NMFS issues regulations to remove limits on the maximum amount of halibut individual fishing quota (IFQ) that may be harvested by a vessel, commonly known as vessel use caps, in IFQ regulatory Areas 4A (Eastern Aleutian Islands), 4B (Central and Western Aleutian Islands), 4C (Central Bering Sea), and 4D (Eastern Bering Sea). This action is needed to provide additional flexibility to IFQ participants in 2022 to ensure allocations of halibut IFQ can be harvested by the limited number of vessels operating in these areas. This action is within the authority of the Secretary of Commerce to establish additional regulations governing the taking of halibut that are in addition to, and not in conflict with, those adopted by the International Pacific Halibut Commission (IPHC). This action is intended to promote the goals and objectives of the IFQ Program, the Northern Pacific Halibut Act of 1982 (Halibut Act), and other applicable laws.
