一、对虾流网发展概况对虾流网是由挂网、锚网逐步改进演化而来的。很早以前,我省东部昌黎,抚宁一带沿海渔民,先是用丝线织成的挂网在春季捕捞游向浅水的产卵亲虾。后来又逐步把原来的挂网改革成锚网(有的以石代锚),六十年代初期,为了繁殖、保护对虾资源,制定了以秋捕为主的方针,锚网的作业方式从浅水逐渐向深水,网的高度也都相应增加了。自七十年代初,又开始出现了不带锚的对虾流网。七十年代末,随着近海渔业调整,保护渤海鱼类资源及合 First, the development of prawn flow network Shrimp flow network is by hanging net, anchor network gradually evolved evolved.
