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 supe...
