We’ve become a little bit set in our ways over the years with our ‘go-to’ fish choices; cod, haddock, tuna, salmon and warm-water prawns, but this has really jeopardised their sustainability. There are many alternative species available for us to try that have been farmed or caught responsibly, hake, corley, rainbow trout, mackerel and rope grown mussels are all great choices of sustainable fish in the UK.
