| New England Aquarium Corporation | Title: Post-release mortality and behavioral recovery of bull sharks (Carcharhinus leucas) caught in the U.S. South recreational shark fishery Synopsis: Although the aggregated large coastal shark (LCS) group consists of several species governed by the same landing regulations, evidence suggests that post-release mortality (PRM) rates are highly species- and fishery-specific. Such variability highlights the need to understand and account for PRM in species-specific stock assessments and management plans. Few PRM investigations have taken place in the recreational shark (rod-and-reel) fishery for LCS species, and none have focused on three species scheduled for upcoming stock assessments: bull, finetooth, and tiger sharks. Bull sharks are of particular concern because they have the highest fishery-interaction rates of these species, with annual recreational discards averaging 22 and 38 times more than finetooth and tiger sharks over the past five years. Although survival data from general telemetry studies are often used in assessments if no PRM rates are available, these data are inappropriate since such studies typically use gear that does not simulate the fishery and select only the healthiest animals for tagging and monitoring. Considering the high discard rates of bull sharks and lack of mortality data, coupled with the growing popularity of recreational shark fishing, there is a clear need to directly investigate bull shark PRM in the recreational fishery to effectively manage this species. To address this problem, we propose a cooperative tagging project aimed at enhancing our understanding of the impact of recreational fishing on bull sharks. This project will involve working closely with charter captains throughout the U.S. South Atlantic and the Gulf of Mexico to capture and satellite tag sharks. Capture information and tag-derived movement data will be used to estimate PRM in the recreational fishery and identify the capture characteristics (i.e., fishing conditions and practices and biological traits) driving the recovery and mortality of sharks discarded in this fishery. The information provided by our project will be an important, proactive step toward properly managing bull sharks and is particularly timely given this species’ upcoming stock assessment. In addition, this project will provide much-needed financial support to our recreational fishing industry partners in Southwest Florida (i.e., through hired charter trips and tagging compensation) that were directly impacted by Hurricane Ian.

| University of Southern Mississippi | Title: Collection of Critical Life History Data for Bull Sharks (Carcharhinus leucas) in the U.S. Gulf of Mexico and South Atlantic Synopsis: The proposed project will investigate the life history of bull sharks in the northern Gulf of Mexico and U.S. South Atlantic to generate updated life history parameters necessary for continued management and sustainability of this species. Specifically, this study will collect immature and mature bull sharks on a monthly basis to fully describe the seasonal reproductive biology of this species and provide updated age and growth estimates. Sharks will be obtained through collaborations with 1) established commercial shark fishers in the northern Gulf of Mexico who consistently encounters all life stages of bull sharks during routine fishing operations; 2) established port sampling of the shark fishery in Venice, LA; 3) NOAA Apex Predators Program who are collecting samples from the Research Shark Fishery’s Observer Program and opportunistically from the NEFSC Coastal Shark Bottom Longline Survey, primarily in the U.S. Atlantic, and have approximately 300 archived vertebra for age and growth analysis, and 4) SEAMAP bottom longline, GULFSPAN, and COASTSPAN survey partners in TX, LA, MS, AL, FL, GA, SC, DE. Analysis of the data collected during this study will document 1) reproductive seasonality; 2) reproductive periodicity; 3) gestation period; 4) time of parturition; 5) size and age-based maturity ogives by sex; 6) brood size vs. maternal size and age relationships; 7) weight-length relationships by sex; 8) age and growth estimates; and 9) theoretical longevity. The anticipated results from this study can be directly utilized by the SEDAR panel for the benchmark stock assessment slated for 2024, and continued management of this species. Further, this study will be the first full reproductive assessment and will update age and growth estimates for this species in U.S. waters. PI: Jeremy Higgs (NA22NMF4540120) |

| New England Aquarium Corporation | Title: Post-release mortality and misidentification of a large coastal shark species, the spinner shark (Carcharhinus brevipinna), in the U.S. Southeast recreational shark fishery Synopsis: The aggregated large coastal shark (LCS) group consists of several species governed by the same rules, but we know some of these species are likely to be more resilient than others. For instance, recent evidence suggests highly variable post-release mortality (PRM) rates between LCS species in commercial longline fisheries. This variability in PRM points to a need for species-specific stock assessments and management plans. An LCS species of particular concern is the spinner shark (Carcharhinus brevipinna). Spinner sharks are one of the most commonly caught LCS species in the recreational shark fishery and were recently shown to have the highest PRM rates of any LCS species caught in the bottom longline fishery. Therefore, spinner sharks may be the most vulnerable LCS species, requiring species-specific assessments and data. Despite this concern, as the bottom longline fishery in the Southeast region declines and the impact of recreational fishing is becoming magnified, no study to date has quantified the rate of spinner shark PRM after being caught on rod-and-reel. Adding to this concern is how frequently spinner sharks are misidentified in this fishery due to their similarity with blacktip sharks. Misidentification is problematic because it can lead to under-reporting of catch and an unaccounted source of fishing mortality that would hinder stock assessments and management. However, misidentification rates have yet to be quantified in the fisheries-dependent surveys used to estimate catches in the recreational fishery. Taken together, spinner sharks represent a susceptible LCS species that may be subject to high PRM and under-reported catch rates in the recreational fishing industry. To address this problem, we propose a cooperative tagging PRM project combined with an investigation of species misidentification rates to greatly enhance our understanding of the impact of recreational fishing on this species. Specifically, we will provide estimates of spinner shark PRM in the recreational fishery and identify capture characteristics driving mortality. We will also employ a novel approach to quantifying the species misidentification rate, which can be used as a correction factor for misidentification in fishery-dependent catch surveys. The information provided by our proposed project will be an important, proactive step towards properly managing this potentially susceptible species. PI: Ryan J. Knotek, Nicholas W.

| University of Maine System acting through Univ. of Maine | Title: VALIDATED LIFE HISTORIES OF ATLANTIC PELAGIC FISHES - BOMB RADOCARBON DATING OF SWORDFISH, BLUE MARLIN AND ALBACORE TUNA Synopsis: Stock assessments rely on a fundamental understanding of life history (age, growth, maturity, mortality), but this information requires validation and quality control to ensure the data provided reflects stock dynamics and does not jeopardize long-term sustainability. Life history information is often incomplete or unknown for highly migratory species. The aim of this project is to use a well-developed reference system for age validation of blue marlin broadbill swordfish and northern albacore tuna to provide valid life history characteristics essential for sustainable fisheries management. A state-of-the-art method used to address these concerns called bomb radiocarbon dating has been refined over the last 30 years. Technological improvements, coupled with insight on the propagation of the bomb-produced signal in aquatic ecosystems, are now available to resolve age estimation issues for challenging fishes, and specifically for recently collected, fast-growing pelagic fishes. We propose to use well-established North Atlantic bomb references to test the validity of age estimates for these ecologically and economically important fishes of the North Atlantic by comparing measured values using novel gas-AMS (accelerator mass spectrometry) technology at ETH Zürich from otoliths of aged fish with regional temporal references. Further, we will develop a sampling program and standardized protocols based on validated growth zone structure to provide age estimates. PI: Walter J. Golet (NA22NMF4540119) |

| University of South Carolina | Title: Data-Poor Caribbean Reef Fishes: Addressing Critical Gaps in Yellowtail Snapper Age, Growth, and Reproduction for Puerto Rico and St. Thomas/St. John, USVI Synopsis: Reef fishes have been utilized as food fish in U.S. Caribbean waters for centuries, with increasing fishing efforts in recent decades. As a result, many species have experienced declines in landings, including yellowtail snapper Ocyurus chrysurus. However, little to no peer-reviewed published research exists on basic life history parameters for the U.S. Caribbean populations. Currently, yellowtail snapper ranks as one of the top three commercial reef fishes landed for two out of the three U.S. Caribbean Island Management Platforms and two separate stock assessments are scheduled for yellowtail snapper in the U.S. Caribbean: one for the Puerto Rico (PR) and one for St. Thomas/St. John (STT/J). The 2022 CRP notice of funding states, “Stocks managed under the Magnuson-Stevens Act are top priority, and we encourage research that can be utilized in upcoming stock assessments.” The notice identifies yellowtail snapper as a Caribbean Fishery Management Council Priority Species. The focus of our proposed collaborative investigation is to improve life history information for this data-poor species in support of providing comprehensive life history information on yellowtail snapper from PR and STT/J for two upcoming stock assessments.

| Virginia Polytechnic Institute and State University | Title: Early growth and maturity data collection for blueline tilefish along the U.S. Atlantic Synopsis: Blueline tilefish (Caulolatilus microps) is a data limited species with its early growth and reproductive biology of serious concern in a recent SEDAR review due to low sample sizes of early life stages and limited spatial coverage. Both the mean age and length of both males and females of blueline titlefish have been found to vary over time and space but lacking younger fishes causes difficulty in both individual growth dynamics modeling and maturity analysis, which influence its population dynamics and stock assessment and cause large uncertainty and high concern in its fisheries management. In order to improve tilefish stock assessment, SEDAR50 and the Fishery Performance Report both highly recommended the urgent need for biological data collection and the spatial coverage of its sample collection. Blueline tilefish create and live in burrows. Currently used gears for multi-species fishery independent surveys are found not appropriate for such species. Partnership survey by cooperating with industry seems the best available approach in this case, which meets the spirit of the CRP program. We propose a survey by cooperating with experienced charter boat hook-line fishermen to collect reproductive samples cross sizes and space, to estimate its early maturation status and growth. The proposed study will be directly applicable to the blueline tilefish stock assessments. PI: Dr. Yan Jiao (NA21NMF4540280) |

| Mote Marine Laboratory, Inc. | Title: Leveraging Electronic Monitoring in the Gulf of Mexico Reef Fish Fishery for an Innovative Minimal Human-Contact Collection of Biological Samples from Data-Poor Species Synopsis: The Mote Marine Laboratory (MML), Center for Fisheries Electronic Monitoring (CFEMM), with established collaborations with industry, providers of Electronic Monitoring (EM) equipment and software, and state and federal management agencies, have spearheaded EM to monitor and document catch, bycatch, and discards in the snapper grouper fishery. In this capacity, the proposed project responds to the NOAANMFS Cooperative Research Projects (CRP) foremost priority to “provide usable and relevant information to aid fishery researchers, scientists, and managers to make informed decisions” for the effective management and conservation of reef fish resources in the GoM.

| Florida Atlantic University | Title: Using a citizen-science approach to characterize shark depredation in the recreational fisheries of the southeast United States Synopsis: Shark depredation is an emerging issue that is purportedly affecting several non-HMS (snapper-grouper, coastal migratory pelagic, dolphin/wahoo) as well as select HMS (e.g., tunas and billfishes) fisheries in the southeastern US. While the NOAA Office of Sustainable Fisheries recently produced a report on shark depredation in commercial fisheries (i.e., pelagic/bottom/vertical longlines), there have been no attempts to quantify these interactions in recreational fisheries that heavily support the economies of this region. As indicated in the recent HMS AP meeting, these data are sorely needed to characterize the scale of the issue and determine the need for (and types of) mitigation measures. However, characterization of this issue is impossible without stakeholder involvement. Here, we propose a citizen-science based approach to 1) acquire depredation data (composition, frequency, etc.) in the recreational sector via leveraging our existing fishing partnerships, and 2) evaluate fishermen perceptions of the issue.

| Texas A&M University Galveston | Title: Life history and age validation of blacktip sharks (Carcharhinus limbatus) in the Gulf of Mexico with implications for stock assessment models - Synopsis: The blacktip shark, Carcharhinus limbatus, is an important target of recreational and commercial fisheries in the Gulf of Mexico (Gulf). In the most recent Gulf blacktip shark stock assessment, several data gaps were identified and research recommendations included a need to examine life history of blacktip sharks in the western Gulf including age, growth, and reproduction. In addition, a benchmark assessment was recommended to treat blacktip sharks in the eastern and western Gulf, highlighting the importance of a comparative life history study within the Gulf. Consequently, the goals of the proposed project are to obtain updated life history parameters for blacktip sharks in both the eastern and western Gulf and incorporate a novel approach to validate the ages of blacktip sharks. outcomes.

| University of Florida | Title: Estimating Gulf of Mexico gray triggerfish release mortality and its mitigation with three-dimensional acoustic telemetry - Synopsis: The goal of this study is to estimate release mortality of gray triggerfish in the northern Gulf of Mexico and test the efficacy of different approaches to mitigate release mortality and its effects on this valuable fisheries resource. Specific objectives of the study are to 1) employ three-dimensional (3D) acoustic telemetry to estimate the fate (e.g., survival, mortality, depredation, emigration, etc.) of gray triggerfish captured with standard recreational fishing gear in the nGOM; 2) estimate the efficacy of descender devices or venting to mitigate release mortality; and, 3) conduct stock assessment simulations to estimate the effect of updated release mortality estimates, as well as the mitigation of release mortality by descender devices or venting, on gray triggerfish stock status and rebuilding timelines.

| Florida Fish and Wildlife Conservation Commission | Title: Estimating adult Red Drum spawning population abundance and recovery after a lethal red tide event in central west Florida - Synopsis: This study continues research begun in 2019 to assess the impact of the lethal 2018 red tide bloom which coincided in space and time with Red Drum spawning aggregation sites in central west Florida. Because Red Drum adults and recruits move to these sites to spawn in the fall, there is potential that the 2018 red tide caused catastrophic mortality that could impact the stock and inshore fishing for years. Our research prior to red tide genetically profiled 8,888 adult Red Drum, providing a rare opportunity for us to quantify changes in abundance post-red tide and track recovery. Multiple years of data are needed to accurately evaluate the 2018 red tide impacts on the Red Drum stock. Specific project objectives include: (1) non-lethally sampling large numbers of Red Drum by purse seine over multiple years with proven methods to collect genetic recapture data; (2) continue to acoustically track 100 Red Drum to independently assess availability to capture and stock structure; (3) conduct annual aerial surveys to evaluate the number, size, and location of post-red tide Red Drum aggregations; and (4) integrate this data into an open population CMR model to estimate Red Drum spawning population abundance and annual variability.

| Mote Marine Laboratory, Inc. | Title: Functional electronic monitoring of the Gulf of Mexico reef fish fishery, Phase II:Tactical assessment of bycatch, discards, and community structure including highly migratory - Synopsis: The proposed work is Phase II of a NOAA-NMFS Cooperative Research Program (CRP) funded project that is proving highly successful and efficient in providing improved bycatch and discard data in the U.S. Gulf of Mexico (GOM) reef fish fishery in the southeast region through the application of Electronic Monitoring (EM) video imaging technology. The Mote Marine Laboratory (MML), Center for Fisheries Electronic Monitoring at Mote (CFEMM), with collaborations with invested partners in industry, EM equipment and software providers, and state and federal management agencies, have spearheaded EM as an effective method to monitor and document catch including bycatch, and discards in this fishery, with particular emphasis on documenting shark bycatch. Phase II of this project leverages a recent CFEMM increase of EM industry involvement and expansion of EM Gulf coverage from the current CRP Phase I project concentration in the eastern GOM to the western and northwestern GOM, totaling more than 56,000 sq. miles.

| University of Florida | Title: Reef fish aging error: Implications for stock assessment, management, and sustainability - Synopsis: The overall goal of this study is to examine the effect of aging error reduction on scientific uncertainty in Gulf of Mexico reef fish stock assessments. It constitutes the second year of a planned 2 -year CRP-funded project and will build on results from current year-1 CRP funding. The objectives to be accomplished with year-2 funding are to 1) test the accuracy of age estimates derived from Fourier transformed-near infrared spectroscopy (FT-NIRS) of red and vermilion snapper whole otoliths; 2) validate age estimation in scamp ahead of its 2020 stock assessment; and 3) conduct stock assessment simulations for vermilion snapper and gray triggerfish to evaluate approaches designed with year-1 funds to decrease aging error, thus lower scientific uncertainty and increase stock assessment efficiency.

Current post-release mortality rate estimates used in stock assessment models are derived from boat-based shark fisheries, which differ from shore-based fisheries that expose sharks to shallow, warm water where air exposure may be prolonged. The Texas coast encompasses one of the largest shore-based fisheries for sharks in the U.S., and PI’s have established robust cooperative relationships with shore-based recreational shark fishermen.

| Florida Fish and Wildlife Conservation Commission | Title: Assessing the impact of red tide on the Red Drum spawning population off central west Florida - Synopsis: This study will assess the impact of an intense red tide bloom on the Red Drum spawning population off central west Florida. The bloom began in October 2017 in nearshore waters off Sarasota, Florida and as of September 2018 has continued at concentrations lethal to fish but spread to now encompass both major Red Drum spawning aggregation sites off Tampa Bay and Charlotte Harbor. Because Red Drum adults and recruits move to these sites to spawn in the fall, there is potential for catastrophic mortality. Because of previous research using genetically profiled fish to estimate abundance, we have the opportunity to evaluate how this red tide has affected spawning population abundance.

| North Carolina State University | Title: Testing the effectiveness of simple tools to increase the post-release survival of black sea bass in the U.S. South Atlantic hook and line fishery - Synopsis: We will use capture-mark-recapture to determine whether release tools increase rates of post-release survival of black sea bass caught from deepwater habitats in the U.S. South Atlantic. There is high uncertainty regarding the effectiveness of different release tools (venting vs. descending) and we are not aware of work that has compared different venting tools. Existing literature recommends species-specific research to determine the effectiveness of these devices. It is logical that we work on black sea bass given the high percentage of releases (relative to fish captured) in the U.S. South Atlantic recreational fishery.

This project will optimize standardized gear deployment while using both research and commercial vessels to cover a range from South Carolina to St. Lucie Inlet, Florida. Selected industry partners will fish in a standardized manner, while their catch and effort, which will be used for catch-per-unit-effort (CPUE) calculations, are monitored by at-sea biologists. The biologists and collaborators from cooperating state agencies will work-up and record data for life history information, including length and weight measurements and remove tissues for life-history studies. Environmental data will be obtained at each gear deployment which can later be used for catch standardization procedures. 1. Optimize gear and survey design of a critical long-term fisheries independent long bottom longline survey for deep-water snapper-grouper species in the U.S. South Atlantic, specifically targeting Golden and Blueline Tilefish. 2. Assess calibration between the gear traditionally used for this survey and the new method developed, so as to maintain the integrity of this long-time series. 3. Provide critical life history data for deep-water snapper-grouper species. PI: Dr. Walter J. Bubley (NA18NMF4540078) |

| New England Aquarium Corporation | Title: New England Aquarium - Post-release mortality of small coastal sharks: providing high-priority data using a cost-effective technique - Synopsis: Assessing the post-release mortality of fish that are caught and released is an expensive endeavor typically requiring a huge investment of resources for minimal return. This project seeks to change that dynamic by taking a cutting-edge new tool, the acceleration data-logger (ADL), and applying it to a small coastal shark for the first time. The PIs have already spearheaded the application of this technology to assess post-release outcomes, and are obtaining such data for large coastal sharks with unprecedented cost-efficiency in ongoing NOAA-funded work with commercial longliners. This project will utilize a newly developed, smaller version of this tag package to assess the post-release mortality and effect of hook type in the blacknose shark, Carcharhinus acronotus, an overfished species of concern for which post-release mortality rates are unknown. This project directly addresses CRP Program Priority 5.a: provide estimates of post-release mortality of all HMS across gear types, focusing on species that are frequently caught as bycatch. It also focuses on an HMS species that was recently deemed overfished, with overfishing occurring. The proposed study would be the first to quantify post-release mortality and behavioral effects of capture on blacknose sharks. This will be accomplished by working with professional charterboat captains to tag animals with ADLs that record depth, temperature, tailbeat movements, and body posture at sub-second intervals, and therefore provide high-resolution information about mortality, swimming abnormalities, and recovery time. ADL data will be compared against capture indices and blood-based stress indicators (e.g., lactate, pCO2, and blood pH) to close the loop between these measures and actual mortality or recovery time. Because ADLs are less expensive than satellite tags and can be reused multiple times, our technique allows us to obtain large sample sizes at a fraction of the cost of other methods. To do this work, we have assembled an experienced team of recreational fishing captains representing the Gulf and Atlantic Coasts in the Southeast Region, and a scientific team that pairs young researchers employing cutting-edge technology with seasoned experts in shark fisheries and post-release mortality studies. Our team is thus uniquely qualified to deliver these high-priority data with unparalleled cost-efficiency. PI: Dr. Nicholas Whitney (NA18NMF4540079) |

Title: Reef fish aging error: Implications for stock assessment, management, and sustainability - Synopsis: The objectives of this study are to 1) examine the relationship between otolith mass and age estimates for red and vermilion snappers and test whether otolith mass more accurately reflects age than does fish length; 2) examine otolith- based aging error in vermilion snapper via application of the bomb radiocarbon chronometer to eye lens nuclei 14C signatures; and, 3) examine aging error in gray triggerfish via comparisons of age estimates derived from dorsal spines versus otoliths and then applying the bomb radiocarbon chronometer to eye lens nuclei 14C signatures for an unbiased estimate of birth year. Red snapper results will be incorporated in stock assessment simulations to estimate the increase in assessment efficiency, as well as effects on estimates of scientific uncertainty. Assessment simulations for vermilion snapper and gray triggerfish results will be accomplished with the second year of CRP funding to be applied for in FY19. PI: Dr. Will Patterson (NA18NMF4540080) |

| South Carolina Department of Natural Resources | Title: Combining acoustic telemetry and pop-up satellite archival tagging to improve data on cobia (Rachycentron canadum) migratory behavior and stock structure - Synopsis: Cobia (Rachycentron canadum) support a popular and growing recreational fishery in the southeastern United States. Recent changes to the fishery management plan (FMP) established Gulf of Mexico and South Atlantic migratory groups with a stock boundary at the Dade/Monroe County line in Florida. Subsequent population genetics and conventional tagging analyses disputed this location and Amendment 20B to the FMP (2015) placed the new stock boundary at the Florida/Georgia line and resulted in a reallocation of the annual catch limit (ACL). Harvest of the Atlantic migratory group (Georgia-New York) has exceeded the ACL by over 200% in each of 2015 and 2016, resulting in shortening of fishing seasons and seasonal closures. We propose to utilize our extensive network of charter guides in order to tag 27 cobia in NC, SC, GA, AND FL with a combination of acoustic telemetry and pop-up satellite archival tags (PSATs) that will collect data on fish both within and beyond the reach of our extensive network of arrays. Additionally, PSAT tags will collect depth and temperature profiles to provide previously unavailable data on cobia behavior. The proposed effort will continue to collect data from the aforementioned telemetry project and synthesize results with the new tagging efforts. The project specifically relates to stated program priorities: 1.b; Developing methods to increase at-sea observations to obtain life history information and (e.g., otoliths for aging, gonads for maturity/fecundity), genetic material, or stomach contents for trophic level information and 1.j.

This study epitomizes the stated main premise for CRP projects, “to provide usable and relevant Information to aid fishery researchers, scientists, and managers to make informed management decisions,” in that our findings will absolutely provide useable and relevant information to aid fisheries management decisions for a CFMC-identified priority species that is also one of SEDAR 46 data-limited species; 2. Specifically, this research addresses Priority 1d. Data collection sampling methodology projects to improve life history information on commercial and recreational finfish and elasmobranch species. Improved information about the age-structure of the catch (both retained and discarded), based on otoliths, vertebrae, spine or other hard-part aging techniques, will provide insight on a stock's resilience to fishing. Improved information on the reproductive characteristics of the stock, including the relationship between size or age and reproductive capacity, will provide information to refine estimates of long-term biological productivity of the stock; and 4f.

| North Carolina State University | Title: Evaluating The Impact of Marine Protected Areas on Population of Deepwater Reef Species Using a BACI Approach - Synopsis: Considerable uncertainty exists regarding the status of deepwater (>60m) reef fish species (e.g. snappers & groupers) in the South Atlantic Bight. Such fishes along the outer continental shelf have been difficult to sample due to the patchiness of high-relief productive habitat and lack of knowledge of what constitutes good habitat for each deepwater species. Spatial closures such as Marine Protected Areas (MPAs) are widely considered the most effective means of managing stocks of rare or depleted fish species (short of full-scale regional multi-species closures). However, the effectiveness of MPAs in restoring overfished stocks of deepwater reef fishes in the US southeast is unknown. PI: Dr. Jeffrey A. Buckel (NA17NMF4540138) |

Evaluate if and how the relative abundance of Red Snapper in the U.S. South Atlantic has changed during an ongoing fishing moratorium. Assess, to what degree, the spatial dynamics of Red Snapper in the U.S. South Atlantic has changed during an ongoing fishing moratorium.

Title: Development of a pregnancy test for characterizing of reproductive biology in commercially and recreationally exploited sharks - Synopsis: The large coastal shark (LCS) and small coastal shark (SCS) fishery complexes are multispecies stocks respectively composed of 11 and 4 species of commercially and recreationally exploited sharks, several of which have been shown to be overfished in recent federal stock assessments. This has motivated a greater need for careful management of these fisheries based on reliable life history data. Unfortunately, information on the life history of some of these species – especially in Atlantic waters – is incomplete, conflicting, and/or potentially outdated, complicating the management process. For example, fishery managers have identified the evaluation or reevaluation of the reproductive biology of Atlantic populations of several LCS and SCS (e.g., bonnetheads, blacknose sharks, finetooth sharks, sandbar sharks, hammerhead sharks) as priority research necessary for improved management of these species. However, at the same time, there is a growing interest in using more conservation-minded, non-lethal approaches for characterizing the reproductive biology of sharks, such as the measurement of plasma concentrations of gonadal steroid hormones as a surrogate for conducting morphological assessments of the reproductive tract. Still, while these methods show promise for identifying certain reproductive stages in these fish (e.g., testosterone levels reflect sperm production in male sharks), they are largely ineffective for detecting pregnancy in female sharks and obtaining estimates of the proportion of pregnant females in a population non- destructively. Therefore, there is a rationale for the development of a reliable, non-lethal pregnancy test for sharks that would allow researchers to estimate the percentage of spawning females in Atlantic populations of several LCS and SCS that have been identified as species of special concern (i.e., great and scalloped hammerhead sharks Sphyrna mokarran and S. lewini, bonnethead S. tiburo, Atlantic sharpnose Rhizoprionodon terranovae, sandbar shark Carcharhinus plumbeus, blacktip shark C. limbatus, blacknose shark C. acronotus, and finetooth shark C. isodon). Therefore, the purpose of this study is to develop a reliable, non-lethal pregnancy test for commercially and recreationally exploited sharks belonging to the families Carcharhinidae and Sphyrnidae. This objective will be fulfilled by developing antibody probes against protein “biomarkers” of pregnancy from carcharhinids and sphyrnids, which will be identified using two- dimensional difference in gel electrophoresis (2D-DIGE) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis of plasma from pregnant and non-pregnant sharks from multiple shark species. We will then use these markers to screen the pregnancy status of LCS and SCS captured in both fishery-independent and fishery-dependent sampling efforts conducted throughout the southeast U.S. coast. This will allow us to validate the broad use of this approach and begin to obtain information on the reproductive periodicity of species of concern in Atlantic waters. Overall, this study is expected to result in the development of a new non-lethal tool for estimating the percentage of spawning females of commercially and recreationally important shark populations in U.S. Atlantic waters. This information is critical for refining estimates of long-term biological productivity of the LCS and SCS complexes. PI: Dr. James Gelsleichter (NA16NMF4540082) |

| Mote Marine Laboratory | Title: Bringing large sample sizes to the study of post-release mortality in highly migratory species - Synopsis: The proposed work is a continuation and expansion of a CRP-funded project that is proving highly successful and efficient in documenting the post-release mortality and behavior of large coastal sharks caught in the Florida commercial shark fishery. The study integrates conventional and novel techniques that are revolutionizing the study of post-release mortality in coastal species in order to fulfill the following objectives: 1. Document the post-release behavior and mortality of large coastal sharks caught in a commercial longline fishery using shark-borne acceleration data loggers (ADLs), with a focus on dusky and hammerhead sharks. 2. Examine relationships of post-release behavior and mortality to blood biochemistry (e.g. pH, pCO2, lactate, and electrolytes) collected at the time of capture. 3. Examine relationships of post-release behavior and blood biochemistry with fish size, hook time, reflex responses and animal release condition. 4. Build a species-specific post-release survival index based on at-vessel data. The uniquely designed accelerometer/VHF tag package that the lead PI has developed for this work not only provides more detailed and definitive information on animal outcomes than conventional satellite tagging methods, but can do so for 1/7th of the cost. Removing the limitation of high tag costs allows us to obtain higher sample sizes than past studies, and improves our ability to draw significant correlations between blood stress parameters and animal outcomes. To do this, we have assembled a team that combines highly experienced experts in the fields of shark fisheries and post-release mortality with younger scientists who work on the leading edge of blood stress physiology and high-resolution data-logging tag development. We are on pace to achieve an unprecedented sample size of over 100 animals for blacktip, tiger, and sandbar sharks with our current, ongoing work, and we now propose to shift our sampling locations and strategy to target species of concern that are thought to be highly vulnerable to capture stress: dusky sharks (Carcharhinus obscurus) and hammerhead sharks (Sphyrna mokarran, S. lewini).We believe that the proven success and cost-effectiveness of this tagging method, combined with $20K of equipment already in hand from our previous work, make the proposed project an extremely strong investment towards answering a question that NOAA/NMFS scientists have deemed crucial for proper management of large coastal sharks.

| Florida State University | Title: Post-release survivorship, life-history traits and stock characteristics of scalloped and Carolina hammerhead sharks from U.S. Atlantic waters - Synopsis: The scalloped hammerhead (Sphyrna lewini) is a large, coastal to semi-oceanic shark species common to waters of the U.S. east coast and is regularly taken in commercial and recreational fisheries in this region. High rates of hooking mortality and low rates of population growth are believed to have caused severe declines in the U.S. Atlantic population of this species. Recent studies on scalloped hammerheads in the western North Atlantic Ocean have suggested that these populations have been reduced by over 80% of their virgin, unfished stock size, prompting a critical need for careful management based on reliable life history and fishery data. However, certain types of information required for improved management of these populations remain in need. This includes: 1) information on post-release survivorship in longline fisheries, which would allow fishery managers to estimate discard mortality rates as well as evaluate the efficacy of reduced soak times on reducing bycatch mortality; and 2) region-specific data on the reproductive biology of S. lewini, which is needed for accurately estimating rates of population growth for use in demographic models. It is also important to obtain: 3) information on the contribution that the Carolina hammerhead (S. gilberti), a formerly cryptic and now recently named species that are visually indistinguishable from S. lewini, makes to overall “scalloped hammerhead” populations in the western North Atlantic Ocean as its co-occurrence with S. lewini, due to partial geographic overlap in this region, may complicate accurate estimation of stock status. To make this information available in time for upcoming stock assessments, we propose to conduct a multifaceted study on Atlantic scalloped hammerheads in collaboration with commercial fishers from Florida and South Carolina. We will determine rates of post-release survival of scalloped hammerheads caught on commercial longlines through the use of “survivorship” tags, a new version of pop-off archiving satellite tags specifically designed to assess mortality less expensively than traditional satellite tags and relating the results to chemical parameters in the blood that can be indicators of physiological stress. We will obtain region-specific data on reproduction through the use of non-lethal indicators of maturity and reproductive stage (e.g., clasper measurements in males, pregnancy assessments via ultrasound in females, plasma concentrations of gonadal steroid hormones), as well as through use of archived and newly collected data on reproductive tract morphology and age in necropsied individuals. We will also determine the ratio of abundance of S. lewini to S. gilberti in Atlantic scalloped hammerhead populations by conducting next-generation sequencing of reduced-representation DNA libraries of restriction-site associated DNA (RAD), a high-resolution approach for identifying genetic differences among species. Finally, if possible, we will begin to obtain data on reproduction and growth for S. gilberti using non-lethal and/or invasive measures of the reproductive condition and vertebral band analysis, respectively.

| Mote Marine Laboratory | Title: Reducing Bycatch and Optimizing Efficiency in the Gulf of Mexico Fishery, Phase I: Accurately Assessing the Bycatch Problem Using Electronic Monitoring in Cooperative Research - Synopsis: This project responds to a direct request from the U.S. Gulf of Mexico (GOM) commercial fishing industry for assistance with the problem of an increasing bycatch of sharks and other non-target species in the reef fish (grouper/snapper) fishery. Utilizing a pilot system of Electronic Monitoring (EM) already in place, we will work cooperatively and collaboratively with this sector and our NMFS partner to assess the extent and characteristics of this bycatch problem, which affects one of the Gulf’s most important fisheries and HMS under NMFS and state management. Reducing bycatch of sharks is a priority for NMFS and state agencies due to the vulnerability of shark species to overfishing. The project will use EM to accurately identify shark species interacting with GOM reef fish gear (bottom longlines and vertical bandit rigs), characterize their size, sex, spatio-temporal distribution and bycatch disposition, and also assess the extent of other non-target bycatch in this fishery. Use of EM technology to identify and quantify shark bycatch is currently hampered by a species identification problem. PI: Dr. Carole Neidig, Dr. Robert Hueter (NA16NMF4540085) | $198,625 |

| South Carolina Department of Natural Resources | Title: Determining the stock boundary between South Atlantic and Gulf of Mexico managed stocks of Coastal Migratory Pelagic Cobia, Rachycentron canadum, through the use of telemetry and population genetics - Synopsis: Cobia (Rachycentron canadum) is a popular saltwater recreational fishery in the southeastern United States due to the ease of access, brute fighting strength, and excellent culinary qualities. Cobia is federally managed under the Coastal Migratory Pelagic Resources fishery management plan (FMP), however, the benchmark assessment for cobia (SEDAR28) did not occur until 2012. From 1983‐2012, Gulf of Mexico and South Atlantic cobia were managed as one stock, with management authority shared by the Gulf and South Atlantic Fishery Management Councils. Differing life history characteristics, such as growth rate and maximum age, led to Amendment 18 of the FMP which split the management authority between the Gulf and South Atlantic management councils and set the management boundary at the Monroe County line in Florida. Population genetic and tagging data presented at SEDAR 28 confirmed genetic structure separating Gulf and Stocks Atlantic stocks, however, the data rejected the Florida Keys as the biological stock boundary. Tagging data suggested it was likely farther up the east coast between Port St. Lucie, Florida and Hilton Head, South Carolina. As a result, Amendment 20B of the FMP moved the demarcation line for cobia stock management to the Florida/Georgia border. Research recommendations from SEDAR 28 specifically called for increased tagging efforts (acoustic in particular) to improve data on movement and population dynamics. The Florida Acoustic Cooperative Telemetry (FACT) Array is a network of submerged acoustic receivers deployed along the Florida east coast while the Atlantic Cooperative Telemetry (ACT) Array includes coastal arrays in the South Atlantic bight. This existing infrastructure offers a unique collaborative research opportunity to answer a specific management question. Here we propose to identify the geographic location of the biological stock boundary between the Gulf of Mexico and South Atlantic cobia stocks, using population genetics and passive acoustic telemetry. Our research would employ charter boat captains and recreational fishermen to assist with cobia capture and acoustic tag implantation (50 per state) and genetic sample collection. Because cobia are rarely encountered by regular fisheries independent sampling programs (trammel net, long‐line, etc.), there is a strong need for fisheries dependent data collection for this species. This work would leverage the well‐ developed acoustic receiver infrastructure along the Atlantic coast to study coastal movements of tagged cobia and employ population genetic analyses and individual‐based assignment to identify stock‐of‐origin for all sampled individuals. Our project specifically relates to stated program priorities 1.d. projects to develop methods to increase the amount of at‐sea observations including imaging systems and to obtain life history information and 1.e. data collection projects to improve life history information on commercial and recreational finfish and elasmobranch species.
