Lavaret

Description

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 snout is short and tapered,a fact that distinguishes this species from the two other North European Coregonus species,vendace (Coregonus albula) and the introduced peled (Coregonus peled).The former has a protuberant lower jaw while in the latter,the jaws are equal in length.The back is bluish green or brownish,the flanks silvery and the belly white.The fins are dark grey.This fish seldom grows more than 55 cm (22 in) long or exceeds 2 kg (4.4 lb) in weight
