The Whitefish (lat. Coregonus lavaretus) is a species of freshwater whitefish, in the family Salmonidae. There is much variation among the European whitefish forms, but in general they have a tapered body, a slightly protruding upper jaw and a fleshy dorsal fin that is typical of the salmon family.
The whitefish has a typical salmonid body shape and is silvery on the sides and underside with a dark blue, bluish green or brownish back. The fins are dark grey. The whitefish mostly feed on benthic invertebrates or zooplankton. Big fish also eat fish fry and take insects off the surface of the water.
The Whitefish seldom grows more than 55 cm (22 in) long or exceeds 2 kg (4.4 lb) in weight.
