This report presents the outcomes of the APEC workshop held in December 2024 in Lima, Peru, focused on strengthening traceability systems and combating Illegal, Unreported, and Unregulated (IUU) fishing. It documents the exchange of experiences among APEC economies, highlighting best practices, challenges, and opportunities in both industrial and small-scale fisheries. The report combines findings from a regional survey and the workshop’s collaborative sessions, which led to the development of five key pillars: harmonized standards, verified traceability, integration of enforcement, IT continuity and innovation, and strategic communication. Case studies from economies like Chile; China; Indonesia; and Peru showcase practical solutions, such as mobile apps and AI for traceability. The report concludes with actionable recommendations, a roadmap for future collaboration, and pilot initiatives that aim to scale successful approaches across the region, reinforcing APEC’s role in fostering sustainable fisheries management.
