This analysis demonstrates the impact of fishing effort reductions on bycatch levels in mixed fisheries, suggesting effective management practices.
Strict implementation of the landing obligation helps to secure sustainable management of bycatch species. • Reductions in fishing effort were necessary in all performed simulations to bring unintended bycatch to sustainable levels for as many of the examined species as possible. • Alternate management measures – such as more selective nets or closures of fishing areas – sometimes resulted in less efficient fisheries and higher fishing effort in order to compensate, which reduced the positive effect on bycatch mitigation. Such downstream effects are often missed.
