Only known from a single lake, Lake Breiter Luzin (3.5 km²), where the population heavily declined, in the 1970s, due to euthrophication, but is now recovering along with improved water quality. There are no current threats to the species but the introduction of alien species is a potential threat even though part of the lake basin is within a protected area.

|Population:||Since the 1970's, when the lake was eutrophic, the species has increased in abundance along with the water quality.|
|Current Population Trend:||Increasing|
|Habitat and Ecology:||Habitat: |
Lacustrine, reported to inhabit deep water layers (20-58 m) and move to shallow waters to spawn. Lake Breiter Luzin is a 3.5 km² mesotrophic lake (formerly oligotrophic), maximum depth 85 m.
Lives up to six years. Matures at two years. Spawns in April-July, usually May-June. Feeds mainly on chironomids and Mysis relicta.
|Generation Length (years):||3|
|Major Threat(s):||The species survived heavy eutrophication in the 1970s, caused by sewage and agricultural pollution. Stocking of alien species is a potential threat to the species.|
|Conservation Actions:||Part of the catchment is covered by a nature reserve.|
