International Fisheries; Pacific Tuna Fisheries; Fishing Restrictions for Tropical Tuna in the Eastern Pacific Ocean for 2018 to 2020

NMFS proposes regulations under the Tuna Conventions Act to implement provisions included in Resolution C-17-02 (Conservation Measures for Tropical Tunas in the Eastern Pacific Ocean During 2018- 2020), which was adopted at the 92nd Meeting of the Inter-American Tropical Tuna Commission (IATTC or Commission) in July 2017. This proposed rule would implement the C-17-02 management measures for tropical tuna (i.e., bigeye tuna (Thunnus obesus), yellowfin tuna (Thunnus albacares), and skipjack tuna (Katsuwonus pelamis)) for 2018 to 2020 in the eastern Pacific Ocean (EPO). The proposed rule would impose on purse seine vessels of class sizes 4-6 (carrying capacity greater than 182 metric tons (mt)) fishing for tropical tuna in the EPO: A 72-day closure, a 31-day area closure, and a requirement that-- with some exceptions--all tropical tuna be retained and landed. In addition, this proposed rule would revise the restrictions for force majeure, establish a bigeye tuna catch limit of 750 mt for U.S. longline vessels greater than 24 meters (m) in overall length, and regulate the use of fish aggregating devices (FADs). This proposed rule is necessary for the conservation of tropical tuna stocks in the EPO and for the United States to satisfy its obligations as a member of the IATTC.
