Stability in Stock Status Underscores Importance of Rigorous Scientific Monitoring to Support Decision-making
Of the total commercial tuna catch worldwide, 85% comes from stocks at “healthy” levels of abundance, according to the newest ISSF Status of the Stocks report. Overfished stocks accounted for 11% of the total catch, and 4% of the catch came from stocks at an intermediate level of abundance.
No individual stock statuses have changed since the March 2023 Status of the Stocks report. The updated report incorporates recent stock-assessment results for Western Pacific bigeye, Western Pacific yellowfin, North Pacific albacore, North Atlantic albacore, and Southern bluefin, none of which has changed. The lack of substantial changes in stock status between report periods highlights the value of continuous scientific assessments to inform stock-management decisions.
Interactive Stock Status Tool and Catch Tool
Our interactive tool allows you to visualize current and historical data from ISSF’s Status of the Stocks report, which compiles scientific assessments of 23 commercial tuna stocks worldwide.
The tool has three tabs — one for visualizing tuna stock health since 2011, another for visualizing the current tuna catch by fishing method, and a third with catch trends by fishing method since 1950.
There is not one individual fish called “tuna” – there are more than a dozen species of tuna worldwide. We highlight the major commercial tuna species on our website, reviewing characteristics, geographic locations, and more.
