About Organization

Responsible for the conservation and management of fisheries for tunas and other species taken by tuna-fishing vessels in the eastern Pacific Ocean. Based in La Jolla, CA, IATTC ensures the long-term conservation and sustainable use of tuna stocks through science-based conservation measures, operating the Achotines Laboratory with 48 employees and annual revenue of $12.0 million.

What They Focus On

Sustainable Fisheries

Ensuring long-term conservation of tuna and tuna-like species through science-based management measures balancing commercial harvest with population health.

Climate Impact

Researching ocean warming and acidification effects on tropical tuna populations, particularly vulnerable pre-recruit life stages critical to stock sustainability.

Bycatch Mitigation

Developing and testing technologies reducing unintended marine species capture in tuna fisheries, protecting ecosystem biodiversity in Eastern Pacific waters.
