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 North Atlantic albacore tuna (northern albacore) annual baseline quota for 2025 with available underharvest of the 2024 adjusted U.S. northern albacore quota; adjust the North and South Atlantic swordfish annual baseline quotas for 2025 with available underharvest of the 2024 adjusted U.S. swordfish quotas and international quota transfers; and augment the 2025 Atlantic bluefin tuna Reserve category quota with available underharvest of the 2024 adjusted U.S. bluefin tuna quota. Existing regulations provide for such adjustments annually in order to extend fishing opportunity, and NMFS takes such action each year when complete catch information for the prior year is available. This rulemaking would also consider changes to allow for the modification of North Atlantic swordfish and bluefin tuna baseline quotas consistent with the management procedures for these species as approved by ICCAT. Regulatory changes in this action would affect the northern albacore fishery in the Atlantic Ocean. Temporary quota adjustments in this action would affect the bluefin tuna, northern albacore, and swordfish fisheries for 2025 in the Atlantic Ocean. Implementation of the management procedures 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).
