‘Historic moment’: Nations act to save Pacific bluefin tuna

Today in Busan, South Korea, Pacific nations came together and agreed, for the first time, to recover the population of Pacific bluefin tuna to a sustainable level.

“This is a historic moment for this remarkable species, which is so important to the ocean ecosystem and to coastal communities around the Pacific Rim,” said Margaret Spring, Chief Conservation Officer for the Monterey Bay Aquarium.

At the annual meeting of the Northern Committee of the Western and Central Pacific Fisheries Commission—the body responsible for managing tunas and other highly migratory species across the western Pacific Ocean—international delegates discussed ways to recover the population of Pacific bluefin tuna after years of decline. Ultimately, they took a major step forward by agreeing to recover the population to a sustainable level and establishing a long-term management plan.

Tuna Commission fails to adopt new conservation measures for highly depleted Pacific bluefin tuna

Statement of Margaret Spring, Vice President of Conservation and Science and Chief Conservation Officer, Monterey Bay Aquarium

“The Monterey Bay Aquarium is disappointed that nations at the 89th meeting of the Inter-American Tropical Tuna Commission were unable to reach agreement on any new measures to conserve Pacific bluefin tuna populations. Pacific bluefin tuna are key top predators in the ocean, but the population’s breeding stock has been depleted to approximately 4% of historic levels. As the population continues to decline, we need all Pacific nations to collaborate and commit to a science-based, long-term recovery plan that will result in a healthy, sustainable Pacific bluefin population.

“We applaud the United States’ leadership in advancing a proposal at last week’s meeting to support new scientific analyses and collaboration across international science advisory bodies that could improve future conservation and management decisions. We strongly support the United States’ effort to include a science-based recovery target, known as maximum sustainable yield, as an indication of what measures are needed to ensure the long-term conservation and sustainable use of the species.

“Despite significant support from most Member nations, the Commission could not reach a consensus on the U.S. scientific analysis proposal, and unfortunately did not adopt any new measures.

“Now is the time for all nations fishing in the region to think beyond purely domestic concerns and commit to a Pacific-wide plan to reverse the decline of Pacific bluefin tuna in a meaningful, responsible and cooperative manner. This must start with a commitment to strictly adhere to scientific advice in establishing rebuilding targets. And it must include serious consideration of other conservation measures, such as protection for bluefin spawning areas.

“The next opportunity for action comes when the Northern Committee of the Western and Central Pacific Fisheries Commission meets in Japan at the end of August. We urge all parties to pledge their support for new international research investments, including electronic and emerging techniques for tagging and tracking bluefin tuna populations across the Pacific. This commitment is essential to strengthen conservation measures, and to advance a science-based, long-term rebuilding plan that will recover the species to sustainable levels.”
