There’s no need to master new recipes – just swap in sustainable alternatives to your usual weeknight meals. Simple changes like this can make a big difference without sacrificing flavour or convenience.

Did you know that most of the seafood we eat in the UK actually comes from what we call the big five: cod, haddock, salmon, tuna, and prawns? This concentrated demand puts a lot of strain on wild populations, leading to unsustainable fishing and farming practices.

By mixing things up and trying other types of whitefish, you can help reduce pressure on over-exploited species, all while still enjoying delicious, affordable options.

Relying on just five species can also get pretty dull, so why not explore some of the other sustainably caught or farmed options available:

Basa is a mild-flavoured, affordable whitefish that’s widely available in UK supermarkets. It’s a great budget-friendly alternative to haddock and cod.

For the best option, choose basa certified by the Aquaculture Stewardship Council (ASC), GLOBALG.A.P., or Global Seafood Alliance Best Aquaculture Practices. Check the Good Fish Guide for more information.

Frozen Alaska pollock is a brilliant, versatile option for all sorts of dishes. It’s fisheries are well managed, making it an affordable and sustainable choice.

Whiting is a delicate, mild-flavoured whitefish that’s often overlooked, but is actually one of the more affordable choices in our supermarkets. Perfect for fish pies, casseroles, or even fish and chips, it’s a fantastic like-for-like swap for cod.

Choose MSC-certified whiting for a green-rated option on the Good Fish Guide.
