      West Coast Groundfish Bottom Trawl Survey Data Dataset Description This data set contains information on date, time, vessel, trawl identification (i.e. unique number), trawl performance, . Fish benthic trawls were completed by the National Marine Fisheries Service Groundfish Survey Program (NMFS GSP). Data from fishery independent trawls ranging from m in depth were collected June-November in , , , , and Fish that were not present in at least 5% of the trawls .

        In their announcement, MSC noted that the West Coast Groundfish IFQ Trawl Fishery is “the most diverse, complex fishery ever to enter assessment against the MSC standard anywhere in the world.” The fishery includes west coast favorites like sablefish and petrale sole, along with first-of-their-kind species in the MSC program like lingcod, thornyheads, and several varieties of Pacific rockfish. DISCUSSION PAPER Trawl sweep modifications for the Bering Sea flatfish fishery Conservation Engineering (RACE) Division have been working with the fishing industry, notably John Gauvin and the Head and Gut Workgroup, to modify groundfish trawls .

Differences in data collection by local management agencies limit regional comparisons. Groundfish trawls dominate the Alaska, Pacific coast. In Atlantic Canada, many different groundfish species are incidentally caught in bottom trawls.

These include halibut, haddock, cod, hake, redfish and pollock, among others. Each year, about 60 to 70 trawlers under 65 feet (20 metres) actively participate in the groundfish.
