IUUFischerei

IUU fishing stands for illegal, unreported and unregulated fishing. It refers to fishing activities that violate applicable laws, fail to report catches to authorities, or occur without proper regulatory oversight. IUU fishing can take place on the high seas or within national waters and often involves misrepresented documents, transshipment at sea, and evasion of port controls.

Illegal fishing includes operations that surpass quotas, fish in protected or closed areas, use prohibited gear, or fish without valid licenses. Unreported fishing involves catches that are not reported, or are misreported, to conceal the true scale of exploitation. Unregulated fishing is conducted by vessels operating without recognition or without effective oversight by flag states, coastal states, or regional management bodies.

The practice undermines sustainable fisheries by eroding stock productivity, distorting market competition, and reducing revenues for compliant fishers and governments. It can threaten food security, biodiversity, and the economic health of coastal communities, especially in regions with weak governance or limited enforcement capacity.

Governance and countermeasures rely on international law, scientific advice, and cooperative enforcement. Key frameworks include the United Nations Convention on the Law of the Sea (UNCLOS), the FAO Code of Conduct for Responsible Fisheries, and regional fisheries management organizations. The Port State Measures Agreement strengthens inspections of fishing vessels at ports, while catch documentation schemes, vessel monitoring systems, and data-sharing networks aim to improve traceability and accountability. Despite progress in some regions, enforcement gaps, limited resources, and transnational operations continue to challenge global efforts to reduce IUU fishing.
