• Description:
  In 2021, the Alaska Fisheries Science Center completed the 44th annual longline survey in the eastern Bering Sea and the Gulf of Alaska. The survey sampled demersal waters of the upper continental slope and provided stock assessment information on sablefish (Anoplopoma fimbria) and several other groundfish species. The primary objectives of the survey were to determine 1) relative abundance of groundfish species through a standardized longline survey, 2) age composition of sablefish through otolith collection, and 3) movement patterns of selected groundfish species through a tag and recapture program. This processed report provides a summary of raw data and operations details from the 2021 longline survey.
