Give popular fish species a break, and give them time to recover from overfishing, by swapping to different stocks and species - delicious, nutritious and just as easy to prepare!

What fish do you want to swap?

The Sustainable Fish City: Top Ten Swaps have been devised with advice from expert organisations that contribute to the Sustainable Fish City working party. See the about page for more information.

Overall, UK consumers need to halve the amount of meat and dairy in our diets to keep climate change within 1.5 degrees of warming. The remainder should come from agro-ecologial production or sustainable fishing. There's more about eating fish in a climate and nature emergency on our dedicated page.

Sustain is calling for much better government policies for managing our marine ecosystems, including investing in better data, more equitable sharing of fishing rights, and using public procurement better to support sustainable diets and producers. 

The Sustainable Fish Cities project is calling for fish-serving businesses in the UK to pledge to sell only fish that is verifiably sustainable. Is your favourite restaurant of caterer signed up?
