This final rule announces the approval of the Catch Sharing Plan (Plan) for halibut fishing in Area 2A (waters off the U.S. West Coast) with modifications recommended by the Pacific Fishery Management Council (Council), and establishes implementing regulations for 2016. These actions are intended to conserve Pacific halibut, provide angler opportunity where available, and minimize bycatch of overfished groundfish species. The sport fishing management measures in this rule are an additional subsection of the regulations for the International Pacific Halibut Commission (IPHC) published on March 16, 2016.
