该报告简述了鱼是鱼深水层流刺网具结构及特点。在鱼是鱼挂网的基础上,研制出60.00m×5.06—21.8mm鱼是鱼深水层流刺网具。在两只29.4kW渔船上进行了两年生产试验,生产171流次,捕鱼是528余吨,纯益14万元;与原型网对比,产量提高90%左右;推广10只渔船,捕鱼是963余吨,纯益21万元,取得较好的捕捞与经济效果。并简述了黄海北部产卵鱼是鱼生物学特性;得出了网目尺寸与鱼体叉长、体重、体周关系的各自相关系数;并对进一步开发利用鱼是鱼资源提出了建议。
The report outlines the structure and characteristics of the fish as a deep-water stinger. In the fish is hung on the basis of the net, developed a 60.00m × 5.06-21.8mm fish is a deep-water fish sting net. In two 29.4kW fishing boats on a two-year production test, the production of 171 times, fishing is 528 tons, net profit of 140,000 yuan; compared with the prototype network, the output increased by 90%; the promotion of 10 fishing boats, catch 963 tons of fish, net income 210,000 yuan, made better fishing and economic effects. And briefly described the biological characteristics of the fish in the northern Yellow Sea. The correlation coefficients between the size of the mesh and the length, weight and body length of the fish were obtained. Suggestions for further development and utilization of the fish as the fish resources were proposed.
