【摘要】 大西洋大眼金枪鱼（Ｔｈｕｎｎｕｓ　ｏｂｅｓｕｓ）是高经济价值鱼种，其分布几乎覆盖整个 大西洋水域。研究大西洋大眼金枪鱼的渔业对于我国远洋渔业意义重大。所以在此 对其渔业及资源状况进行研究。根据三种主要渔业（延绳钓、围网和竿钓）的渔获量， 可看出大眼金枪鱼渔业的发展概况。为了分析资源状况，文中使用了Ｗａｌｔｅｒｓ ａｎｄ Ｈｉｌｂｏｒｎ（１９７６）产量模型。其结果是９９．６千公吨的最大持续产量和１１４，７６０作业日的 最佳捕捞努力量。与目前约２００，０００作业日的努力量水平相比，资源处于过渡捕捞 状态。因此，应该采取一些管理手段来减少捕捞努力量，使资源恢复到最佳状态。更多还原

【Abstract】 Atlantic bigeye tuna (Thunnus obesus) has high market value. It covers almost the whole Atlantic Ocean. The research about it is very important to our pelagic fishery. So the fishery and stock status are discussed in this article. From the catch of three main gears (longline, purse seine, baitboat), the development of its fishery can be seen. For the analysis of the state of stock, Walters and Hilborn (1976) production model is used here. The production model produced a maximum sustainable yield (MSY) of 99.6 Kilo-MT and an optimum fishing effort (f_opt) of 114.76 Kilo-fishing days. In comparison with the current fishing effort level of about 200 Kilo-fishing days, the fishery is over-exploited, therefore management measures should be taken to reduce the fishing effort and then restore the stock to its best state.更多还原
