NMFS issues a final rule to amend regulations implementing the North Pacific Groundfish Observer Program (Observer Program). This action is necessary to improve the operational efficiency of the Observer Program, as well as to improve the catch, bycatch, and biological data collected by observers for conservation and management of the North Pacific groundfish fisheries, including those data collected through scientific research activities. The final rule is intended to promote the goals and objectives of the Fishery Management Plan for Groundfish of the Bering Sea and Aleutian Islands Management Area and the Fishery Management Plan for Groundfish of the Gulf of Alaska.
