Securing the Future of Eastern Pacific Tuna: ISSF’s 2025 Priorities for the IATTC

The Eastern Pacific Ocean (EPO) is home to some of the world’s most productive tuna fisheries, supplying a vital source of protein to millions of people while sustaining coastal economies across the Americas and beyond. The Inter-American Tropical Tuna Commission (IATTC) plays a central role in ensuring these fisheries are managed sustainably. As delegates prepare for the IATTC’s 2025 Annual Meeting in September, ISSF is urging action on a set of science-driven priorities to safeguard the long-term health of tuna stocks and the ecosystems that support them.

The 2025 ISSF position statement emphasizes three interconnected areas: adopting effective harvest strategies; strengthening electronic monitoring (EM) and increasing observer coverage; and implementing science-based tuna conservation measures. Together, these steps can help secure the future of the region’s fisheries, supporting healthy marine ecosystems and responsible resource stewardship.
