为合理开发利用地方性、区域性和养殖区内的小型鱼虾贝类资源，对 １４． ７ ｋＷ渔船单拖网网具与网板进行了试验研究，在乳山、海阳沿海进行了单、双拖网捕捞对比试验，并扩大推广。结果，单拖网比双拖网增产增值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。
In order to rationally develop and utilize small-scale fish and shellfish resources in endemic, regional and aquaculture areas, The 7 kW single-trawler fishing net with stencil was tested and studied. Single-and double-trawled fishing comparative tests were carried out in Rushan and Haiyang coastal areas, and the promotion was expanded. As a result, single-trawl net increased 35% ~ 70% more than double-trawled net, with obvious economic benefits and some protection to traditional economic fish and shrimp resources. Experts believe that this project has reached the leading domestic level.
