The people behind GSA

Global Seafood Alliance employees come from a variety of backgrounds and disciplines, but we all share a love of our waterways, our oceans and our seafood. We believe that proof of responsible performance – from fishing vessels to fish farms – is essential to build consumer trust in seafood.

Our Team

The GSA team is collaborative, dedicated and focused on creating a better future for us and for our planet through responsible seafood practices. Our shared vision is a world that embraces the role of responsible seafood in meeting global nutrition needs.
