【摘要】 由于手钓在北太平洋柔鱼捕捞作业中占有重要地位,本文对影响手钓渔获产量的几种技术因素作了实际测试和一定的分析,包括:抖动频率、每次抖动时间、拉线速度等。实际测试结果表明,对于捕捞体重为2kg左右的柔鱼,其以上三种技术指标的适宜范围分别为5次/min、2.16S/次、70～75m/min。更多还原

【Abstract】 Hand jigging operation,plays an important role in the squid jigging fishery in NorthPacific Ocean. Based on field measurements, this paper analyzed the main technical factors affecting hand jiiging effciency, including jigging rate, jigging cycle and hauling up speed of hand jigging line, and concluded that the suitable technical indexes were as follows; 1) jigging rate; 5 times/s, 2) jigging cycle; 2. 16 s/time, 3) hauling up speed; 70-75m/s.更多还原
