鹰爪虾(Trachypenaeus curvirostris)是黄海北部的重要捕捞对象之一,其中山东省全年捕获量一般为3000～7000吨,近几年资源旺发,产量可达万吨以上。应用普通拖网捕捞鹰爪虾,不仅产量低,而且网具损坏和丢失严重。针对这种情况,山东省海洋水产研究所,从1981年开始改革鹰爪虾拖网。经过反复试验,于1984年研究成功装有驱虾装置的鹰爪虾拖网。连续四年的生产实践证明,该网比普通网增产鹰爪虾30～50％,并且在渔获物中杂质少,网具寿命长。
Trachypenaeus curvirostris is one of the important fishing targets in the northern part of the Yellow Sea. Among them, the annual catch of Shandong Province is generally between 3,000 and 7,000 tons. In recent years, resources have been booming and the output can reach over 10,000 tons. The application of ordinary trawling Hawk claws shrimp, not only low yield, but also damage and loss of nets serious. In response to this situation, Shandong Institute of Marine Fisheries, since 1981 reform Eagle claw shrimp trawling. After repeated tests, in 1984 the successful study of the shrimp shrimp claw shrimp device installed trawling. For four consecutive years of production practice has proved that the network increased production of Cape claw shrimp 30-50% than ordinary network, and less impurities in the catch, net long life.
