86% of Global Tuna Catch Continues to Come from Stocks at Healthy Levels, But Some Stocks Remain Overfished

Of the total tuna catch, 86% came from stocks at “healthy” levels — an unchanged share since last reported in October 2018 — according to the March 2019 International Seafood Sustainability Foundation (ISSF)Status of the Stocks report. Skipjack tuna stocks — which remain at healthy levels in all ocean regions — still comprise over one-half of the total catch.

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

Though many of the recent broad indicators of overall global tuna stock health are positive, there are concerns about several stocks.

More than half of the total catch (58%) was skipjack tuna, followed by yellowfin (28%), bigeye (8%) and albacore (5%). Bluefin tunas (3 species) accounted for 1% of the global catch.
