80.5% of Global Tuna Catch Comes from Stocks at Healthy Levels; 9.2% Require Stronger Management

Of the total commercial tuna catch worldwide, 80.5% is sourced from stocks at “healthy” levels of abundance, according to the newest International Seafood Sustainability Foundation (ISSF) Status of the Stocks report. In addition, 9.2% of the total tuna catch came from overfished stocks, and 10.3% came from stocks at an intermediate level of abundance.

The decrease in the overall percentage of the catch coming from stocks at healthy levels of abundance, from 87.7% in the September 2021 report to 80.5% in the March 2022 update, is mainly attributed to a change in the rating of the Eastern Pacific skipjack stock, which represents about 6% of the global tuna catch.

Biology & Stock Status of Minor Commercial Tunas

Among the 15 species of tunas, eight are called “minor” or “neritic” tunas due to their lower commercial value. Despite this “minor” label, these tunas are exploited commercially and/or caught recreationally and are an important source of nutrition for coastal communities and income for coastal artisanal and subsistence fisheries.

As compared to their commercial counterparts, there is greater uncertainty regarding catch levels and stock characteristics of minor tunas, limiting data to assess fishery impact on stock status. A report summarizes knowledge about the biology, stock structure, and recent catch of minor tunas; the main fisheries and fishing gears catching them; and their stock status in different oceans. The report also reviews available information on life-history characteristics, fisheries, and stock status, while identifying knowledge gaps that can inform research priorities.
