中型单拖网渔船拖力与渔具系统匹配的研究

ON MATCHING TOWING POWER AND GEAR SYSTEM FOR MEDIUM STERN TRAWLER

中国有数十艘中型单拖渔船在大西洋中东部海域捕鱼,但对渔船拖力与网具、网板之间的匹配研究较少。作者经对三种不同型号渔船的测试,并同外国同类作业渔船进行对比分析,提出了网具、网板和纲索三者阻力的合理分配比例。同时提出确定渔具系统总阻力的方法。

Tens of medium stern trawIers from China have fished in the off-shore waters of Eastern Central Atlantic for several years. There is few report,however, On matching towing power, net and otter boards for Chinese vesselsrecently. According to measuring results for these three types of trawler with itsown gear and comparating with foreign trawlers,the drags of net, of otter boardsand of towing ropes in reasonable proportion to total drag are given in this.paper. The method or determing total drag of gear system is also indicated.
