Pollack are a member of the cod family and can be found in British waters. Adults and juveniles differ in colour, with adults being generally dark green along their back with silvery sides and bellies whereas juveniles tend to be more darkly coloured – either green or brown or sometimes beautiful crimson and gold. They are a predator, hunting either alone or in small groups or shoals and eating other fish such as sand eels, herring and whiting.
