Analysis and Discussion on trawlnet used by fishing vessels of China in Indonesian waters

本文探讨了中国渔船在印度尼西亚海域使用的拖网渔具 ,从渔具使用规格、缩结状态和结构等方面进行了分析 ,指出这类渔具在浅水渔场捕捞带鱼时有良好适应性 ,但局部配纲不当 ,网具贴底程度未达到最佳状态。由于网目大 ,有些局部改革可能导致敏感的负面反应。作者认为 ,这类网具今后的改革应着眼于提高拖速 。

This paper deals with the trawlnets used by fishing vessels of China in Indonesian waters. Based on the dimension,shrinkage and construction of the trawlnets,an analysis and discussion on the performance of this fishing gear are made.It shows that this kind of trawlnet is well suitable for catching hairtail in shallow waters,but the ropes of some sections are unsuitable to dispose,and the net in contact with sea bottom does not reach to the optimum condition. The reform in some parts of the net may lead to sensitive reactions due to the large mesh. In order to increase some high quality fishes,trawling speed should be raised in futtre reform of the net.
