87.7% of Global Tuna Catch Continues to Come from Stocks at Healthy Levels; 9.6% Require Stronger Management

Of the total commercial tuna catch worldwide, 87.7% of the global catch continues to be sourced from stocks at “healthy” levels of abundance, according to the newest International Seafood Sustainability Foundation (ISSF) Status of the Stocks report. In addition, 9.6% of the total tuna catch came from overfished stocks, and 2.7% came from stocks at an intermediate level of abundance.

Several tuna stocks worldwide are considered overfished and/or subject to overfishing:

  • The Indian Ocean yellowfin and Pacific bluefin tuna stocks continue to be overfished and subject to overfishing.
  • Atlantic Ocean bigeye status remains overfished and subject to overfishing, although the results of the most recent RFMO Science Committee meeting were not available at the time of writing and will be reflected in the next report update. 
  • Indian Ocean albacore and bigeye continue to be subject to overfishing.
  • All skipjack and most albacore stocks remain healthy.

ISSF publishes its signature Status of the Stocks report twice each year using the most current scientific data on 23 major commercial tuna stocks.
