我们在76年末设计了135马力机帆船使用的适应南方渔场主捕带鱼、花鱼的鱼拖网。于77年春分别在南京林产工业学院和广州中山大学做了拖网模型水槽试验(见《天津水产》77年3、4期),试验表明各项技术性能较良好,又进行了必要的修改织成实物网,于今年二月中旬破冰出海投人海上生产试验,截止4月20日经过四航次生产性试验(对船共投网117次,其中试验船投网49次,对
In late 76, we designed a fish trawling fish adapted for use on a 135-horsepower sailing ship to catch the fish and fish of the southern fishery. In the spring of 1977, a trawl tank trial was conducted at Nanjing Institute of Forestry and Guangzhou Sun Yat-sen University (see “Tianjin Fisheries” 77, 3, and 4 issues). The tests showed that the technical performance was better and the necessary modifications were made The physical network, in mid-February this year, ice-breaking into the sea to invest in offshore production test, as of April 20 after four voyage production test (a total of 117 pairs of ships on the network, in which the test ship cast 49 times,
