The 2018 Eastern Bering Sea Continental Shelf and Northern Bering Sea Trawl Surveys: Results for Commercial Crab Species

The eastern Bering Sea bottom trawl survey has been conducted annually since 1975 by the Resource Assessment and Conservation Engineering Division of the Alaska Fisheries Science Center, National Marine Fisheries Service. The purpose of this survey is to collect data on the distribution and abundance of crab, groundfish, and other benthic resources in the eastern Bering Sea. These data are used to estimate population abundance and biomass for the management of commercially important species. This document includes the time series of results from 1975 to the present. In 2018, 375 total stations were sampled on the eastern Bering Sea shelf from 3 June to 31 July.
