Effects of eliminating shallow hooks from tuna longline sets on target and non-target species in the Hawaii-based pelagic tuna fishery
Target catch
Bigeye tuna (Thunnus obesus)
Study Type
Field study in the wild
Effect on target catch
Experimental gear caught 22% more bigeye tuna than the control gear
Effect on bycatch species
Reduced catch of shallow-dwelling non-target sportfish and billfish; increased catch of deeper-dwelling marketable species
Bycatch species
Bony Fishes
Juvenile/Non-target fishes (not specified to species level)
Fishing Gear
