Hawaii longline tuna fishery temporal trends in standardized catch rates and length distributions and effects on pelagic seamount ecosystems



Target catch: 


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: 

Fishing Gear: 

Reduction technique:
