NMFS adopts a rule that modifies the Individual Fishing Quota (IFQ) Program for the fixed-gear commercial Pacific halibut fishery and sablefish fishery by revising regulations specific to those fisheries. This action is intended to improve the effectiveness of the Halibut and Sablefish IFQ Program (IFQ Program) and is necessary to promote the objectives of the Magnuson-Stevens Fishery Conservation and Management Act (Magnuson-Stevens Act) and the Northern Pacific Halibut Act of 1982 (Halibut Act) with respect to the IFQ fisheries.
