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Waltirs and Hilborn(1976)产量模型。其结果是99.6千公吨的最大持续产量和114.7

关 键 词:大眼金枪鱼  金枪鱼  延绳钓  围网  竿钓  产量模型

Abstract:Atlantic bigeye tuna (Thunnas obesas) 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, baithoat), 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 (fopt) 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.
Keywords:bigeye tuna (Thunnus obesus)  longline  purse seine  haitboat  production model
