2014 Alaska Sablefish Longline Survey Report

On August 28, 2014, the Alaska Fisheries Science Center (AFSC) completed the thirty-sixth annual longline survey of Alaska sablefish (Anoplopoma fimbria) and other groundfish resources of the upper continental slope (Figure 1). This survey was designed to continue the time series (1979-94) of the Gulf of Alaska portion of the Japan-U.S. cooperative longline survey that was discontinued after 1994. The National Marine Fisheries Service (NMFS) has surveyed the Gulf of Alaska annually since 1987, the eastern Aleutian Islands biennially since 1996, and the eastern Bering Sea biennially since 1997. The Gulf of Alaska and eastern Aleutian Islands were sampled in 2014.

Alaska Sablefish Tag Program, 1972 - 2012

The National Marine Fisheries Service (NMFS) Alaska Sablefish Tag Program has released over 360,000 tagged sablefish in Alaska waters since 1972 and over 33,500 of those fish have been recovered by members of the fishing industry. Data from the releases and recoveries are maintained in the Sablefish Tag Database. These data have been used to examine movement patterns, evaluate areal apportionment strategies of annual catch quota, validate ageing methods, and examine growth. The following article summarizes release and recovery data within the tag database and describes the results of studies utilizing these tag data by NMFS and others on sablefish age, growth, and migration.
