Greetings from the Fisheries and Aquatic Sciences Program!

Our program is uniquely comprehensive in its coverage of the fisheries and aquaticsciences and in the best of the Land Grant tradition, it brings cutting-edge science tomany important applied problems. In this issue, we highlight the work of four of ourgraduate students who address problems in oyster restoration, control of invasivelionfish, ornamental aquaculture, and fisheries stock assessment.

Michael Espriella is developing new methods for monitoring intertidal oyster reefs usingunmanned aircraft systems. His particular focus is on image analysis techniques that willvastly improve the speed and efficiency of oyster reef monitoring while also providingnew data on factors that influence reef persistence or decline. This is a great example ofthe rapid advances in habitat and biological monitoring capacity we have achieved byadding expertise in remote sensing and geospatial sciences to our core Program andramping up cross-SFRC collaborations with the Geomatics Program.

Holden Harris is assessing the effectiveness of targeted fishing as a method forcontrolling the abundance of invasive lionfish in the Gulf of Mexico. His research isevaluating the efficacy of novel traps and the impacts of an emerging disease on lionfishpopulations. In addition, he is using bio-economic models to explore the potential for aneconomically viable commercial lionfish fishery.

In the aquaculture area, Taylor Lipscomb is delving deep into the digestive physiologyof fish larvae to understand their nutritional requirements in a critical

developmental period. His research shows that tetra fish larvae can be weaned off live feeds earlier than is currently practiced,potentially resulting in efficiency gains for the ornamental fish industry.

Ashley Pacicco’s research aims to improve our basic knowledge of yellowfin tuna growth and reproductive biology. This workprovides vital information for fisheries stock assessment and management. Ashley is an employee of NOAA Fisheries, based at theirPanama City lab, and she takes advantage of our flexible online classes and a supervisory committee that includes a senior scientistfrom the NOAA lab to obtain a research degree without having to leave her duty station. A win-win-win for her, her employer andour program.

iTag (Integrated Tracking of Aquatic Animals in the Gulf of Mexico), a collaborative movement ecology program led by SueLowerre-Barbieri (research faculty based at the Florida Fish and Wildlife Research Institute) is another example of a highlyproductive agency partnership. Check out the iTAG website to see how the network revolutionizes our ability to monitor mobilemarine organisms.

Please join me in congratulating our recent graduates and the many faculty and students who have been recognized for theiroutstanding work or tapped for important advisory roles. Finally, take a look at the long list of new publications our program hascontributed to the scientific literature over the past months! If you are interested in a listed publication but can’t access it throughan institutional subscription, contact the author and they will send it to you for free!

Thanks for your interest in our program and we hope that you enjoy this issue of WaterWorks! Kai

MICHAELESPRIELLAUsing Unmanned Aircraft Systems to Monitor Intertidal Oyster Reefs

Oyster reefs are declining globally as a result ofstressors such as overharvest, disease, coastaldevelopment, and alterations to naturalfreshwater flow. This decline results in a loss ofecosystem services and affects the livelihoodof coastal communities that rely on the fishery.Oyster reefs provide habitat for hundreds ofother species, filter the surrounding water, andcontrol shoreline erosion. Florida’s Big Bendcoastline presents a unique opportunity tostudy the decline as it is sparsely populated,limiting direct anthropogenic impacts whencompared to other high stress areas. Despitethe absence of typical human-inducedstressors, declines persist in this region makingit a key study area.

Student Research HighlightThe graduate students in the Fisheries and Aquatic Sciences program conduct cutting-edge research, from oysters to lionfish. Read on to learn about four exemplary student projects.

I was intrigued byoyster reefs and

the habitat theyprovide because

the intertidalreefs that line

the Big Bendcoastline are at

the interface ofterrestrial and

aquatic ecosystems.The tidal nature of the

habitat makes it difficult to sample oysterreefs, and sampling methods are often timeand cost-intensive. Unmanned aircraft systems(UASs) allow for rapid collection of sub-centimeter resolution imagery of coastalhabitats at a low cost.

While UASs provide an efficient mechanism tocollect imagery, it is important that the methodof analysis is time efficient as well. I am taking aGeographic Object-Based Image Analysis(GEOBIA) approach to quantify reef coverageand assess reef status. GEOBIA is a semi-automated technique that allows for morerobust analysis than traditional pixel-basedanalysis techniques. It is a two-step process:first pixels are segmented into objects basedon textural, spectral, and spatialcharacteristics, then those meaningful objectsare classified using a ruleset.

Our current study area is Little Trout Creek,located north of Cedar Key and south of themouth of the Suwannee River. Overlapping RGBimagery was collected with a UAS and stitchedtogether to generate an orthomosaic and adigital elevation model. The scene containsmudflats, salt marshes, and oyster reefs.

WATERWORKS | FALL 2019 PAGE 3

Masking out the water is an essentialintermediate step as the spectral similaritybetween the water and reefs causesmisclassifications. After masking out the waterusing a water index (Red-Blue+Green/Red+Blue+Green) and elevation data, theexposed habitats were segmented and readyfor classification. A sample of each habitat wasselected from the imagery to derive terrainattributes from the digital elevation model. Weconducted a multiscale analysis to determinewhich attributes at which scale are best suitedto differentiate between habitats. Once theattributes were selected, they were used alongwith the spectral characteristics to classify thehabitats. This work is continuing, as I look toimprove the classification, especially in areasof sparse oyster coverage, by further exploringthe characteristics that define each habitat.The next step is to conduct this analysis at thescale of an individual reef to identify anystructures that may contribute to reef successor decline. Identifying spatial characteristicsthat contribute to reef success can informmanagement as well as restoration projectsthat may look to mimic the structure ofsuccessful reefs.

HOLDENHARRISViability and Effectiveness of a Commercial Fishery to Mitigate Invasive Lionfish in the Northern Gulf of Mexico

Indo-Pacific red lionfish (Pterois volitans/milescomplex) in the Western Atlantic Ocean havebeen the most successful marine fish invasionon record, causing region-wide negativeeffects on reef fish communities andecosystem processes. Mitigating their impactsis a top priority for marine resource managers;however, suppressing lionfish densities isconfounded by rapid replenishment, source-sink dynamics, and deepwater refuges.Developing lionfish fisheries has beenproposed as market-based solution to controltheir densities and augment commercialfishermen livelihoods. My dissertation researchexamines the potential effectiveness of acommercial lionfish fishery in the northern Gulfof Mexico (nGOM) by studying (1) lionfishdetection and removal efficiency, (2) thepotential for deepwater lionfish traps, (3)population effects from a novel lionfishdisease, and (4) bioeconomic models for acommercial lionfish fishery.

Accounting for detection and removal efficacyis necessary for evaluating lionfishmanagement targets as population-andcommunity-level effects of lionfish removalsmay be diminished by undetected lionfishremaining in the system. My recent work onlionfish detection and removal efficiencyquantified the effectiveness of lionfish surveysand removal efforts (doi.org/10.1016/j.fishres.2019.01.002) quantified. Wefound that previous surveys on nGOM naturalreefs likely underestimated densities, which

may be 3X higher than previouslyreported. Removal efficiency

for spearfishing was 87% onartificial reefs and 67% on

natural reefs, and 47% onCaribbean coral reefs.Incomplete removal

efficiency, in concert withdensity-dependent processes,

may explain recent findings thatsustained lionfish removal efforts

had no discernible positive impacts onnative reef fish communities.

To date, the capacity to control lionfish hasprimarily been from spearfishing using open-circuit SCUBA. However, most of the invadedrange is in mesophotic depths (> 40 m)inaccessible to divers and where lionfishdensities are higher. Lionfish traps have beenproposed as a means to remove deepwaterlionfish. I developed and tested traps on nGOMartificial reefs (nwdistrict.ifas.ufl.edu//2018/),and recently completed fieldwork thatexamined the effectiveness of three trapdesigns – Florida lobster traps, Atlantic seabass pots, and Gittings purse traps (Fig. 1) – toremove lionfish biomass from mesophoticreefs while assessing potential impacts tonative reef fishes.

WATERWORKS | FALL 2019 PAGE 5

Preliminary results suggest the Gittings pursetraps are the best choice for lionfish removal,but that further research and development willlikely be necessary to prevent bycatch issuesand increase catch rates.

High population densities and low geneticdiversity in their invaded range suggest lionfishcould be vulnerable to pathogenic control. Wereported the first observed disease in invasivelionfish found in fish harvested in the nGOM insummer 2017 which appeared to spreadthroughout the invaded range.(edis.ifas.ufl.edu/fa209). Following the diseaseemergence, we observed changes in lionfishpopulations. Population surveys indicatedmean lionfish density declined approximately75% on high density artificial reefs, 55% on lowdensity artificial reefs, and 75% on natural reefsin 2018 (Fig 2a). Regional commercial lionfishspearfishing landings and catch per unit effort(CPUE) concurrently declined (Fig 2b).Collectively, these results provide evidence fordensity-dependent epizootic populationcontrol and have implications for lionfishmanagement strategies.

Findings from the work above will help medevelop bioeconomic models for a commerciallionfish fishery. Lionfish fisheries are openaccess (i.e., having little or no regulations),

which are economically inefficient becausethey don’t create surplus profit. Paradoxically,efforts to overfish lionfish decreases harvesterprofitability. Bioeconomic models of a lionfishfishery allow evaluation of effort levels wherefishing effort and harvest will cause overfishing(i.e., population control) and the stock levelswhere harvesters would be expected enter orexit the fishery. These models will be used toconsider challenges and solutions for a long-term, market-based fishery. My work aims toassist fisheries managers and commercialfishermen by understanding the economicprocesses and ecological effects of a novelinvasive species fishery.

TAYLORLIPSCOMBHistological, Histochemical and Biochemical Characterization of Larval Digestive System Ontogeny in Two Characid Species to Inform Weaning Protocols

Among the many challengesencountered during theproduction of freshwaterornamental fish, larvalnutrition persists as abottleneck. Limitedsurvival, abbreviatedgrowth and apparentdependence on live feedsare all characteristic ofThis life stage in manyornamental fishes. A significant

amount of the ornamental larvae rearedintensively upon first feeding are fed newly-hatched Artemia franciscana (brine shrimp)nauplii, which is costly and has inconsistentavailability. Members of the family Characidae,and particularly tetras, appear to require livefeeds for larval propagation. Live feeds exhibitdisadvantages relative to preparedmicroparticulate diets (MDs), specificallypertaining to availability, labor, and cost.

I approached this problem by first directlyevaluating the dependence of these species onlive feeds at the onset of exogenous nutrition.After 10 days of feeding beginning at firstfeeding, Larval Black Tetra Gymnocorymbusternetzi and Neon Tetra Paracheirodon innesiindeed exhibited poor survival and growthfrom MDs relative to Artemia. Following thisconfirmation of live feed dependence, I

characterized the digestive system ontogenyof each species using histology,histochemistry, and biochemical analysis ofdigestive enzyme activities from the onset ofexogenous feeding through the larval stage.Both species exhibited an agastric, altriciallarval stage, as well as low digestive enzymeactivity at the onset of exogenous feedingfollowed by abrupt increases in trypsin, lipase,and pepsin activity. In P. innesi, histologicaldifferentiation of the stomach, includinggastric gland formation and production ofneutral mucopolysaccharides, as well as theonset of pepsin activity, did not occur until 20days post hatch (dph). For G. ternetzi, these

developmental milestones were not reacheduntil 22 dph. This shift from agastric to

gastric digestive modes is indicative of aproliferation of digestive capacity andsubsequent prey diversity.

Based on this information, experimentswere conducted to evaluate different

weaning times from Artemia to a MD. Foreach species, twenty replicate tanks were fedArtemia exclusively from hatch through theend of the trial, a MD exclusively, or weretransitioned from Artemia to a MD at threedifferent timepoints. For P. innesi fed until 32dph, and weaning beginning at 12 dph and 17dph, survival was similar to live Artemia (mean:22.0 ± 1.7%), while weaning beginning at 22dph resulted in lower survival (16.2 ± 1.3%); MDonly resulted in the lowest survival (0.8 ±0.3%). For G. ternetzi fed until 33 dph, weaningbeginning at 13 dph exhibited higher survival(20.6 ± 1.8%) than live Artemia and weaningbeginning at 18 dph and 23 dph (mean: 13.6 ±1.5%), while the MD resulted in the lowestsurvival (0.8 ± 0.2%). For both species,weaning did not result in statistically highergrowth than Artemia. These results indicatethat weaning is possible prior to gastricdifferentiation, potentially resulting in thereduction of Artemia use in the larval culture ofboth characid species.

ASHLEYPACICCOAge, growth, and reproduction of

Yellowfin Tuna in the Gulf of Mexico and U.S. Atlantic

Yellowfin Tuna Thunnus albacares is a highlymigratory species found in tropical andsubtropical oceans around the world. Highlyvalued as a food source, Yellowfin Tunasupports lucrative commercial and recreationalfisheries. Yellowfin Tuna in the Atlantic aremanaged as a single stock by the InternationalCommission for the Conservation of AtlanticTunas (ICCAT). The northern Gulf of Mexico offthe mouth of the Mississippi River is anespecially productive area for Yellowfin Tuna,with oil platforms acting as fish aggregatingdevices (FADs). Despite its economicimportance, basic life history information forthe species from U.S. waters is limited. The goalof my research is to address key uncertaintiesin the growth and reproductive biology ofYellowfin Tuna in U.S. waters to better informstock assessment and ultimately to improvethe management of the Yellowfin Tuna Atlanticstock.

My first research objective focuses onYellowfin Tuna age, growth, and longevity.Through a collaborative effort with theNational Marine Fisheries Service (NMFS) inPanama City, FL, and the Louisiana Departmentof Fish and Wildlife (LDFW), over 3,000Yellowfin Tuna sagittal otoliths (“ear stones”)were collected during 2004-2017 by at-sea ordockside samplers throughout the U.S. Atlanticand Gulf of Mexico, mostly from therecreational or commercial fishery. These fishwere also measured and ranged in size from

636-1901 mm curvedfork length (CFL).

To age the fish,their otolithswere sectionedthrough the

core using alow speed saw

and annual growthincrements (annuli

or “rings”) were countedas successive opaque and

translucent zones (Figure 1). Estimated agesranged from 1 to 18 years old, which surpassesthe current longevity estimate of 11 yearsused in previous stock assessments for theAtlantic Ocean. An increased estimate oflongevity for Yellowfin Tuna directly impactsestimates of natural mortality (mortality notcaused by fishing). Longer-lived species tendto have lower natural mortality and arepotentially more susceptible to fishingpressure. The length of each fish combinedwith its age estimate was then used to modelgrowth of Yellowfin Tuna using a vonBertalanffy growth model. Growth was similarbetween males and females until the onset ofsexual maturity and then males reached alarger size than females (Figure 2).

WATERWORKS | FALL 2019 PAGE 9

My second research objective focuses on thereproductive biology of Yellowfin Tuna byestimating the spawning season, the size andage that females reach sexual maturity,spawning frequency, and batch fecundity(estimate of the number of eggs releasedduring a spawning event). Of the fish collectedfor the age and growth study, 469 ovaries werealso collected and preserved. Histologicalsections were then taken for each ovary, whichshows the microscopic structure of individualeggs in the ovary. I assigned ovaries to areproductive stage (immature, developing,spawning capable, actively spawning,regressing, regenerating) and found that theyhave the potential to spawn nearly year-round,but peak spawning occurs during May-August.Yellowfin Tuna are also batch spawners, whichmeans that they spawn multiple times duringthe same reproductive season. Females havethe potential to spawn almost daily, with anestimated spawning frequency of 1.7 days.They spawn an average of 3.3 million hydratedeggs per batch, with higher estimates observedin larger, older females. Estimates of spawningfrequency and fecundity aid in determining thespawning potential of the population.Estimated length at 50% sexual maturity was1098 mm CFL for females. Whole ovary weightdid not increase relative to CFL until femalesreached ~1180 mm, which aligned with the

assignment of females in spawning condition(Figure 3).

Basic life history data can continue to beimproved and used by ICCAT in future stockassessments to ensure the long termsustainability of Atlantic Yellowfin Tuna.

iTAG Launches New Website for Marine Animal Tracking

Faculty Tapped for Aquaculture Expertise

Craig Watson and Cortney Ohs from the Tropical Aquaculture Lab were appointed to

the Technical Advisory Committee for the USDA Southern Regional Aquaculture Center

(SRAC) representing Florida and UF. Their participation, along with Marty Tanner of

Segrest Farms and Aquatica, assures that the issues and needs of Florida’s producers are

considered in SRAC programs.

FAS UPDATES

Animal migrations are some of the most dramatic natural events on the planet, from wildebeest on the Serengeti to monarch butterflies traveling to Mexico. In fish, an iconic example of migration is salmon returning to their birth sites in huge numbers to spawn before they die. However, there are still many unknowns in marine animal movement patterns, as their travel occurs underwater and often far offshore. Sue Lowerre-Barbieri hopes to change this through a collaborative movement ecology research program, iTAG (Integrated Tracking of Aquatic Animals in the Gulf of Mexico).

With more than 100 current members from the US, Mexico, Cuba and the Caribbean, the program has already collected more than 11 million “detections” of tagged marine animals. Members using acoustic tracking methods can upload detected species data directly to the site. Researchers can search the database for their own tag numbers to see where their tagged species have traveled.

FAS/FWC Fishing Tournament Results

When Dr. Bill Seaman retired in 2006, it was important to him that he retired “to something” instead of “from something.”

“As a faculty member, I was so fortunate to have done something that I loved. I wanted to use my time in retirement

to give back as much as I could,” said Bill.

Bill still remains involved in academia, and regularly consults with faculty. He also writes a monthly science column for his

local newspaper and published the “Encyclopedia of Ocean Sciences: Artificial Reefs” in 2019.

However, Bill has recently discovered a new passion for environmental education, working with new audiences in his

community of Montreat, North Carolina.

FAS UPDATES

The 23rd Annual UF Fisheries and Aquatic Sciences – FWC Fishing Tournament is complete!We had a total of 10 boats and 30 anglers this year.

Anglers were greeted with excellent weather, which allowed boats to venture out to Seahorse Reef by mid-morning and spread throughout the Cedar Key/Waccasassa/Suwannee area.

Largest Redfish – Jason Dotson, 26.75 inches. Really a perfect tournament fish that

he and Drew Dutterer brought in this year.

Largest Spotted Seatrout – 17-year old Trey Stanfield, fishing with Mike Allen, Natalie Allen

and Chris Wynn. This was the first tournament that Trey has ever fished, and

he came out a winner with a really fat 20-inch trout.

Largest Mackerel – George Tanner, 24 inches. George’s boat again had an excellent

catch of Spanish Mackerel from Seahorse Reef.

Most Impressive Cooler AND Largest Cobia–Jason “Mo” Bennett and Steve Larsen. These guys have been fishing the tournament for close to 20 years, and this year they had a banner day with 8 Spanish Mackerel, one nice Seatrout, and a 42-inch Cobia to top it off. They found the Cobia swimming near a large Tiger Shark out on Seahorse Reef. Mo’s son Jace was on board as well!
