World Tuna Day

  Southern bluefin tuna (Thunnus maccoyii) is assessed and managed by the Commission for the Conservation of Southern Bluefin Tuna (CCSBT). Practically all of the catches are made in the IOTC, ICCAT and WCPFC convention areas (62 percent in the Indian Ocean, 25 percent in the Pacific Ocean and 13 percent in the Atlantic Ocean). Southern bluefin tuna catches in 2023 were approximately 17 300 tonnes, reflecting a 1 percent increase from 2022. Catches rose sharply from the beginning of the fishery around 1950, reaching a record high of 81 000 tonnes in 1961. However, they then declined continuously until 2011, when the lowest recorded catch of 9 459 tonnes was reported (FIGURE E.1.19). Since then, catches have been gradually increasing to the current level of 17 300 tonnes, largely due to strict catch limits established under the Southern Bluefin Tuna Management Procedure. This procedure, initially known as the “Bali Procedure” (adopted in ...

  About 23 percent of the world’s tuna production comes from the Indian Ocean (IO) – FAO Major Fishing Areas 51 and 57–making it the second most important region for tuna fishing after the Western and Central Pacific Ocean. Catches of skipjack, yellowfin, bigeye and albacore tuna in 2023 totaled approximately 1 237 000 tonnes, a 1 percent decrease from 2022. The total catch generally declined after 2005, when a record 1.25 million tonnes were caught, followed by an increase in recent years which has brought catches back to 2005 levels (FIGURE E.1.16). Catches of southern bluefin tuna occur primarily in the IO Area of Competence. However, due to their distribution across three oceans, this stock is covered below under a separate section on the CCSBT convention area. The catch of tropical tunas and albacore tuna in the IO steadily increased, reaching 200 000 tonnes in the early 1980s. It then rose rapidly to 500 000 tonnes in 19...

  About 11 percent of the world’s tuna production comes from Atlantic Ocean (AO) stocks –FAO Major Fishing Areas 21, 27, 31, 34, 41 and 47. Catches of skipjack tuna, yellowfin tuna, bigeye tuna, albacore tuna and bluefin tuna in 2023 totaled 544 700 tonnes, a 9 percent decrease from 2022 levels. The total catch has generally declined since the mid-1990s, followed by an upward trend since 2009 (FIGURE E.1.13). The catch of tropical tunas (bigeye tuna, yellowfin tuna and skipjack) in the AO initially steadily increased by approximately 100 000 tonnes per decade, reaching 100 000 tonnes in 1963, 200 000 tonnes in 1971, and 300 000 tonnes in 1980. It then quickly rose to 0.4 million tonnes by 1982, before reaching 500 000 tonnes in 1994. Total catches declined to 300 000 tonnes in 2006 but then began increasing again, reaching a historical high of 520 000 tonnes in 2018. Since then, catches h...
