|Red List Category & Criteria:||Critically Endangered B1ab(v) ver 3.1|
|Reviewer(s):||Smith, K. & Kottelat, M.|
This species has a very restricted range, Visovac Lake in the lower Krka drainage (extent of occurrence estimated to be 20 km²). It is currently experiencing a population decline, but the reasons for this are unknown. Pollution from two towns (Knin and Drnis) could be a cause. A study is currently under way to determine the threats and conservation measures for the species.
For the European Union 27 assessment, this species is recorded as Not Applicable (NA); it is not found within the European Union.
