NOAA Fisheries has been tagging and releasing sablefish in Alaska waters since 1972. In that time, approximately 360,000 tags have been released and over 34,000 have been recovered. Tagging effort in Alaska has been centered in three main areas: 1) adult sablefish in offshore waters of the Gulf of Alaska, Bering Sea, and the Aleutian Islands; 2) adult sablefish in the inside waters of Chatham and Clarence Straits; and 3) juvenile sablefish in southeast Alaska.
