Sixteen vessels were identified as vessels of interest during a major regional operation targeting illegal, unreported and unregulated (IUU) fishing across Pacific waters, with four vessels detained or apprehended.

Operation Island Chief 2026, coordinated by the Pacific Islands Forum Fisheries Agency (FFA) from 3 to 14 August, covered about 27.5 million square kilometres and monitored more than 3,000 fishing vessels.

The operation analysed 10,884 satellite detections, recorded 92 vessel sightings and carried out 133 vessel boardings and inspections. Forty-five vessel contacts received high-risk IUU assessments.

Information on the 16 vessels has been referred to the relevant national authorities for further assessment and possible enforcement action. FFA said the vessels of interest were associated with IUU fishing and maritime crime.

The surveillance effort involved aerial and surface patrols across the exclusive economic zones of 11 FFA members and adjacent high-seas areas. The operation brought together fisheries, maritime, police and defence personnel, supported by Australia, France, New Zealand and the United States, as well as regional and technology partners.

FFA Director-General Noan David Pakop said the results demonstrated the growing ability of Pacific countries to use intelligence, satellite technology and coordinated patrols to protect the region’s tuna resources.

For Tonga and other Pacific island countries, the operation highlights the importance of regional cooperation in protecting fisheries resources that underpin economies, food security and government revenue.

The operation also involved 25 personnel seconded from participating FFA members to the Regional Fisheries Surveillance Centre in Honiara, strengthening national and regional surveillance skills.

FFA said Operation Island Chief forms part of its continuing programme of regional monitoring, control and surveillance operations aimed at improving compliance with fisheries rules and protecting Pacific fisheries.
