Scaling Electronic Monitoring in Tuna Fisheries
As discussions at the Our Ocean Conference highlight the role of technology in sustainable fisheries, electronic monitoring continues to gain momentum across tuna fisheries. Once limited to pilot projects, EM is increasingly being incorporated into fisheries monitoring programs, supported by regional standards, technological advances, and growing operational experience.
As implementation expands, attention is increasingly focused on how electronic monitoring can support fisheries data collection, compliance, and transparency across tuna fisheries.

IUU Fishing, Facts, and Fisheries Management
Setting the Record Straight on IUU Fishing in the Western and Central Pacific
Illegal, unreported, and unregulated (IUU) fishing remains a significant concern in global fisheries, including in the Western and Central Pacific Ocean. In a guest blog for ISSF, Dr. John Hampton examines available data and fisheries management information to provide context on IUU fishing estimates and their interpretation. The blog explores how IUU fishing is assessed, the role of regional management measures, and why accurate use of fisheries data is important to informed discussions about tuna sustainability.

Transparency Tools for Tuna Fisheries
Accessible Information on Vessel Practices and Sustainability Initiatives
ISSF’s ProActive Vessel Register (PVR) and Vessels in Other Sustainability Initiatives (VOSI) help support transparency across global tuna fisheries by providing public access to independently audited vessel-level sustainability information.
At the end of 2025, the PVR listed an all-time-high 1,839 vessels — representing approximately 83% of large-scale tropical tuna purse-seine fishing vessel hold capacity globally. VOSI also surpassed 1,200 vessel registrations, expanding visibility into vessel best practices across fleets. The PVR includes vessels audited on their compliance with select sustainability measures directly linked to ISSF conservation measures. VOSI complements the PVR by providing visibility into additional vessel practices and sustainability initiatives beyond compliance requirements reflected on the PVR.
Together, these tools help provide stakeholders with verified, accessible information on vessel-level sustainability practices across global tuna fisheries.
