根据农牧渔业部水产局下达的“294.2千瓦综合节能渔船”项目网具节能课题的要求,新设计了一项低阻底拖网,并进行了网模水池试验和海上实测及一周年商业性捕鱼生产,获得了很好的效果。试验和捕鱼生产结果充分证明:新设计的拖网网口高、阻力小、渔获量高,是一种较为理想的节能型双船底拖网网型,具有增产节能兼优的经济效益和社会效益。
According to the requirements of the energy saving project of “294.2 kilowatts comprehensive energy-saving fishing vessel” project issued by the Fisheries Bureau of the Ministry of Agriculture, Animal Husbandry and Fisheries, a low-resistance bottom-trawling net was newly designed and tested by net-mold pooling, measured at sea and one-year commercial catches Fish production, got good results. The test and fishing production results have fully proved that the newly designed trawl mouth has the advantages of high mouth resistance, small resistance and high catches, which is an ideal energy-saving double-bottom trawl net with economical and social benefits of increasing output and saving energy .
