Abstract
We carried out test tuna longline operations using artificial bait made from liver of Japanese common squid (Todarodes pacificus) in January 1998. The angling performance of artificial bait and natural bait were compared. Tunas were caught using the artificial bait, but hooking rates were lower than two natural baits. In this paper, we discuss the effectiveness of the artificial bait.
Note: a large number of sharks were caught, though only a small proportion on the artificial bait.
