Like the ProActive Vessel Register (PVR), ISSF’s Vessels in Other Sustainability Initiatives (VOSI) list is a transparency tool for the public, including seafood companies that want to understand which tuna vessels have made public commitments to sustainable fishing beyond the commitments reflected on the PVR.
Vessels in MSC-Certified Fisheries or FIPs
The VOSI — introduced in 2020, our newest public, verified vessel list — enables users to find vessels that are fishing in a Marine Stewardship Council (MSC)-certified tuna fishery, participating in a tuna Fishery Improvement Project (FIP), or both. Vessels in transition between a FIP and MSC certification are also eligible to be listed on the VOSI. The list is verified through a third-party audit process.
Each VOSI record includes vessel UVI number, vessel flag, and vessel type, and other details — including whether the vessel also is listed on our PVR and/or Record of Large-Scale Purse Seine Vessels (LSPSR). Vessel information can be downloaded in .csv format.
VOSI Application Process
MSC-Certified Tuna Fisheries
Find out which tuna fisheries worldwide have met the Marine Stewardship Council’s stringent sustainability standards and which are currently undergoing a Full Assessment.
VOSI Vessel List
Browse, search, and sort vessel data in the VOSI, and find out what vessels are also on the PVR and LSPSR. You can also download a CSV copy of the whole VOSI list to your desktop.
Vessels of all gear types that are operating in Marine Stewardship Council (MSC)-certified fisheries, participating in Fishery Improvement Projects (FIPs), or both can apply to be listed on ISSF’s Vessels in Other Sustainability Initiatives (VOSI) public list. Vessels from fisheries that were in a FIP listed on www.fisheryprogress.org and have moved on to an MSC Full Assessment are also eligible.
MSC certification is a science-based global standard in sustainable fishing. Helping all tuna fisheries to become capable of realizing MSC’s certification standards “without conditions” is ISSF’s long-time guiding objective.
A Fishery Improvement Project (FIP) is a multi-stakeholder effort to address environmental challenges in a fishery, using the power of the private sector to incentivize positive changes toward sustainability.
Using the VOSI
You can search and filter the VOSI list by vessel name, UVI number, UVI type, vessel flag, vessel type, and other categories.
- The VOSI shows when a vessel also is registered on ISSF’s Record of Large-Scale Purse Seine Vessels and/or ProActive Vessel Register; it also shows the vessel’s historical PVR status in complying with defined best practices.
- If a vessel operates in an MSC-certified fishery, or in a fishery in transition to MSC certification, the VOSI provides the fishery name (linked to an MSC fishery description page) and certification dates.
- If a vessel participates in a FIP, the VOSI provides the FIP name (linked to a FisheryProgress.org FIP profile page) and dates.
You will see these symbols in vessel records in the VOSI:
|Green checkmark means the vessel appears in another ISSF public vessel list and/or participates in an MSC-certified fishery, a fishery in transition to MSC certification, and/or a FIP|
|Information symbol: When clicked on, shows a vessel’s national registration number, radio call sign, RFMO numbers, and dimensions|
|PVR status symbol: When clicked on, shows current and historical information in the PVR for that vessel|
VOSI records can be downloaded in CSV format. Note that when a vessel is participating in more than one initiative, it will appear in multiple rows (one per initiative) in the downloaded file.
Audits of vessels listed in the VOSI are carried out remotely and organized on two levels to ensure auditing goals are achieved efficiently and effectively:
- All vessels applying to be recognized undergo an initial Level 1 audit as part of the listing process.
- Level 2 audits are conducted on an appropriate sample of vessels to assist in verifying information provided to show conformance with, and/or active participation in, FIPs and/or MSC-certified fishery(ies).
All vessels will receive either a level 1 or level 2 audit on an annual basis.
Vessel owners interested in having their vessels also listed in the ProActive Vessel Register (PVR) must complete the separate PVR application process.
