The species is known from Drin river basin including Lake Skadar basin (Serbia and Montenegro) and Lake Ohrid (Albania and the former Yugoslav Republic of Macedonia (FYROM)) and all Albanian rivers draining to the Adriatic south to Aoos river basin in western Greece.  Even though the habitats are impacted by pollution and dams, the species is quite abundant and obviously capable to survive in reservoirs and polluted habitats. It isn't expected to have undergone a population decline of more than 30% in the past 10 years. It is therefore assessed as Least Concern.

European Union 27 = LC. Within the European Union the species is only recorded in the Aoos river basin in western Greece, flowing into Albania where it is called the River Vijose. Here the species is abundant. It is therefore assessed as LC for the EU 27 also as only the drying up of the river due to water abstraction and climate change seems to be a realistic threat and this is not expected to happen in the near future.
