| 摘 要： | 笔者曾对挪威鲱鱼围网的下纲沉降深度在围捕作业中进行了测试。本文根据海上实测数,对围网下纲沉降特性进行了理论分析,探求下纲沉降变化规律以及收绞括纲和投网速度对下纲沉降的影响。在此基础上对围网设计和围捕操作提出了一些建议。

| Abstract: | The writer has ever measured the depths of Norwagian herring purse seine during surrounding-fishing operation. In this paper, the theory on sinking characteristic of purse seine leadline has been analysed from the data measured on sea and the change law of leadline sinking has furtner been searched after and the influence on leadline sinking has been studied for purseline to be pursed and the speed of shooting net. On the basis of the above analysis, the suggestions have been made on purse seine design and fishing operation. |
