Summary
Two types of tori-lines (tori-line and tori-line light streamer) were tested aboard commercial and research longline vessels in the western North Pacific to determine their effectiveness for seabird avoidance. The tori-line light streamer reduced bait-taking behavior (in primarily Laysan albatross, Phoebastria immutabilis) and bycatch of seabirds (primarily Laysan albatross) compared to the tori-line. Therefore, the tori-line light streamer is a good option for avoiding seabird bycatch in this longline fishery.
