Summary: 
Underwater setting chutes, blue-dyed bait, and side-sets each reduced the bycatch of seabirds (Laysan and black-footed albatross and short-tailed shearwater) in the Hawaiian longline tuna and swordfish fisheries. Side-sets showed the most promise for a bycatch mitigation technique while blue-dyed bait was the least effective at reducing seabird bycatch and shows the least promise of these methods as an effective bycatch mitigation strategy.
