为促进我国海洋渔业"走出去",进一步发展远洋捕捞业,文章调查西南大西洋乌拉圭近海双船拖网捕捞的渔具和渔法等,并提出生产建议。研究结果表明:双船拖网的渔具包括渔船、网具、纲索和属具,网身采用加目和减目编缝的方式缝合而成;渔法包括放网准备、放网、曳网、起网和网具养护等环节;针对渔场、渔期和捕捞对象,应把握捕捞产量、成本和航次的关系,并结合主捕对象的生活习性,合理规划生产。

In order to promote the "going out" policy of China′s marine fisheries and further develop the pelagic fishing industry,this paper investigated the fishing gear and fishing methods of double-boat trawling in the south-west Atlantic Ocean of Uruguay,and put forward some suggestions for production.The research results showed that:the fishing gear of double-boat trawler included fishing vessel,netting gear,outline rope and genus gear,and the net body was stitched together by adding and reducing eyes;the fishing method included netting preparation,cast netting,seine netting,haul the net and netting maintenance.According to the fishing ground,fishing period and fishing object,we should grasp the relationship between fishing yield,cost and voyage,and plan the production reasonably according to the living habits of the main fishing object.
