Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2014
Date Assessed: 2013-03-11
Assessor(s): Freyhof, J.
Reviewer(s): Ekmekçi, F. & Smith, K.
The species is endemic to Lake Hazer (82 km2) in upper Tigris drainage in Turkey. The water levels of Lake Hazer are declining, however the lake is very deep (1,600 m) and the species is pelagic. Therefore it is not thought that the declining water levels will impact the species, and there are no other plausible threats to the species. It is thought unlikely that non-native species that could impact A. asquamatus will be introduced. Therefore the species is assessed as Least Concern.

Conservation Actions [top]

Conservation Actions: Actually there are efforts to stop the shrinking of the lake.
