Groundfish Assessment Program

Bottom Trawl Surveys

The AFSC Groundfish Assessment Program (GAP) regularly conducts bottom trawl surveys to assess the condition of groundfish and shellfish stocks in Alaskan marine waters.

The surveys range from southeastern Alaska north to the Eastern Bering Sea shelf and slope and to the westernmost Aleutian Islands.

Bottom trawl surveys for groundfish and king and Tanner crabs occur annually in the eastern Bering Sea in cooperation with the AFSC Shellfish Assessment Program. Biennial bottom trawl surveys are conducted in the Aleutian Islands (even years), Gulf of Alaska (odd years), and along the eastern Bering Sea slope (even years).

Beginning in 2017, biennial surveys will occur in the Northern Bering Sea. Bottom trawl surveys are occasionally conducted in the Chukchi and Beaufort Seas. AFSC's Auke Bay Laboratory also conducts longline surveys of sablefish abundance are conducted throughout Alaskan waters.
