Abstract：Tuna fishery occupies an important position in the world fishery,and is the key development industry of fishery countries and regions in the world.Based on the major tuna catch data of the world from 1950 to 2019,combined with tuna trade data,population data and GDP data of countries and re-gions around the world,the status of the world tuna fishery was summarized.The results showed that the catch of major tuna trends obviously to increase from 1950 to 2019,but the catch each species vary each other.The cumulative total catch of Katsuwonus pelamis was the highest and its average growth rate each generation was the highest.The catch of the three major bluefin tuna was low,and the aver-age growth rate of Thunnus thynnus and Thunnus orientalis was negative each decade.The catch of tu-na was greatly different among countries and regions.The total catch of major tuna of 6 developed countries and regions including Japan and the United States accounted for 56.68％of the total while that of Chinese mainland only accounted for 1.02％.In addition,the total tuna catch of 11 island coun-tries with the highest per capita tuna catch and Marshall Islands sparsely populated and rich in resources was only 4.30× 104t in 2013,Less than 10％of Japanese catch.The United States,Japan and other de-veloped countries and regions stood at the top of the world in the global economic development firmly controled the fisheries regulations of tuna in the high seas and the right to set quotas,and then the global trade in tuna.Among them,the trade volume of major tuna in Japan accounted 25％of the glob-al trade volume.The results also indicated that the tuna in the high seas are the precious resources for universal,not specific to a small number of countries and regions.To truly realize the sustainable de-velopment for world tuna fishery and the blue growth target advocated by FAO,the existing system of rule of inequality and injustice should be broken,the principle of humanity sharing blue ocean economy of new rules and new order should be formulated newly.
