NMFS issues a final rule to implement a groundfish retention standard (GRS) program in the Bering Sea and Aleutian Island management area (BSAI) for trawl catcher/processor vessels (C/Ps) that are 125 ft (38.1 m) length overall (LOA) or greater and that are not listed American Fisheries Act (AFA) catcher/processors referred to throughout this rule as non-AFA trawl C/Ps. This action is necessary to reduce bycatch and improve utilization of groundfish harvested by these non- AFA trawl C/Ps. This action is intended to promote the management objectives of the Improved Retention/Improved Utilization (IRIU) program, the Fishery Management Plan for Groundfish of the Bering Sea and Aleutian Islands Management Area (FMP), and the Magnuson-Stevens Fishery Conservation and Management Act (Magnuson-Stevens Act).
