A familiar eating fish, the Atlantic Cod, Gadus morhua, is a stocky. distinctive fish with a long chin barbel. It is greenish or sandy-brown. However, those that move inshore in summer and live in the kelp often adopt a dark red hue. Juvenile cod which are common in shallow water in the summer tend to have a pale, mottled appearance (see next photograph).
Found all around the UK from the shoreline right down to 600m, it feeds on crustaceans, brittle stars, worms and fish. Growing to around 45kg, they are a target for a great deal of commercial fishing which has reduced their population to a mere shadow of what it used to be. Medium size fish are usually referred to as codling.
