| 内容記述 | Following the results reported in the 1st paper, the same experiments were carried out during the term from 23rd of May to 14th of June 1971, mostly on the Coral Seaon board the fishing training-ship “Kagoshima Maru”. The results obtained are as follows : 1. In case of the tuna-fishing, the hooking rate of round scad showed the highest rate of 5.38% : those of saury and mackerel being 4.76% and 3.04% respectively. In case of marlin and sword fish, the hooking rate of mackerel sowed a comparatively high rate of 0.65%, those of round scad and saury being 0.32% and 0.11%, respectively. 2. Concering the average hooking rate in the total covering the two sorts of fish, tuna and marlin ; round scad showed the highest rate of 5.70%, which was superior to that of 4.86% showed by saury. 3. As to the dropping rate of the bait, saury showed the highest rate of 68.9% ; one of the dropping-causes was ascertained to by due to the fact that the bait was hooked un-melted. 4. These hooking rates are assumed to be influenced by some differences in the motions, in the flowing water, of these three kinds of baits, saury, round scad and mackerel. 5. In short, the possibility of using the frozen round scad for a bait of tuna-long-line was ascertained in these experiments. | |||||
