大西洋大眼金枪鱼资源开发研究

Developing Research of Bigeye Tuna Resourses in the Atlantic Ocean

统计分析了1995-2004年间大西洋大眼金枪鱼总渔获量及各渔区、各主要生产国的渔获量变化情况,结果表明:整个大西洋大眼金枪鱼渔获量呈下降趋势,其开发类型主要有延绳钓、饵钓和围网,其中以延绳钓的渔获量最大,1995-2004年期间以西北大西洋(21区)产量最高,为9.53×107t,东北大西洋与中西大西洋相对渔获量较少,各为2.47×104t,我国对大西洋大眼金枪鱼开发程度不高,占总渔获量的比例较小,针对我国的情况提出开发大西洋大眼金枪鱼相关建议。

By the method of statistics and analysis,the gross catch of Big eye Tuna in the Atlantic Ocean in the year 1995 to 2004,and the varied catch in each fishing zone and the major producing nations have been collected.It is demonstrated that the catch of Bigeye Tuna in the Atlantic Ocean is wholly going down.In the main,longline,baitboat and purse seine have been applied with the highest catch by longline.With an output of 9.53×10^7t,the north-west Atlantic Ocean outweighs north-east Atlantic Ocean and west-middle Atlantic Ocean,which have an output of 2.47×10^4t respectively.The developing of Tuna in the Atlantic Ocean in our country remains an unfavorable position accounting for a small percentage in the total catch.Some related suggestions are made to develop Big eye Tuna in the Atlantic Ocean by taking into consideration the situation in our country.
