MARMAP Chevron Trap Survey 1990-2009Entry ID: MARMAP_Chevron
Abstract: Abundance and biomass of fish species collected during the day from 1988 to 2000 off the coast of the southeastern United States (Cape Fear, NC to Cape Canaveral, FL). Chevron traps were set on live-bottom reef areas on the continental shelf and upper slope. Chevron traps were arrowhead shaped (maximum dimensions of 1.5 m x 1.7 m x 0.6 m.; 0.91 m3 volume) and constructed of 35 mm x 35 mm square mesh plastic-coated wire. Chevron traps had one entrance funnel (“horseneck”), and one release panel to remove the catch. Each trap was soaked between 90 and 120 minutes.
Purpose: For thirty years, the Marine Resources Research Institute (MRRI) at the South Carolina Department of Natural Resources (SCDNR), through the Marine Resources Monitoring, Assessment and Prediction (MARMAP) program, has conducted fisheries-independent research on groundfish, reef fish, ichthyoplankton, and coastal pelagic fishes within the region between Cape Lookout, North Carolina, and Ft Pierce, ... ... 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; ichthyoplankton surveys; location and mapping of reef habitat; sampling of reefs throughout the SAB; life history and population studies of priority species; tagging studies of commercially 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 development of an historical base for future comparisons of long-term trends.
Annual MARMAP cruises to assess relative abundance of reef fishes in the sponge-coral and shelf edge (live bottom) habitats of the South Atlantic Bight (SAB) have been conducted since 1978. MARMAP currently samples natural live bottom habitat from Cape Lookout, NC to the Ft. Pierce area, FL. The current main MARMAP objectives are to:
(1) Sample reef fishes in the snapper-grouper complex at using a variety of gears in live bottom, rocky outcrop, high relief, and mud bottom habitats,
(2) Collect detailed data for time series description of species for annual composition and relative abundance,
(3) Obtain population characteristics on fish species of interest through life history information analysis, including age and growth, sex ratio, size and age of sexual maturation and transition, spawning season, fecundity, and diet. Priorities are dictated by the SEDAR schedule and other management considerations,
(4) Collect hydrographic data (e.g. depth, temperature, salinity, etc.) for comparison to fish abundance and composition indices,
(5) Collect DNA samples from selected fish species for stock identification,
(6) Expand sampling area in North Carolina and south Florida as well as reconnoiter new live bottom areas with underwater video (UWTV) to add to the MARMAP site database.

Quality The data have been in use by the agency and other agencies since its inception. The database has undergone rigorous quality checks. Used Differential GPS. Data was truncated to 2nd decimal point (about 1500 meters) with respect to location due to confidentiality.

Users must recognize that the analysis and interpretation of data requires background knowledge and expertise about marine biodiversity (including ecosystems and taxonomy). Users should be aware of possible errors in the use of species names, geo-referencing, data handing and mapping. They should crosscheck their results for possible errors, and qualify their interpretation of any results accordingly. Appropriate caution is thus necessary in the interpretation of results derived from OBIS-USA.
