Seventy-eight percent of the global tuna catch comes from stocks at healthy levels, an increase of 2 percent since last reported, according to a new publication.

Updated several times per year, Status of the Stocks ranks the 23 stocks of major commercial tunas around the world using a consistent methodology.
The report assigns color ratings (green, yellow or orange) on stock health, alternately noted as “abundance” and “spawning biomass”; fishing mortality; and ecosystem impact.
In 2015, the total major commercial tuna catch was 4.8 million tonnes, a 4% decrease from 2014.
More than half of the total catch (58%) was skipjack tuna, followed by yellowfin (28%), bigeye (8%) and albacore (4%). Bluefin tunas accounted for only 1% of the global catch. These percentages did not change from the February 2017 report. ■
