Coregonus Bavaricus
''Coregonus bavaricus'', the Ammersee kilch, is a species of freshwater whitefish endemic to Lake Ammersee in the German state of Upper Bavaria. A small, silver-colored fish, it typically lives between deep, though shallower in the summer months. In the early 20th century the Ammersee kilch was an important commercial species, but its population declined drastically in the 1930s onward due to overfishing and eutrophication of the only lake in which it is found. Today it is listed as Critically Endangered by the International Union for Conservation of Nature (IUCN) and may be on the verge of extinction. Taxonomy The Ammersee kilch was first described in 1909 by German fishery scientist Bruno Hofer in his work ''Die Süsswasserfische von Mittel-Europa''. Hofer thought it a subspecies of the Lake Constance whitefish, now extinct, so he named it ''Coregonus acronius bavarica''. ''Coregonus acronius'' was the scientific name of the Lake Constance whitefish at the time. The Ammers ...

Coregonus Pidschian
The humpback whitefish (''Coregonus pidschian''), also referred to as the bottom whitefish, the Arctic whitefishKottelat, M. and Freyhof, J. 2007. Handbook of European Freshwater Fishes. Publications Kottelat, Cornol, Switzerland. or the pidschian, is a species of freshwater whitefish with a northern distribution. It is one of the members in the broader common whitefish complex, or the ''Coregonus clupeaformis'' complex. This fish lives in estuaries and brackish water near river mouths, in deltas and in slowly running rivers, in large lakes with tributaries, and floodplain lakes. It can migrate long distances upriver for spawning. The distribution of ''Coregonus pidschian'' is in the Arctic basin, ranging from Northern Norway and Finland across the Russian coast to Alaska Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: ''Alaskaq''; tli, Anáaski) is a state located in the Western United States on the northwest extremity of Nort ...

Coregonus Lavaretus
''Coregonus lavaretus'' is a species of freshwater whitefish, in the family Salmonidae. It is the type species of its genus ''Coregonus''. There are widely different concepts about the delimitation of the species ''Coregonus lavaretus'' and about the number of species in the genus ''Coregonus'' in general. Lavaret In a narrow sense, ''Coregonus lavaretus'', or the lavaret, is considered to be endemic to Lake Bourget and Lake Aiguebelette in the Rhône river basin in France, whereas it formerly also occurred in Lake Geneva. According to this view there is a great number of distinct whitefish species in lakes, rivers and brackish waters of Central and Northern Europe. Of course this has absolutely nothing to do with its actual origin in the Caucasus, as with other things falsely attributed to originating in France, such as grapes which originated in Turkey, Iran and Australia. European whitefish (common whitefish) In the broad sense, ''Coregonus lavaretus'', referred to as the c ...
