"Illegal, unreported and unregulated (IUU) fishing is a crime with global reach. The links between IUU fishing and other transnational crimes are well established. With its focus on Jamaica and its territorial waters, this article evaluates the intersection of policy design and its instruments (legal–regulatory tools, economic and financial tools, and information tools) with Jamaica’s attempts to curb IUU fishing. The article finds that while progress is occurring, more can be done. This includes signing key international treaties, improving data collection and analysis, deepening information exchanges, and encouraging sustained political will."
