26802 AFSC/RACE/SAP/Armistead: 1975 - 2016 eastern Bering Sea Crab Distribution For Web Data Set Published / External 22354 Shellfish Assessment Program Project In Work 2016-08 The Resource Assessment and Conservation Engineering Division (RACE) of the Alaska Fisheries Science Center (AFSC) conducts bottom trawl surveys to monitor the condition of the demersal fish and crab stocks of Alaska. These data include catch per unit effort for each commercially important crab species at a standard set of stations in the eastern Bering Sea. This is a subset of the main database. Excluded are certain non standard tows and other types of data collected other than species id, species size category, species catch per unit effort (number per square nautical mile), water temperature and depth. The data set was developed to describe the temporal distribution and abundance of commercially important crab species, examine the changes in the species composition of species over time and space, and describe the physical environment of the habitat.

Measurements to nearest millimeter of commercially important eastern Bering Sea crab species were collected at sea. Data was uploaded to an Oracle database and checked for validity (outliers, impossible values). Catch-per-unit-effort (CPUE) estimates in terms of number of crab per square nautical mile were generated for each stock and major size group by sex. These CPUE values were imported into an ArcGIS web map, and published on the Alaska Fisheries Science Center web page.
