These files contain rasterized interpolated biomass distributions for fish and invertebrate species caught in NOAA Fisheries fishery-independent bottom trawl surveys. The distribution maps were produced for the Distribution Mapping and Analysis Portal (DisMAP) project. The distributions were generated from catch-per-unit-effort data from the fisheries bottom trawl surveys. This data set covers 7 regions of the United States: Northeast, Southeast, Gulf of Mexico, West Coast, Eastern Bering Sea, Aleutian Islands, and Gulf of Alaska.
