Dyed bait, alternative offal discards, bird-scaring devices (streamer lines & towed buoys), and night sets reduced seabird (Black-footed (Phobastria nigripes) and Laysan (Phoebastria immutabilis) albatrosses) bycatch in the Hawaiian swordfish and tuna longline fisheries. Alternative offal discards worked by distracting seabirds from hooked bait. Dyed bait did not affect the catch of target and marketable species (all marlin and tuna species, swordfish, shortbill spearfish, opah, wahoo, and dolphinfish), but it reduced catch of blue sharks.
