Document: ISSF 2024-02: Status of the World Fisheries for Tuna. March 2024*


ISSF 2024-02: Status of the World Fisheries for Tuna. March 2024 summarizes and rates the status and management of 23 major commercial tuna stocks, based on the most recent scientific assessments as well as management measures adopted by the RFMOs.

Known as ISSF’s “Status of the Stocks” report, it uses a consistent methodology focused on three factors: Abundance, Exploitation/Management, and Environmental Impact (bycatch). It does not replace the more detailed information available directly from the RFMOs. But it does serve as a single source in which uniform information is presented. It is reviewed by the ISSF Scientific Advisory Committee, which provides advice on its content.

Status of the World Fisheries for Tuna features charts, graphs, and individual stock assessments, which are organized by ocean or by ocean region. The Management section in all stocks is organized into two sections: Harvest Strategy (divided in the different elements of a HS) and Management measures.

Relative ratings for bycatch impacts by the different fishing methods, which previously were included in the “Status of the Stocks” report, now appear in a separate report, “ISSF 2024-03: Tuna Fisheries’ Impacts on Non-Tuna Species and Other Environmental Aspects: 2024 Summary.”

Related infographics for this report are available: Distribution of Stocks of Major Commercial Tunas by Catch (2011-March 2024) and Distribution of Stocks of Major Commercial Tunas (2011-March 2024).
