Effect on bycatch species
Highly significant reduction in the proportion of turtles that swallowed hooks
Effect on target catch
Swordfish catch increased by 16%, tuna catch decreased by 50%, and mahi-mahi, opah, and wahoo catch decreased by 34%
Bycatch species

Effects of eliminating shallow hooks from tuna longline sets on target and non-target species in the Hawaii-based pelagic tuna fishery

Study Type
Field study in the wild
Location
Hawaii

Tuna and swordfish
Effect on bycatch species
No differences in catches between experimental and control sets
Effect on target catch
Decreased catch of wahoo, dolphinfish, blue and striped marlin, and shortbill species, increased catch of sickle pomfret and opah, and did not affect catch of sharks and pelagic sting rays
Bycatch species
Sharks
