 note = {Some investigations on the five kinds of artificial bait of Vinyl Chloride shaped like a flying fish were carried out by the “Keiten Maru”, Training Ship of the Faculty of Fisheries, Kagoshima University, in the sea-fronts spreading over 1°-00’N~3°-00’S and 93°-00’E~95°-00’E, during the term from May 31 to June 23 1969. The material, length, form, and colour of the five kinds of artificial bait, are as shown in Fig. 1 and Table 2. A series of investigation were conducted in order to compare its efficiency with the real bait fish. The results obtained are as follows : 1) As shown in “C” and “D”, of the five kinds of artificial bait, the best hooked rate is 0.67%, and as shown in “B” and “E”, this is followed by the hooked rate of 0.33%, the last “A” being 0.17%. 2) According to the investigations on the artificial bait and the frozen Saury bait, the total hooked rate of the artificial bait, compared with that of the frozen Saury, was confirmed to be only one fifth. 3) The hooked rate of the first fifty baskets of the long line against that of the second fifty baskets next to the first ones was confirmed to be one half. Hence, it was assumed that the position in which the long line was attatched had close relationship with the hooking rate of the artificial bait. 4) It was assumed that the possibility of the artificial bait’s being left-out or damaged, was to be related not only to the quality of the artificial bait, but to the way the hook was fixed and handled ; some faults were observed while the long line was being set out or hauled up. 5) Fading in the artificial-bait-colour was occasioned in the operation, but no difference was to be caused in the hooking rate. 6) It has some faults in handling at the setting and hauling work of long line.},
