Tridge summary

A recent report by the International Seafood Sustainability Foundation (ISSF) indicates that some tuna stocks are overexploited and overfished. Notably, the Mediterranean albacore, bigeye, and yellowfin tuna in the Indian Ocean, as well as the bluefin tuna in the Pacific Ocean, are undersir. The report also highlights changes in the classification of tuna stocks since the last update, such as the Indian Ocean bigeye tuna stock's biomass rating changing from green to orange. Overall, 61% of 23 stocks are at healthy abundance levels, but 17% are overexploited. The total catch of the main commercial tuna populations in 2021 was 4.8 million tons, with skipjack tuna accounting for 56% of this figure.

Some tuna stocks are considered overexploited and/or overfished. For example, stocks of Mediterranean albacore, bigeye and yellowfin tuna in the Indian Ocean are being overexploited and overfished. Bluefin tuna in the Pacific Ocean is overexploited. The report notes several changes in the classification of tuna stocks since the last update in November 2022: since the last report, the biomass rating of the Indian Ocean bigeye tuna stock has changed from green to orange. The fishing mortality rate of the albacore population in the Indian Ocean has changed from orange to green. The International Commission for the Conservation of Atlantic Tunas (ICCAT) is adopting a new management procedure for western and eastern Atlantic bluefin tuna populations. ISSF publishes its flagship stock status report several times a year with the latest scientific data on 23 major commercial tuna stocks. Abundance levels or “spawning biomass”: Globally, 61% of 23 stocks are at healthy abundance levels ...
