Status of the Stocks Reports

Every year, as a tool for RFMO policymakers and fisheries managers, we produce a Status of the Stocks report that scientifically assesses 23 commercial tuna stocks worldwide based on the most recent abundance and fishing mortality data.

The comprehensive report indicates how a stock is being managed — including through reference points and harvest control rules — and whether it is at "healthy" levels, overfished, or in danger of becoming overfished. Status of the Stocks also examines the environmental impact of tuna fishing on other marine species, or “bycatch.”

Marine Stewardship Council Certification

The Marine Stewardship Council (MSC) is a globally recognized sustainable-seafood program. Helping tuna fisheries to meet sustainability criteria and achieve MSC certification — without conditions — continues to be ISSF's ultimate objective. All of ISSF's work, including its tools and programs, support MSC certification and fishery improvement more broadly.

ISSF publishes a report that evaluates and "scores" tuna stocks against MSC principles focused on stock status and management effectiveness (Principle 1 and Principle 3, respectively). ISSF also has published a preliminary report that pre-assesses tuna fisheries based on MSC Principle 2 (environmental impact).

SUMMARY OF SUSTAINABLE FISH STOCKS (MSC Principle 1 Averages) February 2013 through December 2017

The P1 averages in the graph below were calculated using the average scores of all stocks for each performance indicator.

*Some changes are due to consolidation and adjustments to the MSC Standards
**In 2017 MSC issued more clear (and stricter) guidance on how to score HCRs.
