The State of Global Tuna Sustainability in 2026: Momentum, Modernization, and the Path Ahead
As we begin 2026, there is real reason for optimism about the state of global tuna fisheries. After more than a decade of focused work by scientists, managers, industry, and the NGO community — including ISSF— the foundations of sustainable tuna management are stronger than ever. Most of the world’s tuna catch comes from stocks at healthy levels, and a growing share comes from fisheries managed under modern, science-based frameworks.
This progress did not happen by chance. It reflects sustained investment in science, improved international cooperation, and a shared recognition that long-term sustainability is not only an environmental imperative but also a prerequisite for resilient seafood supply chains and coastal communities and fishing livelihoods.
At the same time, 2026 is a pivotal year. The gains we have made must now be implemented and globally extended. Success will depend on whether tuna regional fisheries management organizations (RFMOs) can continue to make the necessary improvements to transition to fully modern fisheries governance.

ISSF RFMO Priorities
Each year, we identify priority actions for tropical-tuna RFMOs to take to improve fishery sustainability in their regions. To shape RFMO discussion and decision-making, ISSF’s science and advocacy experts have outlined their concerns and advice below. Our position statements — which we disseminate ahead of RFMO annual meetings and special sessions — explore and expand on these priority topics.
ISSF participating seafood companies also reinforce ISSF recommendations through their own direct advocacy to RFMOs. Our Web feature story maps their influence network, including MSC-certified and -assessed fisheries and tuna fishery improvement projects (FIPs), in IATTC, ICCAT, IOTC, and WCPFC.

PVR & VOSI Participation Continues to Expand
Participation in ISSF’s ProActive Vessel Register (PVR) and Vessels in other Sustainability Initiatives (VOSI) public vessels lists has continued to grow steadily since each tool’s launch, reflecting broader uptake of transparency and accountability tools across the tuna sector.
The accompanying graphics show growth across vessel types through 2025, highlighting increased engagement with ISSF’s science-based frameworks. This expanded participation strengthens the information available to the NGO community, market actors, and other stakeholders working to advance effective, responsible tuna fisheries worldwide.
