The experimental trawl was equipped with a small cookie sweep while the standardized trawl has a larger rock-hopper sweep. This work was done on a commercial twin-trawler that was capable of towing both nets side-by-side simultaneously. This work was undertaken in Southern New England waters in depths (30-50 meters) assumed to have high flounder and skate densities. Ninety two valid paired tows were accomplished. Efficiency and size selectivity for the two configurations were compared. completed Foley, Catherine 166 Water Street Woods Hole MA 02543 catherine.foley@noaa.gov pointOfContact Foley, Catherine 166 Water Street Woods Hole MA 02543 catherine.foley@noaa.gov custodian asNeeded cookie sweep cooperative research rock hopper sweep size selectivity sweep efficiency twin trawl theme 2008 2009 temporal Northwest Atlantic Southern New England place benthic demersal pelagic stratum DOC/NOAA/NMFS/NEFSC > Northeast Fisheries Science Center, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
