Celebrating Progress in Science and Collaboration for Sustainable Fisheries
In 2025, ISSF and our partners continued to make meaningful progress toward more sustainable tuna fisheries — from expanded transparency tools and evidence of improving stock health to stronger management practices and cross-sector collaboration. These highlights capture the stories that resonated most with our audiences and reflect gains toward science-based, accountable progress for global tuna fisheries.
1. ISSF Expands Tuna Vessel Best Practices Tracked on VOSI
Enhanced transparency to accelerate adoption of science-based practices
ISSF broadened the range of best practices tracked and verified on its Vessels in Other Sustainability Initiatives (VOSI) tool, offering clearer insight into how vessels are performing against sustainability expectations. The update, which also included a user-friendly redesign, strengthens accountability and supports more comprehensive implementation of improved fishing practices across the global tuna fleet.

2. A Consistently Strong Indicator: 87% of Global Tuna Catch Comes From Healthy Stocks
Sustained progress driven by long-term RFMO management improvements
ISSF’s analysis reaffirms a positive, stable trend: the vast majority of global tuna catch continues to come from stocks at healthy abundance levels. This figure has held steady in recent years, and its persistence is meaningful — reflecting durable gains from science-based management and sustained action by RFMOs and stakeholders across the supply chain. It remains a key indicator of where collective efforts are working and where continued vigilance is needed. Learn more.
