The National Marine Fisheries Service (NMFS), on behalf of the Secretary of Commerce, is responsible for managing Atlantic highly migratory species pursuant to the Magnuson-Stevens Fishery Conservation and Management Act, 16 U.S.C. 1801 et seq., and consistent with the Atlantic Tunas Convention Act, id. 971 et seq., the implementing statute for binding recommendations of the International Commission for the Conservation of Atlantic Tunas (ICCAT). NMFS is developing a rulemaking that would, on a temporary basis: adjust the annual baseline quotas for North Atlantic albacore tuna (northern albacore), the North and South Atlantic swordfish, and the Atlantic bluefin tuna quota based on harvest levels from 2025. Existing regulations provide for such adjustments annually in order to extend fishing opportunities, and NMFS takes such action each year when complete catch information for the prior year is available. This rulemaking would also consider changes to implement baseline quota modifications as approved by ICCAT. Temporary quota adjustments in this action would affect the bluefin tuna, northern albacore, and swordfish fisheries for 2026 in the Atlantic Ocean. Implementation of the ICCAT measures may similarly affect these fisheries in future years. This action is being taken pursuant to the rulemaking authority under section 304(g)(1) of the Magnuson-Stevens Fishery Conservation and Management Act or 16 U.S.C. 1854(c).
