Tridge summary
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.
