Our measures reflect conservation needs in tuna fisheries worldwide that ISSF has identified together with our Board of Directors, Scientific Advisory Committee, Environmental Stakeholder Committee, and ISSF participating companies.
We partner with third-party auditor MRAG Americas to develop audit protocols for each measure and then track compliance and results for participating companies and ProActive Vessel Register (PVR)-listed vessels.
Each ISSF participating company commits to comply with all applicable ISSF conservation measures, which address a range of policy, purchasing, and operational issues — from vessel transactions to product labeling.
The ISSF Data Check Company designation has more limited financial and auditing requirements than ISSF Participating Company membership.
Through a rigorous compliance and audit process led by MRAG Americas, an independent auditing firm with fisheries expertise, ISSF holds tuna and other seafood companies to high standards for transparency and accountability. We publish participating company audit reports and Data Check company audit reports on this site.
We regularly review and update our conservation measures — or establish additional measures — based on the latest fisheries research, technology resources, and emerging or urgent conservation and/or management needs.
