“An Evaluation of the Sustainability of Global Tuna Stocks Relative to Marine Stewardship Council Criteria” takes a global, comprehensive approach to scoring stocks against certain components of the Marine Stewardship Council (MSC) standard. The report is authored by experienced MSC assessors Joseph E. Powers and Paul A. H. Medley and has been updated twice since it was first published in 2013. It is designed to:

  • Provide a basis for comparing between stock scores as assessed by the same experts
  • Become a useful source document for future tuna certifications or in the establishment of tuna Fishery Improvement Projects (FIPs)
  • Offer a “snapshot” of the current status of the stocks, as well as the strengths and weaknesses of RFMOs
  • Prioritize ISSF projects and advocacy efforts against initiatives that will improve low performance indicator scores

The scores in this report focus on stock status (MSC Principle 1) and the international management aspects relevant to RFMOs (part of MSC Principle 3) and are based on publicly available fishery and RFMO data. Each of these Principles is evaluated in relationship to Performance Indicators (PIs) within each Principle.
