The National Marine Fisheries Service (NMFS), on behalf of the Secretary of Commerce, is responsible for managing Atlantic highly migratory species (HMS) 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. NMFS is developing a rule that would consider implementing area closures for HMS fisheries that complement area closures for fisheries managed under non-HMS fishery management plans. Some of these closures, for example the ones for bottom longline gear, would be wholly new closures in HMS fisheries. Other area closures, such as those related to the Madison-Swanson and Steamboat Lumps closed areas, could include changes and possibly additional restrictions to existing HMS area closures. The Regional Fishery Management Councils requested that NMFS implement these complementary measures in HMS fisheries to simplify enforcement of protections for bottom habitat and reef species.
