The ProActive Vessel Register, or PVR, is one of the public vessel lists that ISSF provides to foster transparency in tuna fishing. This list connects responsible fishers and seafood companies. Fishing vessels can register on the PVR to show how they are following practices that support sustainable tuna fisheries.
The PVR tracks detailed vessel information, including with respect to certain fishing activities as well as compliance with ISSF Conservation Measures. MRAG Americas, a third-party independent auditor, audits all vessels that join the PVR. Purse-seine vessels that register on the PVR also need to ensure that their skippers complete one of the following:
- Review this purse-seine skippers guidebook, which is available as a downloadable PDF (multiple languages) or online (English only) at issfguidebooks.org. The guidebooks contain information on bycatch handling and mitigation, non-entangling and biodegradable FADs, mitigating tuna purse seine fishing’s ecosystem impacts, RFMO requirements, and other useful information about fishing sustainably OR
- Attend an in-person and/or online ISSF skippers workshop on sustainable fishing practices OR
- Attend an in-person skippers workshop conducted by a trainer that has been accredited by ISSF to conduct these workshops OR
- View an ISSF skippers workshop video online
If you skipper a purse-seine vessel on the PVR, ISSF’s PVR list webpage lists the actions that the vessel has committed to undertake as part of joining the PVR. These actions, known as ISSF Conservation Measures, are detailed in the following section.
