About Pollock
Pollock is the common name used for either of the two species of North Atlantic marine fish in the genus Pollachius. Pollachius pollachius is referred to as pollock in both North America and the United Kingdom, while Pollachius virens today is usually known as coley in the British Isles. Both species can grow to 105 centimetres (3.44 ft) and can weigh up to 21 kilograms (46 lb).
