The Southeast Area Monitoring and Assessment Program – South Atlantic (SEAMAP-SA) is a State/Federal program for collection, management and dissemination of fishery independent data and information in the southeastern United States. The SEAMAP-SA has conducted fishery-independent research on groundfish, reef fish, and coastal pelagic fishes within the region between Cape Hatteras, North Carolina, and Cape Canaveral, Florida. The overall mission of the program has been to determine distribution, relative abundance, and critical habitat of economically and ecologically important fishes of the South Atlantic Bight (SAB), and to relate these features to environmental factors and exploitation activities. Research toward fulfilling these goals has included trawl surveys (from 6-350 m depth), location and mapping of fish habitat, sampling of reefs throughout the SAB, life history and population studies of priority species, tagging studies of important species and special studies directed at specific management problems in the region. Survey work has also provided a monitoring program that has allowed the standardized sampling of fish populations over time, and subsequent development of a historical base for future comparisons of long-term trends. These trend data are used to provide indices of abundance, which are critical for use in stock assessments, and greatly enhance the assessment of abundance of many species within the region. |

<DIV STYLE="text-align:Left;"><DIV><DIV><P STYLE="margin:1 1 1 0;"><SPAN>The South Atlantic Coastal Longline Surveys of Georgia (GA-CLS), South Carolina (SC-CLS), and North Carolina (NC-CLS) are a partnership component of the Southeast Area Monitoring and Assessment Program (SEAMAP) South Atlantic. The primary objectives of the CLSs are to develop a state specific sampling protocol that provides a fisheries independent index of abundance for adult red drum occurring in South Atlantic waters. Additional objectives include 1) conducting fishery-independent longline sampling on adult red drum and coastal shark species to develop information on catch-per-unit-effort (CPUE), 2) collecting biological information (size, sex etc.) and samples (otoliths, gonads, muscle, fin clips etc.) from sub-samples of the red drum catch in order to determine size at age, recruitment to the spawning population, mercury contamination, and genetic composition of the stock, 3) tagging adult red drum and coastal shark species for the collection of migratory and stock identification data, and to 4) disseminate accomplishments and results to the Atlantic State Marine Fisheries Commission (ASMFC) and the National Marine Fisheries Service (NMFS) for inclusion in stock assessments. GA-CLS is a NMFS-sponsored independent survey conducted by the Georgia Department of Natural Resources (GADNR), Coastal Resources Division (CRD). SC-CLS is housed at the Marine Resources Research Institute (MRRI) of the South Carolina Department of Natural Resources (SCDNR). NC-CLS is housed in the North Carolina Division of Marine Fisheries (NCDMF). Surveys for all states began in 2006 - 2007. This group of layers includes 4 datasets: data collection for stations, abundance, tagging, and specimens.</SPAN></P><P STYLE="margin:1 1 1 0;"><SPAN /></P><P STYLE="margin:1 1 1 0;"><SPAN>Station (Event): Includes information such as location, collection date, and abiotic factors. A sampling event is the deployment of any gear, whether it collects biotic or abiotic factors.</SPAN></P><P STYLE="margin:1 1 1 0;"><SPAN /></P><P STYLE="margin:1 1 1 0;"><SPAN>Tagging: For single individuals of a species (SPECIMEN) includes specimen tagging related information (e.g. tag number, tag type, capture and release status, and tagging status).</SPAN></P><P STYLE="margin:1 1 1 0;"><SPAN /></P><P STYLE="margin:1 1 1 0;"><SPAN>Length frequency: For a SPECIE(S), it includes species-specific length frequency information related to the subsample (relative number measured) and the total (total number collected) within each COLLECTION.</SPAN></P><P STYLE="margin:1 1 1 0;"><SPAN /></P><P STYLE="margin:1 1 1 0;"><SPAN>Abundance: For COLLECTION and SPECIE(S) includes information pertaining to the gear used and the sampling effort, including any subsampling regime as well as information related to the total catch (e.g. total abundance and total weight) for any species with available data.</SPAN></P></DIV></DIV></DIV> |
