Abstract:

The Vâlsan river (surface - 358 km2, length - 84.6 km) springs from the bottom of Făgăraş mountains from the glacial hollow, from an altitude of 2310 m, flows parallel with Argeş river, wonder through the same relief group up to the river mouth, in Merişani. In the year 1967, the Vâlsan river had suffered important modifications by constructing upstream of Vâlsan gorge a storage lake and also a hydroelectric–plant. The special interest of Vâlsan River is the presence of the fish species Romanichthys valsanicola (sculpin perch), an endemic species to the Danube basin. It is considered the most endangered species of European ichthyofauna because of its narrow range (only a sector of Vâlsan) and small number of individuals. The paper presents data referring to the structure of the ichthyofauna of the Valsan River, during the period 2014 - 2015, distribution of species along river and a comparative analysis of the structure ichtyofauna, now and in the past. Biological material was sampled at 16 sites. 1224 individuals were captured. A total number of 8 fish species were identified, including Romanichthys valsanicola.
