Vessels of all gear types that have made certain sustainability commitments beyond those reflected on ISSF’s ProActive Vessel Register (PVR) are eligible to be listed on our Vessels in Other Sustainability Initiatives (VOSI) list.

The VOSI list is a tool for seafood companies that want to source tuna from vessels committed to sustainable fishing practices.
