Responsible Federal Agency: Pacific Islands Regional Office (PIRO) National Marine Fisheries Service (NMFS) National Oceanic & Atmospheric Administration (NOAA) Responsible Official: Michael D. Tosatto Regional Administrator, PIRO 1845 Wasp Blvd., Bldg. 176 Honolulu, HI 96818 Tel (808) 725-5000 Fax (808) 725-5215 Responsible Council: Western Pacific Fishery Management Council 1164 Bishop Street, Suite 1400 Honolulu, HI 96813 Tel (808) 522-8220 Fax (808) 522-8226 Abstract The Western Pacific Fishery Management Council (Council) and National Marine Fisheries Service (NMFS) propose to establish bigeye tuna territorial catch and allocation limits for each U.S. participating territory in the western and central Pacific Ocean, as recommended annually by the Council, for years 2019-2023, pursuant to the Fishery Ecosystem Plan for the Pacific Pelagic Fisheries of the Western Pacific Region (Pelagics FEP). NMFS would authorize each U.S. territory to allocate and transfer bigeye tuna limits to a U.S. longline fishing vessel(s) permitted under the Pelagics FEP and identified in a specified fishing agreement applicable to the territory. Criteria for a specified fishing agreement and the process for attributing longline- caught bigeye tuna made by vessels of the U.S. participating territories and U.S. vessels identified in an approved specified fishing agreement are codified in 50 CFR 665.819. If approved, the catch and allocation limits would be in effect until the end of the relevant fishing year. Draft Environmental Assessment Territorial Bigeye Tuna Catch and Allocation Limits This environmental assessment (EA) considers the following alternatives for catch and allocation limit specifications in detail: • Alternative 1: NMFS would not specify annual territorial bigeye tuna catch or allocation limits (No Action). • Alternative 2: NMFS would specify, for each territory, an annual 2,000 metric ton (t) catch limit and 1,000 t allocation limit (Preferred/Status Quo). • Alternative 3: NMFS would specify, for each territory, an annual 2,000 t catch limit and up to a 2,000 t allocation limit. The alternatives are identical to those analyzed in the EA supporting the 2018 Bigeye Tuna Catch and Allocation Limits for Pelagic Longline Fisheries in the U.S. Pacific Island Territories (NMFS 2018g). The analysis in this EA indicates that none of the three action alternatives for catch and allocation limits and accountability measures are expected to result in adverse effects on the long-term sustainability of bigeye tuna, other non-target species, bycatch species, protected species, or adversely affect marine habitats, or result in large changes to any western Pacific longline fishery in a given year from 2019 through 2023. At its 176th meeting, from March 19-21, 2019, in Honolulu, Hawaii, the Council recommended a 2,000 t bigeye tuna catch limit and 1,000 t allocation limit for fishing year 2019, which is NMFS’ preferred alternative in this EA. The Western Pacific longline fisheries have operated under this preferred alternative since 2014. NMFS’ issuance of any future territorial bigeye tuna catch and allocation limits will be based on Council recommendations, which will in turn be based on the best available scientific information relevant to management objectives. Future proposed catch and allocation limits will be subject to additional review by NMFS and opportunities for public comment.
