M&S has launched a new interactive map to detail where the seafood is caught and farmed.
The map includes any seafood ingredients in sandwiches, salads, and ready meals. There is a total of 47 different species on the map.
There are 16 species that come from UK waters including herring, monkfish, plaice, lemon sole, haddock, brill, hake and mackerel. Species such as rainbow trout, salmon, blue mussels and rock oysters are all farmed in the UK.
Hannah Macintyre, M&S marine biologist, said: “We know how much our customers care about responsible fishing. We wanted to share with them all the data we have on where our fish comes from and how it is caught. Transparency is an important part of the trust that our customers and stakeholders put in us, that’s why we’ve published this smart tool which lays bare our whole fish supply chain, wherever it is in the world and however it is fished or farmed.”
