Bycatch species Sea Turtles | Type Field study in the wild | Results A chain mat placed on Northwest Atlantic dredge gear eliminated bycatch of sea turtles: loggerhead (Caretta caretta), leatherback (Dermocheles coriacea), and green sea turtles (Chelonia mydas). The chain mat reduced catch by 6.71%. |

Bycatch species Small Cetaceans (maximum length < 7.5 meters) | Type Field study in the wild | Results A quick-release metal wire added to the Florida king mackerel troll fishery reduced depredation of catch by bottlenose dolphin (Tursiops truncatus). There was no impact on king mackerel catch. |

Bycatch species Small Cetaceans (maximum length < 7.5 meters) | Type Field study in the wild | Results An excluder device, tested in the United Kingdom bass pair trawl fishery, reduced bycatch of common dolphins (Delphinus delphis). There was a negligible loss of target fish (<1%). |

Bycatch species Seabirds | Type Field study in the wild | Results 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. |

Bycatch species Sea Turtles | Type Field study in the wild | Results Turtle excluder devices reduce sea turtle and non-target finfish (Atlantic croaker (Micropogonias undulateus), spot (Leiostomus exanthurus), sea catfish (Arius felis), and weakfish (Cynoscion regalis)) bycatch in the Gulf of Mexico prawn trawl fishery. Catch of targeted shrimp varied by location and TED configuration, but there was no significant difference in shrimp catch rates in 3 of the 4 TEDs when compared with a control net. One experimental TED in Texas exhibited a decrease in shrimp catch. |
