Description:In 2022, the Resource Assessment and Conservation Engineering (RACE) Division of the National Marine Fisheries Service’s (NMFS) Alaska Fisheries Science Center (AFSC) conducted the 40th eastern Bering Sea (EBS) Crab/Groundfish Bottom Trawl Survey and 5th northern Bering Sea (NBS) Crab/Groundfish Bottom Trawl Survey. The survey covered the eastern Bering Sea continental shelf (bottom depths between approximately 20 and 200 m) from the Alaska mainland coast to the U.S.-Russia Maritime Boundary between the Alaska Peninsula and the Bering Strait. Survey sampling was conducted using two chartered commercial stern trawlers, the 43.9-m FV Alaska Knight and 37.8-m FV Vesteraalen. Demersal populations of fishes and invertebrates were sampled by trawling for 30 minutes at stations arranged on a systematic grid, which consisted of 376 total stations in the EBS and 144 total stations in the NBS. At each station, species composition, sex, length-frequency composition, and age structure samples were collected from ecologically and commercially important fish species.
