November 27, 2019 — The world’s major fishing nations have agreed “modest” quota cuts for the under-pressure Atlantic Bigeye tuna but critics say more should be done to protect an important food resource.
Scientists warn that unless the catch is reduced, stocks of Thunnus obesus—especially prized for sashimi in Japan and canned worldwide—could collapse within years.
A scientific report prepared for last year’s failed meeting of the International Commission for the Conservation of Atlantic Tunas (ICCAT) showed numbers had plummeted to less than 20 percent of historic levels.
This is only about half what is needed to support a “maximum sustainable yield”—the largest catch that can be taken without compromising the long-term stability of a species.
Going into the meeting in Majorca, Spain, ICCAT had a headline quota of 65,000 tonnes, allocated to the seven groups, including Japan and the EU, with the largest catch.
When smaller members were included, this rose to around 77,000 tonnes, pushing the Bigeye further into the danger zone, according to NGOs.
