• The results of experiments to determine the success of a fishery with artifical baits for tuna long lines were as follows: In cases where fish oils and such (substances that emit a strong scent the for many hours) are used on the artifical baits as additional matter, the results compared with that where no additional matter has been used better. Remarkable differences in catch between (1) using glossy artifical baits of light red brown and (2) dull artifical baits of light yellow white were noted. The shape and attaching method (to tuna hooks) of the artifical baits and also the structure of fishing gears (Tsurimoto) exert influence on the hooking ability and fishing efficiency. Artifical baits should be tough and strong to withstand attacks by fish.
