Hawaii longline tuna fishery temporal trends in standardized catch rates and length distributions and effects on pelagic seamount ecosystems
Target catch
Tuna
Study Type
Field study in the wild
Effect on target catch
All tuna species had higher catches rates when wider circle hooks were used. Shortfin spearfish and striped marlin catch rates were lower with circle hooks. No differences in average length between hook types.
Effect on bycatch species
Reduced sea turtle interactions likely due to use of circle and not J hooks
Bycatch species
Sea Turtles
Fishing Gear
Hooks-and-Lines
Reduction technique
Circle hooks
