A very rare and declining species found in only one location, Lake Ammersee (41 km², the deep water where the species occurs is probably an area of less than 10 km²).
The species has only been recorded three times by local fisherman since 2000. It used to be a commercial species supporting a fishing industry in the 1940s. However the decline is suspected to have occurred in the 1970s when the eutrophication was at its peak. This species may be on the verge of extinction as the lake is still mesotrophic.
