摘　　要：为充分开发利用地方性、区域性和养殖区内的小型鱼虾贝类资源，对８．８ｋＷ渔船单拖网网具结构进行了设计。在乳山和海阳沿海进行了单、双拖网捕捞对比试验，并扩大推广。结果：单拖比双拖作业增产增值３５～７０％，经济效益显著，且对传统经济鱼虾类资源有一定保护作用。专家鉴定认为，本项目达到国内领先水平。For the purpose of full developing the local,regional small sized fishes,shrimps,shellfishes resources and those in the cultivation areas,a single drawing net was designed for using on the fishing boat with the power of 8.8 kW.A contrastive fishing experiment between the single and double drawing net was made in the coastal waters of Rushan and Haiyang cities.The experimental result showed that the catch of the single drawing net increased by 35～70% more than that of the double drawing net.Its economic benefit was much clearly.Further more,the single drawing net has a function to protect the resources of the traditional economic fishes and shrimps.The achievement,appraised by experts,was in the lead at home.
