摘　　要：调查了烟威渔场主要底栖动物种类及使用拖网进行捕捞情况，分析了４０马力渔船所用２种拖网的结构、性能、渔捞效果，对１００～１８５马力渔船的传统拖网提出了采用双底纲、低口长袖、单拖作业等技术改进方向。Based on investigation of the main varieties of the benthic animals in the Yanwei fishing ground as well as the situation of fishing with trawls, the papar analysed the structure,property and fishing effect of two kinds of trawls used on the fishing boat fitted with 40 HP diesel,and put forward proposals for improving fishing technique,such as using double lead line,low net mouth and long net wing,single-trawling instead of the traditional trawl used on the fishing boats fitted with 100 or 185HP diesels.
