Forever Fish

At M&S, we’ve had a sustainable fish and seafood sourcing policy in place for more than 20 years. That means we can trace all our fish – from fishcakes to fresh cod and tinned tuna – back to where it’s caught. We only work with fisheries who adhere to our strict sourcing policy and endeavour to improve their sustainability. Plus, we only source from farmed fish producers who help us to deliver our high animal welfare standards. We also work alongside fisheries around the world to ensure best practices for crew welfare, promote responsible fisheries management and advocate for policy reform to protect our precious oceans. On top of that, we're proud to say we're the only national retailer selling 100% pole and line-caught skipjack tuna.

Where we source our fish

Not only does our fish taste great, but it’s responsibly sourced from trusted fisheries, so it’s a dinner you can feel good about. Meet the experts supplying our salmon, haddock and more.

Salmon

Sourced from the crystal-clear waters surrounding Scotland's west coast, Orkney and Shetland Islands, just one portion of M&S Caledonian Gold salmon provides your full recommended weekly omega-3 intake. The salmon are reared in specially selected marine sites with faster-flowing waters, allowing them to swim harder, ensuring the fish are fitter and stronger. All our Scottish salmon is RSPCA Assured, meaning they’re raised to higher welfare standards with plenty of space to swim.

Smoked haddock

We’ve been sourcing the best quality Scottish smoked haddock from the same Scottish supplier, Lunar, for over 20 years to ensure you get the perfect fillet every time. This fourth-generation family-owned fishing business based in Peterhead, Aberdeenshire catches their haddock in the North Sea and is hand-filleted by locals within three miles of the harbour.

Trout

Our trout is farmed by a small Scottish Family farm with small farms in Argyll, Loch Tay and Skye. They have their own bespoke breeding programme, which means they raise the healthiest, strongest, and tastiest trout specifically adapted to the Scottish marine environment.

The freshest Scottish seafood

M&S is one of the largest supporters of the Scottish fishing industry. We’ve worked with Lunar, a fourth-generation family fishing company, for over 20 years, to bring top-quality Scottish mackerel, herring and haddock to our stores. “M&S has high-quality standards and champions Scottish fish. This works for us, because the market’s on our doorstep,” says Iain from Lunar Seafoods in Aberdeenshire. Iain and his team ensure only the freshest fish is landed for us. It is hand-filleted by locals within three miles of the harbour. All our Scottish haddock is Marine Stewardship Council-approved and Lunar's boats also maintain high standards of crew welfare onboard the vessels.

The RSPCA is the UK’s largest animal welfare charity, operating throughout England and Wales advocating for animal welfare, rehoming animals, and conducting investigations and securing convictions for abuse of animals. The SSPCA and USPCA fulfil a similar role in Scotland and Northern Ireland, and all work together to advocate for animal welfare across the UK. In addition to this work, the RSPCA develops welfare standards for farm animals, which outline best practice in care and welfare, to ensure farm animals have a better quality of life. These standards are world renowned and used by many welfare organisations worldwide. In the UK, these standards are applied through the RSPCA’s farm assurance scheme, RSPCA Assured. RSPCA Assured works across all of the UK to support farmers who wish to raise their animals to higher welfare standards.
