Pacific patrols nab two suspected illegal tuna fishing vessels

Illegal fishing in the western and central Pacific is not an abstract enforcement issue. It hits tuna availability, weakens stock tracking, and undercuts the lawful operators and island nations that depend on a fair fishery, which is why two suspected illegal vessels caught in a regional sweep matter far beyond the arrests themselves.

Operation Tui Moana 2026 ran from May 4 to May 22 across the exclusive economic zones of 10 Pacific Island states and adjacent high seas waters. The Pacific Islands Forum Fisheries Agency said the campaign involved Cook Islands, Fiji, Kiribati, Niue, Papua New Guinea, Samoa, Solomon Islands, Tokelau, Tonga and Tuvalu, with support from Pacific Quad partners Australia, New Zealand, France and the United States. By the end of the operation, authorities had verified more than 200 vessel detections, carried out 61 at-sea and port inspections, identified four vessels of interest and followed through with two apprehensions.

The suspected violations give a clear picture of how IUU fishing often looks in practice. The FFA said the cases involved vessel monitoring system non-reporting, unauthorized bunkering and transshipment, and problems with logsheet documentation and reporting compliance. Those are the kinds of breaches that blur where fish came from, how much was taken, and whether the catch stayed inside the rules that protect tuna stocks and license holders alike.

The operation was coordinated through the FFA Regional Fisheries Surveillance Centre in Honiara, Solomon Islands, using the Regional Surveillance Picture, the Regional Information Management Facility and Starboard Maritime Intelligence to flag higher-risk vessels and steer patrols toward them. The effort combined surface patrols, aerial surveillance and intelligence analysis rather than relying on a single method. Cook Islands Police said Te Kukupa II boarded 13 fishing vessels during the sweep and also encountered three yachts. In parallel support under Operation Solania, the Australian Defence Force said its patrols covered 113,220 square kilometres and identified 12 vessels of interest suspected of illegal fishing in the Tonga and Cook Islands EEZs.

The stakes are high because the WCPO remains the engine room of global tuna fishing. The Western and Central Pacific Fisheries Commission says the convention area recorded an estimated 3.059 million metric tonnes of tuna catch in 2024, a record high. Australia says the Western and Central Pacific Ocean accounts for around 55% of global tuna production, with about half of that catch coming from Pacific island EEZs. For the tuna fleet, that makes stronger enforcement in the region a direct line between healthy stocks, clean catch reporting and a fishery that still rewards the operators playing by the rules.
