To promote transparency in fishing, ISSF works with regional organizations and data sources to provide information about vessels and their practices. We maintain four searchable public tuna vessel lists for sustainable fishing stakeholders, including seafood buyers.
ProActive Vessel Register (PVR)
Vessels register on the PVR to show how they are following best practices that support sustainable tuna fisheries.
Seafood buyers can consult the PVR to fulfill their sustainable seafood sourcing policy requirements.
Vessels in Other Sustainability Initiatives (VOSI)
The VOSI is the only publicly available list of tuna fishing vessels that are part of a Fishery Improvement Project or fishing in an MSC-certified fishery.
This list is a tuna sourcing tool for seafood companies.
Record of Large-Scale Purse Seine Vessels (LSPSR)
The LSPSR lists all large scale purse seine vessels fishing for tuna.
This consolidated global view of the large-scale purse seine fleet supports ISSF and RFMO efforts to prevent overfishing.
