Night sets
|
Seabirds | Field study in the wild | Night sets reduce bycatch of seabirds in the Hawaiian swordfish longline fishery. |

Gillnets and Entangling Nets
|
Salmon | Seabirds | Field study in the wild | Opaque mesh netting placed strategically on gillnets decreased bycatch of rhinoceros auklet (Cerorhinca monocerata) and common mure (Uria aalge) seabirds but also decreased catch of target salmon species in the Puget Sound, USA. |

Side sets
|
Seabirds | Field study in the wild | Side-setting in combination with a bird curtain resulted in the lowest seabird-- Black-footed albatross (Phoebastria nigripes) and Laysan albatross (Phoebastria immutabilis)--capture rate when placed on pelagic longline gear for tuna and swordfish in Hawaiian waters when compared to underwater setting chutes and blue-dyed bait. Resulted in lowest capture rate when used with bird curtain |

Side sets
|
Seabirds | Field study in the wild | Side-setting of longline fishing gear in the western North Pacific deterred seabirds-- Black-footed albatross (Phoebastria nigripes) and Laysan albatross Phoebastria immutabilis)?from taking bait and improved the sinking rate of baited hooks. Deterred seabirds from taking bait |

Sub-surface sets (gillnets)
|
Seabirds | Field study in the wild | 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. |

Dyed bait
|
Seabirds | Field study in the wild | 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. Reduced bycatch but least effective of 3 tested techniques |

Acoustic deterrent devices
Visual deterrents
|
Seabirds | Field study in the wild | Acoustic pingers reduced the bycatch of the Common Murre (Uria aalge) in the Puget Sound salmon drift gillnet fishery, but they did not reduce bycatch of the rhinoceros auklet (Cerorhinca monocerata). Reduction of target species catch was not significant.
White gillnet mesh panels in the upper portion of the net reduce the bycatch of seabirds (Common Murres and Rhinoceros Auklet) in the Puget Sound salmon drift gillnet fishery. Rhinoceros Auklet bycatch was only reduced in 50-mesh visual alert nets. The white mesh panels decreased salmon catch in 50-mesh but not in 20-mesh. Variable depending on seabird species |
