Pollack (Pollachius pollachius)
The pollack has three dorsal fins on its back and two anal fins on its belly, similarly to cod, but they have no barbel under their chins, and their bottom lip protrudes past their top lip. Their colour is variable depending on habitat, but they usually have a dark greenish brown back that fades to lighter coloured sides with a metallic sheen. Their dark brown lateral line bends sharply around their pectoral fin behind their heads.
Pollack form schools around rocks and rough ground, where they prey on other fish. They spawn in late winter and early spring, and juvenile pollack live close inshore, often among kelp. The pollack is very popular fish for recreational sea anglers that can be caught throughout the summer and autumn.
