Tuna processors, marketers, and traders can become ISSF Data Check Companies to show their commitment to improve the long-term health of tuna fisheries.

- Conservation Measure 1.1 – Tuna RFMO Authorized Vessel Record
- Conservation Measure 2.2 – Quarterly Data Submission to RFMO
- Conservation Measure 4.1 – Unique Vessel Identifiers – IMO
- Conservation Measure 4.2 – Purse Seine Unique Vessel Identifiers
- Conservation Measure 5.1 – Illegal, Unreported and Unregulated (IUU Fishing)
Global Tuna-Vessel Lists
To promote transparency in the seafood industry and prevent illegal fishing, ISSF maintains four searchable, global tuna-vessel lists, including to track Fishery Improvement Project (FIP) participation and IMO or UVI numbers.
