April 2, 2023 — A new report by the International Seafood Sustainability Foundation (ISSF) has found that only eight of 23 major commercial tuna stocks avoid overfishing and maintain biomass targets when measured against Marine Stewardship Council (MSC) standards.
The report, “An Evaluation of the Sustainability of Global Tuna Stocks Relative to Marine Stewardship Council Criteria,” found that only Western Atlantic skipjack, North Atlantic albacore, South Atlantic albacore, Eastern Atlantic bluefin, Western Pacific skipjack, Eastern Pacific yellowfin, Eastern Pacific skipjack, and Indian Ocean skipjack achieve a passing score for “sustainable fish stocks” when measured against MSC criteria. According to ISSF, an increased number of stocks failed to meet the MSC standard because managing bodies failed to implement harvest-control rules within the past year.
