摘要
根据FA0 1950 ～ 2011年世界主要金枪鱼类渔业生产数据统计,将长鳍金枪鱼、黄鳍金枪鱼、大眼金枪鱼和鲣鱼等8种世界主要金枪鱼类每10年的产量总和按不同鱼种和海域进行了总结.结果显示,鲣鱼的累计总产量最高,其平均年产量涨幅最快;除马苏金枪鱼年平均产量有所下降,北方蓝鳍金枪鱼保持稳定外,其他主要金枪鱼类均有增长,但平均增长率最高的是青干金枪鱼.各主要渔区中以中西太平洋海域累计总产量最高,平均年产量有上升趋势,大西洋海域以中东大西洋为产量最高,印度洋海域以西印度洋为产量最高,平均增长率以印度洋海域为最高,其他海域相对持平.我国（包括台湾省）捕获累计总产量最高的是鲣鱼,为418×104 t,占世界总产量比例最高的是长鳍金枪鱼,为22.9％.我国（包括台湾省）主要金枪鱼类捕获总产量占世界总产量比例最高为东南大西洋海域,最低为东南太平洋海域.论文结合世界主要金枪鱼类以及主要捕捞海域的开发现状和我国国情,提出我国目前面临的几点困难以及发展壮大我国金枪鱼渔业的建议.
According to fishery production statistics from FAO, regional data on the world＇s major tuna species from 1950 to 2011 were analyzed. The average catch data of albacore, yellowfin tuna, bigeye tuna, and skipjack tuna were summarized and analyzed in decades according to different fishing areas respectively. The results showed that the highest accumulative total production was skipjack, and its average annual increase rate was also the fastest. The average annual catch of southern bluefin tuna declined, northern bluefin tuna kept as usual, and other major tuna species increased, but the highest average growth rate in catch was in longtail tuna. The highest total production in the Pacific Ocean was in the western-central Pacific, where the catch showed a rising trend. And the highest total production in the Atlantic was in the east-central Atlantic, and the highest total production in the Indian Ocean was in the west Indian Ocean. The highest average growth rate in catch was in the Indian Ocean while others were relatively flat. In China （including Taiwan）, the highest accumulative total production for species was skipjack, while the highest proportion of the total production in the world was albacore. For Chinese tuna fisheries （ including Taiwan）, the highest proportion of major tuna species＇ production in the world was in the south-east Atlantic, and the lowest was in the south-east Pacific. Combined with the status of the world＇s major tuna fisheries and Chinese tuna fisheries development, several difficulties and suggestions for developing and expanding our tuna fishery were elaborated.
