金枪鱼拟饵曳绳钓的试验研究

Experimental study on artificial lure of tuna trolling

报道了 1997～ 1998年期间金枪鱼拟饵曳绳钓作业上钩率的统计方法和拟饵曳绳钓作业的渔获种类数量、重量组成和体长组成的试验结果 ,与传统拖毛钓作业相比 ,上钩率按尾数计提高了4 8.5 % ,按重量计提高了 10 6 5 %。国产拟饵使用效果上钩率达到日本进口拟饵水平 ,并且具有易于操作 ,使用寿命长等特点。

The statistical method of hooking rate of artificial lure of tuna trolling and experimental result at sea were reported in this paper, including quantity composition of catch species, weight composition and composition of body length. Compared with the traditional method of trolling baited with goose feather during 1997～1998, the hooking rate increased by 48.5% by number of fish and 106.5% by weight. The home made artificial lures have as the same efficiency as compared with artificial lure from Japan, and have characteristics of long service life and easy operation.
