Description:

This study provides empirical evidence which suggests that for a tuna fishery in the Pacific Ocean, adoption of a larger hook could provide increased catchability of retained species while simultaneously serving as a conservation tool by decreasing catchability of a majority of bycatch species. With the exception of higher catchability of blue shark, the primary elasmobranch species caught, larger hook size implementation could reduce overall discards.
