One tends to think of fish being from the sea but, of course, there are many delicious species that grace British and foreign rivers and lakes. Several are now farmed, increasing their sustainability.

The skin should be shiny and slippery or even slimy, the flesh firm and moist, not wet. On whole fish, the eyes should be prominent and bright.

Storage: Unless frozen, eat on day of purchase, or store well-wrapped in the bottom of the refrigerator for up to 24 hours. Fresh fish can be frozen, gutted, whole or in fillets for upto 2 months.
