Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(ii,iii,v)+2ab(ii,iii,v) ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01
Assessor(s): Freyhof, J. & Kottelat, M.
Reviewer(s): Bogutskaya, N., & Smith, K. (IUCN Freshwater Biodiversity Unit)
Justification:
The species is known from five streams on the Crimea with an extent of occurrence of less than 1,000 km² (area of occupancy of spawning sites estimated to be less than 500 km²). It is threatened by pollution (Salgir stream), water abstraction (Alma, Chornaya, Kacha) and river regulation (Chornaya). It's presence in Salgir needs to be confirmed, it is rare in Kacha and Chornaya streams, almost extirpated in Alma but still abundant in the Bel Bek stream.
