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 and consistent with the Atlantic Tunas Convention Act (ATCA), the implementing statute for binding recommendations of the International Commission for the Conservation of Atlantic Tunas. NMFS is considering changes to regulations regarding demersal and pelagic indicator species in the HMS pelagic and bottom longline fisheries in order to increase flexibility and remove inefficiencies while still achieving fishery management and conservation goals. Currently, to be considered a pelagic longline vessel when fishing in a bottom longline closed area, no more than five percent (by weight) of the species possessed or landed may be demersal indicator species, as measured relative to the total weight of all pelagic and demersal indicator species. Likewise, to be considered a bottom longline vessel when fishing in a pelagic longline closed area, no more than five percent (by weight) of the species possessed or landed may be pelagic indicator species, as measured relative to the total weight of all pelagic and demersal indicator species. While these management measures helped achieve fishery management and conservation goals in the past, the measures may no longer be necessary due to changes in fishery monitoring methods and fishing techniques. This action is being taken pursuant to the rulemaking authority under section 304(g) of the Magnuson-Stevens Fishery Conservation and Management Act.
