AFSC Groundfish and Crab Assessment Program Bottom Trawl Surveys

Survey data also available through API.

Data Caveats

The Resource Assessment and Conservation Engineering (RACE) Division Groundfish Assessment Program (GAP) of the Alaska Fisheries Science Center (AFSC) conducts fisheries-independent bottom trawl surveys to assess the populations of demersal fish and crab stocks of Alaska. Data presented here are presence-only (non-zero) observations from those surveys and therefore CANNOT be aggregated. Please reach out to survey team leads listed in the metadata if clarification is needed.

Selecting all surveys for all years and all species will result in a dataset of approximately 1 million rows and might crash the page. If the entire dataset is required, please use the API or let us know using the Comments page and we'll send the data to you directly.
