The fish that we eat impacts the health of our ocean and marine life that call it home. Our Good Fish Guide helps you to make informed choices about the seafood on your plate, using a simple traffic light system - Red means Fish to Avoid and Green is a Good Choice.

Our seas face a wide range of threats, including climate change, pollution, habitat loss and biodiversity loss.

The UN has named unsustainable fishing as the greatest driver of marine biodiversity loss in the world. 90% of global fish stocks are fully or overexploited.

We've developed a tool which allows you to browse, search and explore seafood species which are clearly rated by their sustainability score - using rigorously researched ratings.
