Bycatch of marine mammals is a major threat to their conservation and a global management issue. Traditional regulations are often ineffective, highlighting the need to explore incentive-based approaches that combine economic and social motivations. This study proposes a framework for assessing the feasibility and sustainability of such incentive-based strategies. Seven case studies are analyzed to demonstrate the applicability of this framework in various contexts. The analysis emphasizes the importance of local data collection, credible threats, fishermen involvement, and the role of collective organizations.
