Participating Companies

We believe it’s important to work with all stakeholders — and tuna processors, traders, and/or marketers are integral to improving the sustainability of the world’s tuna resources.

Companies that participate in ISSF are members of the International Seafood Sustainability Association (ISSA). Membership in ISSA is voluntary and is contingent upon compliance with ISSF conservation measures and standards of practice. We publish audit reports for each participating company.

All companies work with the Foundation to advocate for improved fishery management, fund scientific advancements through research and expert analysis, and take direct action to encourage the adoption of responsible fishing practices – all while committing to a suite of conservation measures aimed at improving the long-term health of global tuna fisheries.
