The U.S. National Marine Fisheries Service has issued new five-year affirmative findings for the Governments of Ecuador, Guatemala, Mexico, and Spain under the Marine Mammal Protection Act. These new five-year affirmative findings will allow yellowfin tuna and yellowfin tuna products harvested in the eastern tropical Pacific Ocean in compliance with the International Dolphin Conservation Program by The Nations’ flagged purse seine vessels or purse seine vessels operating under The Nations’ jurisdiction to be imported into the United States. The new five-year affirmative findings were based on reviews of documentary evidence submitted by the Governments of The Nations and obtained from the InterAmerican Tropical Tuna Commission. These new five-year affirmative findings are effective for the five-year period of April 1, 2015, through March 31, 2020.
