Ethical guide to fish

Last year it was reported that the anchovy is now a "fish to avoid" due to low stocks. In the perfect catch, Allegra McEvedy offers a definitive guide to which species of fish are safe to buy.

She recommends gurnard, black bream, coley (saithe), flounder and dab, as well as the more familiar mackerel, herring, sardines and pilchards. She also offers a recipe for a sustainable fish stew.
