KOTKA MARETARIUM
Whitefish Coregonus lavaretus
Whitefish are a diverse species with a multitude of subspecies in various environments. This silvery lake fish is a relative of salmon; their smaller specimens greatly favour vendace. Whitefish differ from vendace, in that their lower jaw is shorter than their upper jaw. Depending on the subspecies, whitefish eat either small bottom-dwelling animals or small crustaceans. Whitefish spawn in autumn, in coastal regions, streams, lakes and rivers, the location varying according to subspecies. Whitefish are at home all over Finland, in cool and oxygen rich water. They can exceed 60 centimetres in length and weigh up to 12 kilograms.
