85% of Global Tuna Catch Comes from Stocks at Healthy Levels; 11% Require Stronger Management
Of the total commercial tuna catch worldwide, 85% 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, 11% of the total tuna catch came from overfished stocks, and 4% came from stocks at an intermediate level of abundance.
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 and income for coastal communities.
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. An ISSF 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.
Interactive Stock Status Tool
An interactive tool allows you to visualize current and historical data from ISSF’s Status of the Stocks report, which scientifically assesses 23 commercial tuna stocks worldwide. The tool has two tabs — one for visualizing tuna stock health since 2011, and another for visualizing the current tuna catch by fishing method.
