NOAA technical memorandum NMFS AFSC 480 ... : In 2023, the Alaska Fisheries Science Center completed the 46th annual longline survey in the eastern Bering Sea and Gulf of Alaska. The survey sampled demersal waters of the upper continental slope and shelf and provided stock assessment information related to 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 report provides a summary of raw data and details of operations from the 2023 longline survey as well as trends observed on the survey over the last 20 years. ...
