Document: The ISSF Analysis of Tuna Fisheries Against Marine Stewardship Council (MSC) Performance Indicators (PIs)


ISSF regularly assesses the status of global tuna stocks according to the methodology developed by the Marine Stewardship Council (MSC), one of the world’s most widely recognized certification schemes for sustainable seafood. The result is a recurring report titled An Evaluation of the Sustainability of Global Tuna Stocks Relative to Marine Stewardship Council Criteria.

The report, although not an official MSC assessment, is written by independent and experienced MSC assessors Paul Medley and Joseph Powers and applies a consistent methodology across 19 major tuna stocks and four tuna Regional Fishery Management Organizations. The aim is to evaluate the sustainability of these stocks and RFMO management systems applying the MSC standards.

In addition to serving as a resource for an interested public, this report also helps ISSF focus its resources on addressing the roadblocks to certification for tuna fisheries, which ultimately means the challenges that prevent us from declaring all tuna sustainable.

This document is a visual snapshot of the technical report.
