized by the vessel’s flag state andsubsequently verified at the port of landing by anauthorized flag or port state official. Additionalgovernment authorization is required before thetoothfish can enter international trade, and thecatch document must accompany the toothfishthrough all stages of the export cycle. Sincecoming into effect, the scheme has resulted in 18reports of vessels attempting to land unauthorizedcatches of toothfish.

Parties to the 1998 Agreement on theInternational Dolphin Conservation Program(AIDCP) adopted a scheme in June 2001 underwhich they could issue certificates indicating thatcanned tuna is "dolphin-safe" (i.e. was harvestedwithout dolphin mortality or serious injury). Thedolphin-safe tuna certificate scheme is differentfrom the others in that it is not directed at trade or

management measures but at market objectives.Observers are present on all large purse seinevessels. At the time of catch, dolphin-safe tuna isstored separately from tuna that is not dolphin-safe. The tuna tracking number attached to eachfish follows it through the system, and copies ofthe dolphin-safe certificate and the original tunatracking form are kept by the Secretariat of theInter-American Tropical Tuna Commission(IATTC). Because it is concerned withenvironmental issues rather than with fisheriesmanagement or trade, this information is notconsidered to be a trade document (as the tunaand toothfish catch documents are), even thoughthe methodologies of control are similar.

The success of the trade document in providingbetter catch data and in curbing IUU fishingactivities has led ICCAT and other RFMOs toimplement similar measures for other species.ICCAT has extended the catch documentationscheme to include swordfish and bigeye tuna.The Indian Ocean Tuna Commission (IOTC)covers bigeye tuna and swordfish with itsscheme. This scheme requires certification byofficials representing the flag state, and care willhave to be taken to ensure that the verificationprocess is carried out in a satisfactory manner.The Commission for the Conservation of SouthernBluefin Tuna (CCSBT) is planning to introduce acatch documentation scheme for Southernbluefin tuna.

RECENT ACTIONSThe proliferation of catch documentationschemes has led the International Coalition ofFisheries Associations (ICFA) to request that allsuch documentation schemes should bestandardized. The Chair of the Meeting ofRegional Fisheries Bodies,13 with FAO assistance,held a meeting in La Jolla, the United States, atwhich to consider the matter. This meetingproduced recommendations on the contents of astandard catch certificate and catch documentand on the procedures for processing such adocument. FAO is currently designing the

standard documents with input from customsofficials who have had experience in handlingsuch documentation. The results will bepresented at the Third Meeting of RegionalFisheries Bodies, which is scheduled to takeplace in March 2003 at FAO, straight after theCOFI meeting.

The significance of the terms "catch" and"landings" of fish is often unclear to users andreaders. This leads to confusion. CWP hasadopted a standard terminology in order toeliminate such confusion and has recommendedthat FAO and RFMOs using catch documentationschemes should adopt this standard terminology.There have also been problems withimplementation, such as choice of the mostappropriate conversion factors for estimating liveweight equivalent from product weight. Anotherproblem arises from double counting whendifferent parts of the same fish are exported todifferent countries, each part being accompaniedby its own separate set of documents.

The growing practice of fattening bluefin tunain net cages at tuna farms is making it difficult forthe managers of bluefin fisheries to enforce quotaallocations. Such farming activity is spreading,particularly in the Mediterranean Basin, wherebluefins are caught at sea by purse seines or intraps and subsequently transferred into floatingnet cages to be fed for a period ranging from afew months to two years.

Recording the volumes of fish caught at sea is adifficult operation, as the fish are generallytransferred directly from the purse seines to thenet cages without being taken out of the water. Atpresent, such catches are statistically recordedonly after the fish have been landed or harvested.The information available, therefore, does notinform managers about which vessels (and whichfishing nation) caught the fish, where it wascaught and at what size it was caught. Thismeans that the system of allocating bluefin catchquotas to fishing nations becomes increasinglydifficult to monitor and enforce.

The Convention establishing the Commissionfor the Conservation and Management of HighlyMigratory Species in the Central and WesternPacific Ocean has not yet entered into force. TheCommission does not yet exist as a functioning

body, and is not expected to do so for severalyears. However, the Standing Committee on Tunaand Billfish (an ad hoc meeting of scientists whoprovide analysis of the fisheries in the region) isconsidering the introduction of catch certificationand trade documentation because there isconsiderable potential for unreported catches inthe Central and Western Pacific area. This isexpected to be very difficult to enforce owing tothe wide range of fishing fleets involved and thediversity of the ports at which the vessels couldland.

IATTC is currently considering a resolution toestablish a catch documentation scheme forbigeye tuna taken by longline vessels.

FUTURE PERSPECTIVE Catch documentation schemes had spectacularsuccess in their early implementation, when theywere concerned with one species of large fishfrom one region that was a target for IUU fishingvessels. Extending the system to smaller fish, insome cases from several vessels or regions, isgoing to be more problematic and may lead toconfusion among species, especially whencustoms officials have no previous experience ofsimilar initiatives. The problem of customs codesis difficult; however it is thought that the use ofcatch documentation schemes will, in general,assist in providing better statistics on catches andinternational trade in fish, as well as identifyingIUU fishing vessels and bringing action againstthem.

While, in principle, the catch certificate andtrade document schemes described could behelpful for any fishery managed by an RFMO, it isrecommended that priority for the developmentof new schemes should be given to fisheries thatare, or may be, subject to significant levels ofIUU fishing. Priority attention should also begiven to fisheries harvesting species that arecovered by catch certificate or trade documentschemes in other fisheries, so as to support theexisting schemes of other RFMOs. Considerationshould also be given to assisting developingcountries in meeting the requirements of catchcertification or trade documentation schemes, asmany of these countries rely on fisheries productsfor substantial amounts of foreign exchange.

POVERTY ALLEVIATION IN SMALL-SCALEFISHING COMMUNITIES

THE ISSUEWhile economic growth has helped to reduce theproportion of the world’s population that is poor,the number of people who remain poor isunacceptably high. The positive impacts ofgrowth on poverty have been less than expected,in part because of inequitable distribution of thebenefits, population increases and the effects ofthe HIV/AIDS epidemic. As a result, manygovernments and donor agencies have refocusedtheir attention on poverty. The World Bank’sWorld Development Reports for 1990 and 2000,the UN World Food Summit for SocialDevelopment in 1995, and the UN MillenniumDeclaration adopted in 200014 all consideredpoverty alleviation as a principal priority.

In the past, while many developmentinterventions were implicitly aimed at reducingpoverty, most did not explicitly focus onimproving the living conditions of poor peoplebut aimed at accelerating economic growththrough technology and infrastructuredevelopment and through market-led economicpolicies. The lack of an explicit focus on povertymay, in part, explain why the impacts on povertyof many interventions have been neutral, andsome may actually have been detrimental.Certainly, the continued levels of poverty insmall-scale fishing communities,15 and in theworld as a whole, require that all thoseconcerned take a fresh look at the problem.

It is increasingly acknowledged that poverty isa very complex, multidimensional concept thathas many determinants and is concerned with farmore than low earnings, i.e. income poverty.16 Anexplicit emphasis on poverty is necessary for abetter definition and understanding of what it is,so as to be able both to measure progress towards

poverty alleviation targets and to gain improvedawareness of whom poverty affects and what arethe most effective strategies for tackling it.

Poverty in small-scale fishing communities, asin other sectors, is difficult to measure. Whilethere are many studies of poverty in farmingcommunities and among the urban poor, fewempirical studies17 have focused on fisheries.Those that have often concentrate exclusively onincome and on the fishers themselves, rather thanon a broader concept of poverty in fishinghouseholds and communities.

There is now an acceptance that poor fishersand their dependents are not a homogeneous,unchanging group of people. The levels ofabsolute and relative poverty, within and amongsmall-scale fishing communities, varyconsiderably by area, country and region.

Although there are poverty traps in fishingcommunities, over time community members cansometimes become less, rather than more, poor.Fishing communities are often relatively cash-richcompared with farming communities, mainlybecause fishers sell a larger proportion of theirproduction, more frequently and consistentlythan do most farmers. They remain vulnerable tosudden variations in earnings, however, makingfishing communities often more vulnerable thanare communities that rely exclusively on farming.In fact, the issue of vulnerability may be asimportant as poverty is. It should be recognized,however, that some factors may be importantdeterminants of poverty but not of vulnerability,and vice versa.

Small-scale fishing communities are vulnerableto many events, the outcome of which may bepoverty. Examples include: climatic/natural

events such as yearly and seasonal fluctuations instock abundance, poor catches, bad weather andsuch natural disasters as cyclones and hurricanes;economic factors such as market pricefluctuations and variable access to markets; andthe dangers of working at sea. People in small-scale fishing communities may also be vulnerableto poor health and other wider determinants ofpoverty. There is an important need to improvethe understanding of what makes fishersvulnerable to events and factors that result inpoverty, what makes it difficult to improvelivelihoods, and what potential solutions exist.Unfortunately, studies suggest that vulnerabilityappears to be increasing among the poor insmall-scale fishing communities.

In developing countries, many millions ofpeople live in small-scale fishing communities.While it is now acknowledged that not all small-scale fishers can be assumed to be poor, a largeproportion of them are, and remain so, despitethe efforts of donor agencies, national and localgovernments, non-governmental organizations(NGOs) and the communities themselves.Reasons for continuing poverty include factorsfrom within and outside the fisheries sector:vulnerability, as already discussed; insecureaccess to resources; tendency to resourcedepletion; the remoteness of many fishingcommunities; the agro-ecological characteristicsof nearby land; low socio-economic, cultural andpolitical status; a lack of political and financialsupport (often as a result of an emphasis on semi-industrial and industrial fishing); and competitionand conflict with industrial vessels and othereconomic sectors in coastal areas.

Despite the difficulties of measuring poverty insmall-scale fishing communities and of definingwho is a fisher (as fishers farm, and farmers fish)and what is a fishing community, some crudeestimates of the numbers of income-poor fisherscan be proposed as shown in Box 9, whichsuggests that 5.8 million, or 20 percent of theworld’s 29 million fishers, may be small-scalefishers earning less than US$1 a day.18 The

income-poor in related upstream anddownstream activities, such as boatbuilding,marketing and processing, may be as many as17.3 million people. These figures suggest anoverall estimate of 23 million income-poorpeople, plus their household dependents, relyingon small-scale fisheries.

POSSIBLE SOLUTIONSPoverty eradication strategies must be wellfocused, but need to acknowledge that economicfactors are not the only determinants of poverty,which also include social, cultural and politicalvariables. Understanding these determinants iscrucial to the design and implementation ofeffective solutions.

It can often be difficult to help poor people tocome out of poverty because of their poor health,illiteracy, lack of time and aversion to risk. Poorpeople’s lack of influence and power is anespecially important problem, and necessitatestrying to identify win-win solutions that are in theinterests, not only of the poor, but also of the rich,the élite and the powerful.

The World Bank suggests that "withouteconomic growth there can be no long-termpoverty reduction", citing the experience of thelast decade. Between 1990 and 1999 thoseregions of the world with the fastest economicgrowth made the most gains in terms of reducingthe numbers of people living on less than US$1 aday. In regions that experienced economiccontraction, the numbers of income-poorincreased. However, without concerted efforts toredistribute the wealth from economic growth,the gap between rich and poor is likely to widen.

Solutions outside the fisheries sector can be asimportant, if not more so, than strategiesemployed within the sector, so action andcoordination across sectors may be required.

Strong economic performance in a country,especially of labour-intensive sectors, is importantfor small-scale fishing communities because itcan create alternative employment opportunities –which are vital given the current levels ofresource exploitation and the large numbers ofpeople involved in fishing. Diversity and mobilityare key livelihood strategies for the poor.

Increases in general economic performance anddiversification not only offer the potential forsome fishers to leave fishing, thus benefitingthose who remain, but also create a wider rangeof opportunities and possible strategies forcontributing to the household livelihoods of thosewho remain. This appears to have occurred inMalaysia, for example, which is one of the fewdeveloping countries in which the number offishers showed a decreasing trend in the 1990s.Increases in general economic performance alsoprovide opportunities to improve health services,education, public service delivery (such as theprovision of roads and, thus, access to markets),governance, political stability and safety nets, allof which are likely to help with povertyalleviation in small-scale fishing communities.Even where there is little economic growth, thereis still scope for progress towards povertyalleviation if policy-makers address these issues.A notable and often cited example is the IndianState of Kerala, which has achieved very highlevels of social attainment (education, health,longevity) and a low incidence of poverty, eventhough economic growth has been limited andper capita income remains low.

Solutions within the fisheries sector: As there islittle scope for the further expansion of capturefisheries, given the current levels of exploitation,it is crucial to manage fish resources so as toavoid further resource depletion. Effective andflexible management can improve incomes bylimiting entry to the coastal fisheries, avoidingwasteful investments and overcapitalization, andsupporting sustainable exploitation practices. Itcan also improve incomes for the poor byeffectively protecting small-scale fishers from theactivities of large-scale industrial vessels, therebyenlarging the resource base that the poor canexploit.

There are many different types of fisheriesmanagement regime, including unregulatedcommon property (i.e. de facto open access),regulated common property (in which regulationranges from weak to strong) and regimes thatseek to use private property rights as amanagement tool. A particular managementregime and its related regulations can have a

significant influence on poverty, as can thegovernance framework and institutionalarrangements that determine the distribution ofwealth. Management regimes must therefore beappropriate for each specific context and mustbe enforced effectively so as to contribute topoverty alleviation in small-scale fishingcommunities.

Community management and, perhaps evenmore so, co-management (the sharing of powerand responsibility between government and theresource user, e.g. small-scale fishers) offerpromising solutions to poverty alleviation,although collective action and co-managementcan require many years of capacity buildingbefore they are effective. Box 10 provides anexample of successful co-management in Côte d’Ivoire.

The importance of alternative employmentopportunities has already been stressed.Aquaculture is often suggested as an obviousalternative to capture fisheries but, although itdoes have potential, there may be constraints thatprevent poor capture fishers from moving intoaquaculture. Such constraints may include highcapital costs, a lack of suitable sites and a lack ofaccess to land and water for the poor. Marine-based (eco-)tourism provides another possiblealternative that is generating interest in manycountries.

Development assistance has often been foundto be particularly effective when it supportswomen in post-harvest and value-addedactivities, because they often show greater desireand ability to save and contribute to theenhancement of household assets than men do.Given that managerial ability and skill are keydeterminants of the success of individual fishingoperations, interventions that upgrademanagement and skills and address dynamicentrepreneurship may be especially likely to havean impact on poverty in fishing communities.

The following solutions to poverty alleviationwithin the fisheries sector are also worthmentioning:

• Reducing/removing subsidies on productioninputs may lead to the use of smaller boatsand engines, reduced expenditure on fuel and

71

Page 19: PART 2 Selected issues facing fishers and aquaculturistsepub.sub.uni-hamburg.de/epub/volltexte/2010/552/pdf/y7300e02_SOFIA_3.pdfIMPLEMENTING THE ECOSYSTEM APPROACH TO CAPTURE FISHERIES

increased expenditure on labour. In the longterm, this should increase profits, create moreemployment and income for poor fishers andreduce debt. The removal of subsidies tolarge-scale fishing operations and relatedinfrastructure would also remove marketdistortions that often disadvantage small-scalefishers. However, short-term socialconsiderations are often more important thanlong-term ones, so subsidies remain.

• Support must be provided for both ex-anterisk management and the ex-post copingmechanisms that are used to deal with shocksand stresses, while noting that strategies toreduce vulnerability may need to be differentfrom those aimed at reducing poverty.

• Support for effective organizations in fishingcommunities (e.g. cooperatives, politicallobbying groups and social support groups)can be of benefit to the poor in terms ofincreasing access to credit, effecting policychange in favour of the poor and reducingvulnerability. Such organizations are mostbeneficial when: governments are supportiveand enabling, rather than constraining orrestrictive; fishers identify strongly with theaims and motivations of the organizationsconcerned; and there is able leadership withinfishing communities.

RECENT ACTIONSConsiderable work is now being undertaken toimprove the understanding of whom and wherethe poor are, why they are poor and whatmechanisms are most effective for povertyreduction. This explains the increasingimportance of poverty mapping, the developmentof poverty assessment methodologies and theemphasis on well-being and capabilities (ratherthan on income alone), which focus onsustainable livelihoods. However, few suchanalyses have been carried out in fishingcommunities.

Recent activities outside the fisheries sector.Several of the poorest developing nations havedeveloped, or are in the process of developing,Poverty Reduction Strategy Papers (PRSPs) jointlywith the World Bank and the International

Monetary Fund (IMF). Although few of thesecurrently focus specifically on fisheries, they arelikely to be of help where fisheries are identifiedas a key economic sector or, more generally,where strategies to reduce poverty are in placeand small-scale fishers are poor.

Recent debt relief to heavily-indebted poorcountries (HIPC), accompanied by efforts toimprove health, education and other socialservices, should also be of benefit to small-scalefishing communities.

Bilateral assistance is focusing increasingly onpoverty reduction and food security. Most donorshave now put in place strategies and criteria thatseek to ensure that their assistance is reaching thepoor.

Recent activities within the fisheries sectorinclude those carried out by civil society, donoragencies and national governments.

NGOs and civil society continue to work withlocal fishing communities to reduce povertythrough credit, retraining and alternativeemployment creation programmes and throughsupport for fishing-related and socialorganizations.

The plight of fishers and their vulnerability toAIDS were reviewed at a recent meetingorganized by the Asian Fisheries Society and theInternational Centre for Living Aquatic ResourcesManagement (ICLARM).19

National governments are becomingincreasingly involved in both co-managing thecontrol of industrial vessels’ activities in waterswhere small-scale fishers operate and ensuringfairer international access agreements. There isalso a growing realization that many small-scalefisheries need to be restructured. The Philippinesoffers an example of some degree of success inthe government’s implementation of agovernance model that is based on communitymanagement systems.

SFLP also supportspolicy-oriented normative activities such as thedevelopment of guidance materials for povertyreduction policies in fisheries.

OUTLOOKThe international community now shares a visionthat makes poverty reduction a priority objective.It is becoming clear, however, that this objectiveis more difficult to achieve than was previouslythought and that it requires special strategies andtargeting.

BOX 9Global estimates of income-poor small-scale fishers

and related employment in marine and inland capture fisheries

Assumptions:

1. Overall figures for the numbers of fishers are based on

1990 FAO data.

2. Marine deep sea fishers and those engaged in aquaculture

are excluded, along with all those in North America and

Europe.

3. The percentage of total fishers and those engaged in

related employment who are estimated to be income-

poor is based on the World Development Report 2000/1figures for the share of the population in each region in

1998 that was living on less than US$1 a day, i.e. it is

assumed that the level of poverty in fisheries is the same

as it is in other sectors.

4. There are assumed to be three people in related jobs for

every one fisher.

5. One hundred percent of all inland fishers are assumed to

be small-scale, while 90 percent of all marine coastal,

unidentified marine and unspecified fishers are assumed

to be small-scale.

Given the importance of overall economicperformance, the expected expansion of theworld economy can be viewed positively, as canan improving balance of external debt in HIPC.However, questions remain about whether thisoverall growth will be sustained, whether it willbe reflected in developing countries, whethersmall-scale fishing communities will benefit, andwhether the gap between the rich and the poorcan be narrowed.

It is promising that the weaknesses of manyconventional centralized fisheries managementregimes are being increasingly recognized andtackled, when public resources permit. There is agrowing awareness of the need for a processapproach to fisheries management (accompaniedby capacity building and reform) that isparticipatory and flexible enough to adapt tochanging conditions. Co-management andcommunity management arrangements offersome potential in this regard.

Greater awareness that good governance (byadministrators, politicians, local élite groups,fishers and scientists) lies at the heart of many ofthe solutions to poverty in small-scale fishingcommunities is vital. However, despite this

realization, improving governance and theinstitutional capacity to effect meaningful changein the poverty status of small-scale fishingcommunities is still a formidable challenge, eventhough at least it is a challenge that is now beingembraced.

Without outside assistance, poverty status in thesmall-scale fisheries sector can improve onlyslowly. Improved governance paradigms andcapable management institutions are needed, andthey will not become effective unless publicresources are provided – at least in an initialstage. Although there is a growing realization ofthis need in concerned milieus, it is still not clearwhat action such realization will lead to.

ANTIBIOTIC RESIDUES IN AQUACULTUREPRODUCTS

THE ISSUE Background. As in other animal productionsectors, antibiotics are used in aquaculture duringboth production and processing, mainly toprevent (prophylactic use) and treat (therapeuticuse) bacterial diseases.20 Antibiotics have alsobeen recommended and used as disinfectants in

BOX 10Fisheries co-management in Aby Lagoon, Côte d’Ivoire

Fisheries co-management in Aby Lagoon arose out of a crisis

caused by stock depletion, misguided external support, the

inability of the fisheries administration to implement

satisfactory management measures and the desire of both

government and resource users to reduce conflicts between

the state and resources users. Co-management has

contributed to improving livelihoods and poverty alleviation

through increased production and greater value of products

and through investments in non-fisheries activities. There is a

new sense of empowerment and self-respect in the

community, and greater security from better access to

resources and supportive social networks.

fish handling, but this practice has proved to beineffective and is generally not approved by thefish inspection services. Antibiotics have notalways been used in a responsible manner inaquaculture and, in a number of reportedsituations, control of the use of antibiotics has notprovided a proper assurance of the prevention ofrisks to humans. FAO, the World HealthOrganization (WHO), the International Office ofEpizootics (OIE) and a number of nationalgovernments have already raised the issue ofirresponsible use of antibiotics in all productionsectors, with particular concern for the potentialrisks to public health. Many governments aroundthe world have introduced, changed or tightenednational regulations on the use of antibiotics, ingeneral and within the aquaculture sector.

Public health concerns. When consumed directlyby humans as medicine, antibiotics may causeadverse side-effects, but these can generally beavoided through adhering to the recommendeddose and duration of therapy. However, whenantibiotics are unintentionally ingested asresidues in food, the amount ingested cannot bequantified or monitored and may cause directhealth concerns, such as aplastic anaemia, whichis said to be associated with chloramphenicol.These direct effects pose significant risks tohuman health. In addition, the unintentionalconsumption of antibiotics is leading to thedevelopment of antibiotic resistance in bacteriathat are pathogenic to humans, and this isanother important problem that has not yetreceived adequate attention. The development ofantibiotic resistance by pathogenic bacteria isconsidered to be one of the most serious risks tohuman health at the global level.21 The problemarises when bacteria acquire resistance to one ormore of the antibiotics to which they wereformerly susceptible, and when that resistance

eventually makes the antibiotics ineffective intreating specific microbial diseases in humans.22

Recognition of the risks associated with the directand indirect effects on human health of bothactive and passive consumption of antibiotics hasled to bans on the use of certain antibiotics inanimal food production (particularly thoseantibiotics for which no safe residue levels can bedetermined) and to the establishment ofmaximum residue limits (MRLs) for those withknown risks.

Effects on the industry. During the last year, thedetection of chloramphenicol in internationallytraded shrimp products has caused muchconcern. The substance has been found incultured products, resulting in a slowdown inimports, causing economic loss among theconcerned producers and reflecting negatively onall shrimps and on aquaculture overall.

POSSIBLE SOLUTIONSThere are two strategies for achieving acceptablelevels of antibiotic residues in aquatic products:limiting the use of antibiotics in aquacultureenterprises; and establishing and enforcing MRLsin aquaculture products. Both strategies must beused.

Limiting the use of antibiotics. Antibiotics arenecessary for specific and identified uses inaquaculture. Regulation of their commercialavailability is one of the ways to ensure that theyare used responsibly in aquaculture.

There are several possible strategies for limiting

the commercial availability of antibiotics. Thetwo most basic are: identifying the permittedantibiotics (and their MRLs) and prohibiting allothers, or identifying the prohibited antibioticsand permitting all others. The first strategy isclearly more in line with the precautionaryapproach.

A possible scheme for limiting the use ofantibiotics by using the first basic strategy isoutlined in Table 10.

Establishing and enforcing MRLs. In the twelfthedition of the Procedural Manual of the CodexAlimentarius Commission (CAC),23 the maximumlimit for residues of veterinary drugs (MRLVD) isdefined as "the maximum concentration ofresidue resulting from the use of a veterinary drug(expressed in mg/kg on a fresh weight basis) thatis recommended by the Codex AlimentariusCommission to be legally permitted orrecognized as acceptable in or on a food."

The MRLVD is based on the type and amount

of residue considered to be free from anytoxicological hazard for human health, asexpressed by the acceptable daily intake (ADI) orby a temporary ADI that utilizes an additionalsafety factor. The MRLVD also takes into accountother relevant public health risks, as well as foodtechnological aspects. When establishing anMRL, consideration is also given to residues ofthe same drug that occur in food of plant originand/or in the environment. Furthermore, the MRLmay be reduced so as to be consistent with goodpractice in the use of veterinary drugs, and to theextent that practical analytical methods areavailable.24

RECENT ACTIONSLimiting the use of antibiotics in aquaculture.Some countries or regions, such as the EC,Canada and Norway, approve a limited numberof antibiotics specifically for use in aquaculture.In Canada, the antibiotics approved foraquaculture use are: oxytetracycline, sulfadiazine(trimethoprim), sulfadimethoxine (ormetoprim)and florfenicol.25 Not only do the regulationsapprove the types of antibiotic that can be used,they also usually specify the species, diagnosis,dose, duration and withdrawal period to be

23 CAC is a joint commission formed by FAO and WHO. Since

the first steps were taken in 1961 to establish a Codex Alimen-

tarius (food code), CAC, as the body charged with developing

that code, has drawn world attention to the field of food quality

and safety. CAC is charged with developing food safety stan-

dards for worldwide application, and Codex standards have be-

come the benchmarks against which national food measures

and regulations are evaluated within the legal parameters of the

World Trade Organization’s Sanitary and Phytosanitary Agree-

ment (WTO/SPS).

observed when an antibiotic is used as atherapeutic agent. Compliance with theseconditions and regulations assures that theresidues in products are kept below the MRLs andthat the risk of pathogenic bacteria developingresistance is negligible or, at least, acceptable.

Chloramphenicol is still an authorizedantibiotic in human medicine. Patients who use itas a medicine are taking a risk, but it is a risk thatthey can (and should) assess and understand fully.In addition, a course of treatment withchloramphenicol should only be followed underthe direct supervision of a qualified physician.Chloramphenicol ingestion through theconsumption of fish products containing residues,however, could pose health hazards to humans,which could have serious implications. This iswhy chloramphenicol is authorized for use inhuman medicine, but not for veterinaryapplications.

Until 1994, the EC’s MRL for chloramphenicolwas 10 ppb as a provisional (Annex III) allocation.After 1994, when it became clear that data todemonstrate a safe level of chloramphenicolcould not be established, the MRL was changedto zero (Annex IV). The detection limits forchloramphenicol by the accepted testingmethodology using high-performance liquidchromatography (HPLC) was then 5 to 10 ppb.Thus, effectively, the MRL for chloramphenicolbecame 5 ppb. Over the past two years, severaltests for chloramphenicol based on enzyme linkedimmunosorbent assay (ELISA) technology havecome on to the market. The stated manufacturer’sdetection threshold for chloramphenicol usingthese ELISA-based tests is 0.05 ppb. Since the ECdoes not recognize an MRL for chloramphenicol(zero tolerance), by using more sensitive tests,analytic chemists have disqualified many of thefood items that previously had been accepted assafe for human consumption.

There are nine substances included in Annex IVof Regulation 2377/90/EEC that may not be usedin food producing species because no safe levelof residue can be determined: chloramphenicol,26

chloroform, chlorpromazine, colchicine,

Dapsone, Dimetridazole, Metronidazole,nitrofurans (including Furazolidone) andRonidazole. The presence of an Annex IVsubstance residue (including metabolites) is primafacie evidence of the use of a prohibitedsubstance in a food animal species.

In the United States, several drugs areprohibited for extra-label animal and human druguses in food producing animals. Those relevant toaquaculture interests include: chloramphenicol,Dimetridazole, Furazolidone (except forapproved topical use), Nitrofurazone (except forapproved topical use) and fluoroquinolones.

Approved antibiotics can be bought andutilized under two conditions: over the counter,or on prescription by a qualified professional. InCanada, the over-the-counter purchase ofoxytetracycline is supported by the existence of aMedicating Ingredient Brochure, whichrecommends the conditions for its use. It isimportant that information on the responsible andcorrect use of antibiotics be provided toaquaculturists. In developed countries (e.g. theUnited States, EC countries, Canada), mostapproved antibiotics can only be purchased andutilized on prescription, and under the guidanceof a qualified professional.27

For extra-label use, a qualified professionalmay write a prescription for the use of anapproved antibiotic under conditions that varyfrom those approved. In this case, the approvingofficer will provide specific instructions for theantibiotic’s use and is responsible for itsapplication. Under the Canadian regulations, thequalified professional assumes full responsibilityfor any drug residue violation. Under the UnitedStates regulations, there is provision forauthorizing licensed veterinarians to prescribeextra-label uses of antibiotics in animalproduction for drugs that have been approved for

77

26 See: www.emea.eu.int/pdfs/vet/mrls/chloramphenicol.pdf

27 Laws define which qualified professionals are authorized to

write drug prescriptions for the treatment of fish in aquaculture

and are responsible for controlling them. Such professionals may

have different professional backgrounds in different countries;

for instance, in the EC and the United States, they are veterina-

rians (with proper aquaculture training), but in some countries

they could be biologists (aquaculture) with proper training in

fish medicine and human public health.

human use only. However, the same regulationprovides that the United Stated Food and DrugAdministration (USFDA) "may prohibit an extra-label drug use in animals if, after affording anopportunity for public comment, the agency findsthat such use presents a risk to the public health".This regulation establishes, de facto, a largedifference from those countries that allow onlythe use of approved antibiotics for aquaculture.

This could create situations of lack of control.As expressed by USFDA, "the data andinformation necessary to determine, in particularsituations, whether the resistance level at time ofslaughter would be increased above normal as aresult of extra-label use is not generally availableto practising veterinarians, who must make theextra-label use decisions". In addition toantibiotic residues, therefore, the increasedresistance to the specific antibiotic should, inprinciple, also be monitored. In countries that donot have an effective veterinary servicecompetent in aquaculture or that lackmicrobiological monitoring, the extra-label use ofantibiotics implies irresponsibility and a seriousshortcoming in the management of risks tohuman health.

There are also provisions regarding the use ofantibiotics to deal with emergencies (e.g.epidemics) and research. In general, bannedantibiotics and banned veterinary drugs posesignificant demonstrable risks to human health.

Box 11 provides a list of the antibiotics andveterinary drugs that are currently banned in theUnited States. Banned antibiotics and veterinarydrugs may vary from country to country.

Establishing and enforcing MRLs. The proceduresby which CAC sets MRLVDs are complex and,owing to the inevitable internationalinvolvement, slow. Data are analysed by the JointFAO/WHO Expert Committee on Food Additives(JECFA), which meets only once a year. When arecommendation is reached (after much JECFAconsideration), the conclusions are passed toCAC’s own expert committee, the CodexCommittee on Residues of Veterinary Drugs inFood (CCRVDF), for further evaluation.28

Establishing MRLs for fish presents severalproblems, including the identification of what areedible tissues and the complex pharmacokineticproperties and metabolism of veterinary drugs infish. The only full CAC MRLs for aquaculturespecies listed in the database are for theadministration of oxytetracycline at 100 µg/kg to"fish" and "giant prawn", but several additionalMRL proposals from JECFA are now within theCAC system. From this it is clear that it will bemany years before CAC sets a usable list of MRLs

relevant to aquaculture; national or market-areaMRLs will therefore predominate in theprotection of consumers within their areas. Theproducts that are being assessed by JECFA aregiven in Table 11.

As well as the MRLs set by JECFA, severalcountries or country groups have set their own.The MRLs relevant to aquaculture in the ECEuropean Economic Area (EC EEA) and theUnited States are given in Tables 12 and 13. Theinformation on MRLs for veterinary drug residuesin Canada can be found on the Health CanadaWeb site: www.hc-sc.gc.ca/english/index.html.Specific MRL information is given at:www.inspection.gc.ca/english/anima/fispoi/manman/samnem/bull8e.shtml.

The Bureau of Veterinary Drugs, Health Canadahas approved six drug products (eight drugsubstances) for use in aquaculture (Table 14).Additional information on amended MRLs is alsoavailable at: www.hc-sc.gc.ca/english/media/releases/2002/2002_08bk1.htm (see Table 15).

The British Columbia Ministry of Agriculturealso has a valuable Web site with information onaquaculture and, in particular, the use ofantibiotics in aquaculture: www.agf.gov.bc.ca/fisheries/health/antibiotics.htm.

Japanese MRL information can be found at:www.ffcr.or.jp/zaidan/ffcrhome.nsf/pages/e-info-foodchem. Only two aquaculture MRLs areposted for fish and shellfish in Japan: 0.2 ppm for

oxytetracycline and 0.2 ppm for Spiramycin.Listings published elsewhere suggest that a widerange of veterinary medicines has been approvedfor use in fish in Japan.

MRLs of approved antibiotics are usuallyconservative. Processing, cooking and frozenstorage can reduce the residual levels ofantibiotics.29 However, data regarding the effectof processing, cooking and freezing aquaticanimal products on the degradation of antibioticresidues in aquatic animal products are scarce; itis therefore essential to conduct proper exposureassessments, in the form of risk assessments, notonly in order to understand the risks but also toreassure consumers.

In the EC, consumer safety is addressed viaMRLs established by Council RegulationEEC/2377/90. The EC definition of MRL isvirtually the same as that adopted by CACRVDfor foods. The Annexes to Regulation 2377/90 areas follows:

• Annex I: full MRL can be set;• Annex II: safe, no MRL needed to protect the

consumer;• Annex III: sufficient data to set a provisional

It should be noted that, although no formal MRLregulation has been established in the UnitedStates, the equivalent there is the tolerance, whichis established by the regulatory authorities.

GLOBAL PERSPECTIVEHACCP as a risk-based management tool forantibiotic use in aquaculture. In aquaculture,antibiotics are generally administered in feeds,having been either added during feedmanufacture or surface-coated on to pellets bythe manufacturer or the farmer. During outbreaksof disease, farmers may apply antibiotics usingother routes. Clear instructions are thereforerequired for the feed manufacturers, antibioticdealers, veterinary authorities and farmers whoare responsible for the use of antibiotics. Whoprovides such information, and who isresponsible for regulating and controllingantibiotics nationally?

The Hazard Analysis Critical Control Point(HACCP) system is recommended as a way ofreducing hazards stemming from the processingof fish and fishery products. Implementation ofthe HACCP system in fish processing ismandatory, and all exporting countries have tocomply with this requirement for internationaltrade. Since the middle of 1990, some developedcountries have introduced the system to controlhazards from the use of antibiotics at the pondlevel.30 The introduction of HACCP to controlfood hazards in aquaculture, including thosestemming from the irresponsible use of antibioticshas been widely recommended31 and has beendiscussed by an FAO/Network of AquacultureCentres in Asia-Pacific (NACA)/WHO StudyGroup on Food Safety.32

HACCP is currently not mandated by mostprimary animal production regulations thatinclude aquaculture. In many countries, evenwhen the liability may be shared or (dependingon regulations) when it remains on theproduction side, the actual obligation to controlthe use of antibiotics and their residues rests withthe processing industry, as HACCP is mandatedwithin the processing sector. This createsdifficulties in implementing control measures onantibiotic use in aquaculture.

All the elements for identifying the criticalcontrol points (CCPs) and critical limits ofregulatory requirements exist for approvedantibiotics and veterinary drugs, specific fish orshellfish species, diagnosis (purpose of use), dose,duration of treatment and withdrawal period. Ithas been suggested that the CCP would be at thefeeding stage, since this is when antibiotics areusually introduced into the production process.The analysis of residues of the antibiotics used,and the checking of compliance with regulations,would form part of the verification procedures. Inaddition, as USFDA has suggested, themonitoring of residues in flesh may be notenough, and the development of resistance inpond micro-organisms (and/or the target micro-organism) should also be monitored – anadditional CCP.

Regarding the fish processing industry, furtherprocedures, activities and monitoring should beperformed in addition to the HACCP plan. Inparticular, prerequisites (e.g. plant location, watersupply and effluent control) and good hygienepractices at the pond should be implemented.The storage and handling of antibiotics should beput under a scheme of monitoring, as indicated inthe United States HACCP-based regulation forstorage of chemicals in the plant, for example.33

As with most food hazard-related areas, manypeople are involved in aquaculture hazardmonitoring, including regulators, consumers,producers, processors, journalists and –sometimes – researchers, who may lack acomplete picture of a given risk and itspossibilities of management. The importance ofcommunicating problems widely has beenrecognized.34 Risk communication is a necessarycomponent of antibiotic use for aquaculturepurposes. In some countries, there is aconsiderable lack of information andtransparency, which conspires against the propersolution of possible problems, and eventuallycreates additional ones. Communication with theconsumer is particularly important. A crisis, suchas the one involving chloramphenicol, alters thenational and international fish markets because itfosters consumers’ fears about fish as food.

The proper use of approved antibiotics willcontinue to be necessary in animal production,including aquaculture, and consumers should bereassured that the use of approved antibiotics, inparticular under "label use" conditions, does notimply a hazard. In addition to the public healthproblems that result from people being rendereddefenceless to illnesses caused by antibiotic-resistant bacteria and the residues of bannedantibiotics, there are also economic constraints tobe taken into account.

The future of aquaculture depends, inter alia,on the production of safe and wholesomeproducts, and this goal can be achieved.However, the recent crisis with chloramphenicolindicates that the current situation with regard tothe use of antibiotics is far from satisfactory. Theresponsible use of antibiotics can be achievedthrough implementing adequate risk managementmeasures, including developing and enforcingappropriate regulatory procedures. Theinformation and knowledge base concerning thehazards and risks involved in the use ofantibiotics should be improved, and the risksposed by existing hazards, in particular of drug

supplies and use, should be communicated.Additional efforts are required in the areas ofresearch, training, capacity building, legalframeworks and communication. Aquaculturistsin developing countries should be encouragedalways to seek professional guidance in the use ofantibiotics, particularly from the regulatoryagencies, extension services and qualifiedprofessionals. Where there is no adequateprofessional guidance, countries should embarkon developing the necessary capability, and aidagencies and development partners shouldprovide all necessary assistance to this process.

Application of HACCP-based managementpractices within production systems is central forreducing possible risks. Appropriate guidelinesand technical standards should be developed inconsultation with all stakeholders. There is also aneed to reassure consumers about the safe use ofapproved antibiotics and measures to constrainthe use of banned substances. Relevantinformation should be made readily available tothe general public through various informationdissemination mechanisms.35 Efforts should bemade to restrict the use of antibiotics totherapeutic purposes only.36 Countries should beencouraged to develop and implement moreinternationally harmonized and transparentprocedures for managing and controlling the useof antibiotics in aquaculture.

National or market-area MRLs. National ormarket-area MRLs will continue to exist untilCAC has been able to set MRLs with wideinternational acceptance. However, the CACprocess is slow, so a full range of MRLs will notbe available for many years. If there are science-based national or regional MRLs, and the controlprocedures are based on reasons of consumersafety, claims that trade barriers exist will beunsupportable, provided that the residue controlprogrammes are operated fairly and equivalentlybetween national and imported products.
