The Ammersee kilch (Coregonus bavaricus) 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 60–85 m (197–279 ft) 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 the Conservation of Nature (IUCN) and may be on the verge of extinction.
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 Ammersee kilch was reclassified as its own species in 1997 by Swiss ichthyologist Maurice Kottelat in his piece "European freshwater fishes: an heuristic checklist of the freshwater fishes of Europe" in volume 52 of the journal Biologia.
