NMFS hereby issues regulations under the Tuna Conventions Act of 1950 (Act), as amended, for the U.S. purse seine fishery operating in the eastern Pacific Ocean (EPO) to make U.S. regulations more consistent with the Inter-American Tropical Tuna Commission (IATTC) Resolution on the Capacity of the Tuna Fleet Operating in the Eastern Pacific Ocean. These revisions will ensure that the United States satisfies its obligations under the Tuna Conventions Act while allowing controlled operational flexibility for the U.S. industry consistent with the IATTC management framework.
