This final rule announces the approval of the Pacific Halibut Catch Sharing Plan (Plan) and codified regulations for the International Pacific Halibut Commission's (IPHC or Commission) regulatory Area 2A off Washington, Oregon, and California (Area 2A). In addition, NMFS announces the implementation of the portions of the Plan and management measures that are not regulated through the IPHC, including the sport fishery allocations and management measures for Area 2A. The intent of this final rule is to conserve Pacific halibut, provide angler opportunity where available, and minimize bycatch of overfished groundfish species.
