摘要
１９９３～１９９５年，先后设计和试验了网口目大６ｍ、８ｍ、１０．８ｍ３种规格拖网，普遍增产２０％以上。本文着重介绍１３６ｋＷ渔船使用的网口目大８ｍ的拖网设计方法及试验情况，提出根据捕捞对象习性选择网身形状，根据网衣受力和渔船功率配置网线。
From 1993 to 1995 a rope trawl with different mesh sizes of 6 m,8 m and 10.8 m in the part of the net mouth was designed.In the fishing test its catch increased by 20%.The article focused on introducing the design method and test result of the rope trawl with its net mouth mesh size of 8 m for 136 kW fishing vessel.The net twine for making rope trawl and its form were especially stressed on study.The design method was based on the force endurance of the net to dispose the netting cord and on the habits of the fishing stock to choose the net body form.
