The effect of two hook types (J-style and circle) and two bait types (jumbo squid and juvenile striped mullet) were tested on pelagic longlines in the northwest Pacific Ocean to determine their effect on catch rates of pelagic species.  There were no significant differences in catch rates between hook types, but squid bait caught significantly more blue and silky sharks and dolphinfish.
