The Good Fish Guide has all the advice you need to make sure your fish dish is sustainable.

Why should I avoid unsustainable seafood?

The fish that we eat impacts the health of our ocean and the marine life that call it home.

The UN has named unsustainable fishing as the greatest driver of marine biodiversity loss in the world.

Some fish are as endangered as the Bengal tiger, yet they're still finding their way onto our plates.

Unsustainable seafood can have many different impacts, from overfishing in the wild to excessive chemical usage in fish farms.

How can choosing sustainable seafood help?

We believe there's a firm place for responsible, well-managed fishing and aquaculture in our vision for healthy seas.

Over 2 billion people around the world depend on seafood as their primary source of protein. With an ever-growing population, there is increasing pressure on our ocean to supply us with food.

It's critical that we meet our future protein needs whilst ensuring the health, diversity and productivity of our marine environment.

There's also increasing evidence that some forms of seafood can provide an important source of low-carbon protein, which is crucial for our changing climate.

When consumers choose sustainable seafood, it encourages supermarkets and restaurants to demand it from their suppliers.

This demand can reward fishers and fish farmers who adopt sustainable practices. It also encourages governments to improve management.

By choosing only sustainable seafood, we can help minimise damage to vulnerable habitats and species.

Wild-caught and farmed seafood supports the social and economic prosperity of many coastal communities and countries, including in the UK. Over time, we've seen that the market demand for more sustainable seafood is encouraging real improvements in the management and operation of fishing and aquaculture.

Where does the Good Fish Guide come in?

The Good Fish Guide is your simple guide to find out the environmental impact of the seafood you buy. It's based on which species it is, where it’s been caught or farmed, and how.

It uses a simple traffic light system. Green-rated fish are from the most sustainable fisheries and farms, caught and produced in an environmentally-friendly way. Red-rated fish are the least sustainable options as a result of overfishing, habitat damage or other unsustainable practices.
