东海水产研究所渔捞研究室拖网组于1988年承担了中国水产科学研究院下达的“拖网渔具优化设计及性能的研究”的研究任务,经过三年来的努力,在对全国16顶具有代表性的拖网分析研究的基础上,又进行了6个系列的拖网模型试验,获得了大量的技术数据,并以此为依据,于1990年9月研制了1顶270马力对拖作业的“优化设计”试验网(简称优化网)。在常熟市海洋渔业公司3125、 The Fishing Trawl Trawl Group of the East China Sea Fisheries Research Institute undertook the research task of “Research on the Optimization Design and Performance of Trawl Gear” issued by the Chinese Academy of Fishery Sciences in 1988. After three years of hard work, On the basis of trawl analysis and trawling, and carried out six series of trawl model tests, obtained a large number of technical data, and on this basis, in September 1990 developed a 270 horsepower drag on the “optimal design ”Test network (referred to as optimization network).
