Why They Matter
Tuna underpin the ecosystems and economies where they live. They are an apex predator and consume a wide variety of other fish, from squid to herring to sardines. This keeps the populations of other species healthy and balanced. Tuna are also among the most commercially valuable fish on the planet and support artisanal and industrial fishing alike. They are a plentiful and affordable source of protein for people around the world. Driven by this demand and high prices in sushi markets, fishers use even more refined techniques to catch tuna. And some species are disappearing as a result.
Although tuna do provide food and livelihoods for people, they are more than just seafood. Tuna are a top predator in the marine food chain, maintaining a balance in the ocean environment.
