Coregonus gutturosus, the Lake Constance whitefish, is an extinct species of whitefish in the salmon family Salmonidae.[2] It was formerly found only in deep areas of Lake Constance in the Alps.[3]

Extinction[edit]

Coregonus gutturosus was a deep water whitefish that reached a length of 29 cm (11 in). Coregonus gutturosus was highly sensitive to environmental changes and it is thought that the eutrophication of Lake Constance, which peaked in 1979, irreversibly affected the development of the eggs of the species.

Surveys undertaken in the last ten years failed to find any evidence of the survival of the Lake Constance whitefish, as well as of the Lake Constance Deepwater char (Salvelinus profundus), another similarly endemic fish species driven recently to extinction in that lake.[4]
