Document: ISSF 2026-02: Benchmarking Tuna RFMO At-Sea Transshipment Measures Against the 2022 FAO Voluntary Guidelines: A Comprehensive Analysis


This analysis benchmarks transshipment measures in the five tuna RFMOs against the 2022 FAO Voluntary Guidelines for Transshipment.

Results show no RFMO currently fully implements these guidelines. ICCAT and CCSBT demonstrate the strongest levels of implementation. IATTC, IOTC and WCPFC show solid implementation in some areas, and each have varying degrees of improvement needs.

Overall, for all tuna RFMOs, gaps exist in implementing the guidelines in the areas of risk-based approaches, documentation and reporting, and verification and monitoring. To support continuous improvement and to assist RFMOs in their efforts towards full implementation of the FAO Guidelines, this analysis informed the development of implementation checklists for all tuna RFMOs (Annex 1), and the identification of those data fields that would bring existing RFMO transshipment declarations more in alignment with the FAO Guidelines (Annex 2).
