The ever-accelerating process of introduction and establishment of invasive alien species (IAS) in marine waters requires engaging different actors in the management and planning. To address this challenge, stakeholders need an integrated approach for defining actions of control and management within an ecosystem-based framework: to seek and enhance coordination, collaboration and trust among all stakeholders affected by changes in linked marine social - ecological systems. This study explores the complexities and opportunities in managing economically valuable IAS, demonstrating the need for tailored management strategies that consider key ecological details needed for successful control such as timing of removals and key economic considerations such as appropriate incentive mechanisms and time horizons in favor of long-term conservation goals. We propose a set of actions that can serve as a roadmap for effective IAS control and management, considering their dual role as nuisances and valuable resources. These actions pertain to local, regional and international levels, encouraging meaningful stakeholder engagement through co-management structures that can foster the development of robust management plans, enabling better IAS control. The outcome holds potential for positive contributions to the blue economy— sustainable use of marine resources, including fisheries, tourism, and renewable energy— and for meeting sustainability objectives.
