Southeast Region Headboat Survey-Dockside validation data
The Headboat Survey provides many products to fishery managers through its data collection programs. Annual landings estimates, by species, area and month are provided for all species encountered in the survey. These fishery dependent estimates were used by stock assessment scientists in all SEDARs in both the south Atlantic and Gulf of Mexico in all stock assessments both before and after the SEDAR process began

Southeast Region Headboat Survey-Landings Estimates
공공데이터포털
A correction factor is calculated by month and vessel to adjust for misreporting as described above. These correction factors are applied to the reported landings by species-vessel-month combinations to generate total estimated numbers of fish landed. These numbers are then multiplied by mean weights of fish calculated from the bioprofile data by species-area-month combinations to generate a total weight of fish landed for each species-vessel-month combination. Landings estimates are provided by species, area and month.

Southeast Region Headboat Survey-Catch Records
공공데이터포털
The Southeast Region Headboat Survey (SRHS), administered by National Marine Fisheries Service (NMFS) Southeast Fisheries Science Center (SEFSC) personnel based at the Beaufort, NC NOAA Laboratory, has operated along the southeast U.S. Atlantic coast since 1972 and along the U.S. Gulf of Mexico coast since 1986. The survey is the longest continuous time series of recreational fisheries data from federal waters on the U.S. east coast, and second longest on the U.S. Gulf of Mexico coast (behind the NMFS Marine Recreational Fisheries Statistics Survey / Marine Recreational Information Program, initiated along the Gulf Coast in 1981). The Headboat Survey provides many products to fishery managers through its data collection programs. Annual landings estimates, by species, area and month are provided for all species encountered in the survey. These fishery dependent estimates were used by stock assessment scientists in all SEDARs in both the south Atlantic and Gulf of Mexico in all stock assessments both before and after the SEDAR process began.The logbook data is used to derive a long-term fishery dependent index of abundance used by stock assessment scientists in assessing long-term health of the populations.
Large Pelagic Logbook Trip Survey (Vessels)
공공데이터포털
This data set contains catch and effort for fishing trips that are taken by vessels with a Federal permit issued for the swordfish and sharks under the Highly Migratory Species (HMS) fishery management plan. Fishermen that own vessels with permits in these fisheries are required to complete a vessel logbook for every trip in which any species in the Highly Migratory Species fishery management plans are caught and landed. Fishermen are not required to report fishing trips in which other than these species are caught. However, fishermen are required to submit a no-fishing report if they did not fish for or catch any HMS species during a calendar month. In 1986, the Southeast Fisheries Science Center (SEFSC) initiated a logbook program for vessels that held a federal vessel permit to fish for swordfish in the Atlantic Ocean and Gulf of Mexico. In 1993, a similar program was initiated for vessels with a federal permit to fish for sharks that are included in the HMS fishery management plan. In order to provide sufficient level of detail for fishing effort by the longline vessels, the catch and effort data need to be reported for each longline set. Consequently, a single logbook form was designed for the fishermen to record the catch (numbers of animals caught) and effort, which includes data on the length of the longline, the number of hooks and the duration of the set. To reduce the number of times that fishermen need to record certain pieces of information, e.g., location of unloading, duration of trip, number of crew, a trip summary form was designed in 1999 that includes the trip-related information that is the same for every set. This redesign of the logbook form resulted in two forms, the trip summary and the set forms. Only one trip summary needs to be completed for each trip, but a separate set form needs to be completed for each longline set made during the trip. At the same time, additional questions were added to the trip summary form to collect information on the expenses that the vessels incurred during the trip. Initially, this information was voluntary and the fishermen did not have to provide the cost data whereas the catch and effort data are mandatory and the vessels permit will not be renewed if logbooks are not received for every trip where swordfish and/or sharks are caught and landed.

Southeast Region Headboat Survey-Bioprofile
공공데이터포털
Dockside biological data collection is primarily used to obtain a representative sample for length and weight by species. The lengths are used in length frequency graphs and the weights are used to calculate mean weights to estimate total landings in weight. In addition, other biological samples may be taken e.g., otoliths, stomachs, spines, or gonads to support studies of age and growth, diet or reproduction.
Water Column Profile Data
공공데이터포털
The Southeast Fisheries Science Center Mississippi Laboratories conducts standardized fisheries independent resource surveys in the Gulf of Mexico, South Atlantic, and U.S. Caribbean to provide abundance and distribution information to support regional and international stock assessments. Environmental profiles are acquired during all surveys and are averaged into one meter depth bins. The data are acquired with Sea-Bird SBE25 and SBE9 profilers equipped with water temperature, conductivity, dissolved oxygen, beam transmittance, and fluorescence sensors. These are raw data that are unprocessed.
SEAMAP Reef Fish Survey (1992 - 1997; and 2001 - 2015)
공공데이터포털
The Southeast Fisheries Science Center Mississippi Laboratories conducts standardized fisheries independent resource surveys in the Gulf of Mexico, South Atlantic, and U.S. Caribbean to provide abundance and distribution information to support regional and international stock assessments. The reef fish survey is conducted primarily on the outer continental shelf of the Gulf of Mexico along topographic features (e.g. reefs, banks and ledges) between Brownsville, TX to the Dry Tortugas, FL. A two-stage sampling design is used with the first stage or primary sampling units being blocks 10 minutes of latitude by 10 minutes of longitude and the second stage being randomly selected sites within the blocks. The first-stage units are selected by stratified random sampling, with stratum boundaries defined by geographic region (4 regions: South Florida, Northeast Gulf, Louisiana-Texas Shelf, and South Texas), and by reef habitat area (Blocks < 20 km² reef, Blocks > 20 km² reef). Sampling is conducted using a video camera array, vertical line gear and chevron traps with approximately 400 video cameras, 400 vertical line and 100 traps conducted. The camera array consists of four housings positioned orthogonally and center mounted at a height of 51 cm above the bottom of the array. Each housing contains a pair of black-and-white Videre stereo cameras along with a color mpeg camera. Sampling of reef sites with video cameras occurs only during daylight hours, with the first gear deployment one hour after sunrise and the last gear retrieval one hour prior to sunset. Video arrays soak for 35 minutes. At sites selected for fish sampling, a chevron (or arrow) fish trap or vertical line is used to capture fish for biological samples. The chevron fish trap is constructed with 1.5-inch vinyl-clad mesh. In its greatest dimensions, the trap is 1.76 m in length, 1.52 m in width and 0.61 m in depth. A 0.4 m by 0.29 m blow out panel is placed on one side and kept closed using 7-day magnesium releases. The fish trap soaks for one hour and is baited with squid. The vertical line consists of a mainline with 10 gangions. One 8/0, 11/0 or 15/0 circle hook is attached to each gangion and baited with mackerel (Scomber scombrus). The mainline is soaked for five minutes. Most of the animals captured are measured, weighed, tagged and then released. Those individuals which are moribund or have expired are retained to collect biological data pertaining to the life history of these fishes. Habitat mapping is conducted using the SIMRAD ME70 multibeam echosounder. At each site hydrological data is collected using Conductivity Temperature Depth sensor (CTD).
