ISSF Board Repeals Conservation Measure on Indian Ocean Yellowfin Tuna
The Board of Directors of ISSF voted to repeal ISSF Conservation Measure 1.3 – IOTC Yellowfin Tuna Rebuilding following a review of updated scientific advice on the status of Indian Ocean yellowfin tuna.“ISSF adopted CM 1.3 to support stock rebuilding at a time when scientific advice clearly indicated urgent action was needed and wasn’t being taken by the IOTC,” said Susan Jackson, President of ISSF. “While stock recovery is driven by multiple factors, the actions taken by ISSF participating companies to follow the scientific advice at the time demonstrates how industry can contribute constructively when management processes are lacking.”

97% of Global Tuna Catch Comes from Stocks at Healthy Abundance Levels; Nearly 100% Not Experiencing Overfishing
Record Sustainability Milestone Reflects Continued Progress Through Science-Based Fisheries Management
Ninety-seven percent of the world’s total commercial tuna catch now comes from stocks at “healthy” abundance levels, according to the January 2026 ISSF Status of the Stocks report. This is a ten-percentage-point increase from the previous March 2025 report. At the same time, nearly 100% of the global tuna catch comes from stocks not experiencing overfishing, indicating that tuna fisheries are not only biologically healthy but also being harvested at sustainable levels. Both figures represent the highest levels ever reported by ISSF.
