Responsible Seafood

Ever wondered where the fish you eat comes from? Or if you are choosing the right ones?

The future of the fish supper is no longer guaranteed. Many fish stocks are in a state of serious decline, with overfishing a great threat to marine wildlife and habitats. With 90% of world fish stocks fully or over-exploited from fishing, plus pressure from climate change and pollution, we’re moving into dangerous waters when it comes to the fish of the future.

We are leading the way on changing habits. You can help reduce the strain on certain species by demanding that the fish you eat comes from sustainably managed stocks and is caught or farmed in a way that causes minimal damage to the marine environment and other wildlife. Doing the right thing is easier than you think. Check out our Good Fish Guide and download the free app.
