Extinction
Together with the equally extinct Gravenche (Coregonus hiemalis) it was one of the most caught freshwater fishes in the Lake Geneva. In 1890 the fishing quota of these two fishes made 68% of all caught fishes in Lake Geneva. Due to overexploitation in combination with the heavily hybridisation with introduced coregonus species it became extremely scarce in the 1920s. It was still present in 1950 but was not found again in 1958.
