Description
The blaufelchen is a slender whitefish of the family Salmonidae reaching about 50 cm. The streamlined, silvery body has a blue-grey back and an adipose fin between the dorsal and tail fins, characteristic of the salmonids. The species is endemic to Lake Constance, where as a pelagic whitefish it lives in schools in the open water and spawns on the bottom or in midwater. In open water it filters zooplankton, mainly water fleas and copepods. The whitefish form a taxonomically difficult complex, with many lakes holding their own, often endemic forms that spawn in different seasons and at different depths. With its fine flesh it is locally a valued commercial and sport fish.
