Of the total commercial tuna catch worldwide, about 87% comes from stocks at “healthy” levels of abundance, according to the March 2025 ISSF Status of the Stocks report, and that percentage is similar to findings shared in the previous November 2024 report. Overfished stocks account for 2% of the total catch—down eight percentage points from the last report. The percentage of the catch that came from stocks at an intermediate level of abundance is 10%—an eight-percentage-point increase from November 2024 findings.
