A retrospective analysis evaluated how mitigation measures in Hawaii (U.S)'s shallow-and deep-set longline fisheries influenced the probability of interaction and disposition (alive v. dead) of Laysan (Phoebastria immutabilis) and black-footed (P. nigripes) albatrosses. Most mitigation measures efficiently reduced seabird bycatch, however, few influenced whether interactions were fatal. In the shallow-set fishery, side-setting and stern-setting proved equally effective. Night-setting is highly effective at reducing interactions, though interaction and mortality rates were much higher during the full moon, when most shallow-set effort occurs. The use of blue-dyed bait and strategic offal/bait discharge were associated with increased interactions.
