摘    要:作者根据中国沿海现有几十种较有代表性的底层有翼单囊拖网网具资料,统计了大量的网具设计参数,并根据拖网的结构特征和作业性能来分析研究结果,认为在中国沿海拖网渔业生产中,使用较多、效果良好并具有一定代表性的底层有翼单囊拖网的网型,主要有尾拖型、疏目型、改进疏目型和编结型四种,并认为这四种网型的作业性能可简单地归纳为:改进疏目型为高口中速;尾拖型为中口中速;编结型为中口高速;疏目型为低口快速。

关 键 词:拖网  网型  底层拖网

Abstract:According to the netting structure and operation condition, the netting types of China's coastal bottom trawl are analysed in this paper. Several decades of typical trawl with a bag and wings used in offshore waters have been researched. A vast amount of statistics on netting design parameters have been made and analysed by the factors of netting structure and operation condition. It is finally considered that four netting types of bottom trawl are widely and effectively used in China. They are stern trawl, trawl with large mesh,trawl with large mesh improved and braided trawl. These trawls mentioned above meet the different requirements for their working conditions around all the offshore waters in China. To sum up, the four netting types of trawl have their own performances. The trawl with large mesh improved means high opening of mouth and mid-speed, stern trawl means both of medium,braided trawl means mid-opening of mouth and higher speed, and trawl with large mesh means low opening of mouth and higher speed.
Keywords:trawl  netting type  analysis
