Vessel-specific management

Bycatch rates can vary among fishing vessels operating in the same fishery, even after accounting for factors such as vessel size and fishing effort, and these differences can persist from year to year. However, it is very difficult to separate out the factors influencing vessel performance. Likely factors include the skill with which mitigation measures are implemented, the vessels' fishing patterns compared to the spatial and temporal distribution of bycatch species, and their willingness to move away when bycatch rates increase.
