Buying sustainable tuna at a grocery store or sushi restaurant

Our guide breaks down how to buy sustainable tuna in 2025.

Dear all,


Over the past year, we’ve made a concerted effort to write articles that speak directly to everyday, curious consumers. Our goal is that when people search for seafood sustainability information online, they find clear, science-based answers.


Our latest post focuses on tuna, building on the success of last year’s guide to shrimp. We cover the major tuna species, how they’re caught, and what that means for sustainability—all in a format designed to be accessible and shareable.


We hope this guide is useful in your work—whether that means pointing people toward reliable information or incorporating it into outreach or marketing materials.

 

An overview of tuna and its sustainability in 2025

 

All the best,

Ray Hilborn
