Our “snapshots” identify best practices that Regional Fisheries Management Organizations (RFMOs) should follow to manage tuna fisheries sustainably.

In detailed tables, the snapshots compare tuna RFMO progress in implementing the practices.

For a high-level comparison across the five RFMOs, see our Tuna RFMO Best Practice Performance “scorecard” below. We also publish companion “best-practices reports” on these topics and “RFMO progress” infographics.
