This species was present in two large lakes from where it has vanished due to pollution and desiccation of the lakes. It is now only known from one lake tributary (estimated at 10 km long). The population in this tributary is suspected to be declining due to water abstraction and pollution. It is therefore assessed as Critically Endangered.
The species is known from Eber and Akşehir lakes, Turkey, including the inflowing streams. However the species is now only found in one tributary (Ortaköy - estimated at 10 km long) of Lake Akşehir only. Bleaks of Lake Ilgin basin may also belong to this species but due to taxonomic uncertainties, this population is ignored for the assessment.

The only remaining population is at one inflowing stream (Ortaköy) to Lake Akşehir. The species has declined and disappeared from most of its range.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:|
This was a lacustrine species with small resident populations in tributaries. The lacustrine parts of the population are lost and it now only inhabit streams with moderately or slowly flowing water.
|Movement patterns:||Not a Migrant|
|Major Threat(s):||Massive water abstraction has reduced the lake levels drastically and heavy pollution has made them to an uninhabitable place for fishes. The remaining population in Örtaköy stream face high pollution levels as well as often very low water levels due to water abstraction. Growing human populations will increase water abstraction in future and climate change induced less rainfall will shrink the available water resources.|
|Conservation Actions:||There is no conservation in place for this species, but both lakes are protected areas. The only known stream inhabited by this species is not protected. Habitat restoration and biodiversity oriented water resource management would help to save the unique freshwater biodiversity of theses lake basins. Fieldwork is further recommended to better understand the distribution of the species and threats in the lake tributaries.|
