The World Needs a New Approach to Tuna

Better Data for Better Decisions

WWF examined the status of 23 tuna stocks most often caught and found that for three of the tuna stocks, the spawning stock biomass (SSB) levels could not be determined; in six cases it was not possible to determine the percentage of current spawning biomass in relation to unfished biomass. Collectively these are known as “data deficient” fisheries. This is simply too much missing information for science-based policymaking.

How does WWF address tuna stock health and sustainability?

WWF’S global tuna strategy aims to bring the exploitation of tuna for food and as a source of revenue by industrial and artisanal fisheries into balance with their fundamental role in ecosystem maintenance. WWF’s approach is focused on ensuring that all tuna stocks are rebuilt by 2040 to optimal biomass levels, defined as a spawning stock biomass of at least 40%, and bycatch of endangered, threatened and protected species is eliminated.
