Vessels of all gear types fishing in a Marine Stewardship Council (MSC)-certified tuna fishery, participating in a publicly listed and third-party-verified tuna Fishery Improvement Project (FIP), or both are eligible to be listed on VOSI.

Our Vessels in Other Sustainability Initiatives (VOSI) list helps seafood companies to find tuna vessels that have made important public commitments to sustainable fishing through the MSC or a FIP.
