Pacific Bluefin Tuna Commercial Harvest Status

On April 21, 2017, NMFS published a final rule (82 FR 18704) regarding domestic implementation of the Inter-American Tropical Tuna Commission (IATTC) Resolution C-16-08 (Measures for the Conservation and Management of Pacific Bluefin Tuna in the Eastern Pacific Ocean). The final rule, in accordance with advice from the Pacific Fishery Management Council, includes annual and trip catch limits that would apply to U.S. commercial vessels that fish for Pacific bluefin tuna in the eastern Pacific Ocean during 2017 and 2018. This rule implements a 600 metric ton (mt) catch limit for both years combined, not to exceed 425 mt in a single year.  In each year, there would be a trip limit of 25 mt until catch is within 50 mt of the catch limit and a 2 mt trip limit when catch is within 50 mt of the catch limit. 

On August 28, 2017, NMFS announced that the 2017 catch limit of 425 mt for U.S. commercial vessels had been exceeded and closed the fishery for the remainder of the 2017 calendar year (82 FR 40720). The catch limit in 2018 will be calculated by subtracting the amount caught in 2017 from 600 mt.

Update: On March 28, 2018, NMFS published a final rule revising trip limits for 2018 only (83 FR 13203). Effective April 27, 2018, U.S. commercial vessels are subject to a 1-mt trip limit for Pacific bluefin tuna—except large-mesh drift gillnet vessels, which are subject to a 2-mt trip limit—for the remainder of 2018. If NMFS anticipates the 2018 catch limit of 114 mt is going to be reached, NMFS will close the fishery for the remainder of 2018.


The Commercial harvest of Pacific bluefin tuna in the IATTC Convention Area is in metric tons (mt).

** The U.S. catch limit is notwithstanding the Commission-wide limit.

*** IATTC Resolution C-12-09 established a Commission-wide limit of 10,000 mt for 2012 and 2013. NMFS implemented the resolution in 2013 when 3,295 mt of the Commission-wide limit remained after the IATTC Director determined that 6,705 mt had been caught by IATTC Members and Cooperating non-members in 2012.
