Alburnus sava Bogutskaya, Zupančič, Jelić, Diripasko & Naseka 2017

Alburnus sava can be diagnosed from all its congeners in the Danube drainage by having the following characters: 23?27, usually 24?26, gill rakers; the ventral keel usually completely scaled (scaleless maximum 15% of the keel length); pectoral fin with 15?16 (mode = 15) branched rays; length of gill raker 65?70% of the length of the opposite outer gill filament; and a relatively long lower jaw (37?40% HL, 112?130% interorbital width) (Ref. 116758).

Potamodromous. Migrating within streams, migratory in rivers, e.g. Saliminus, Moxostoma, Labeo. Migrations should be cyclical and predictable and cover more than 100 km.

Dorsal soft rays (total): 11; Analsoft rays: 18 - 19; Vertebrae: 44 - 45

It inhabits streams and rivers with moderate to rapid current and a gravel and cobble bottom. During the spawning season in spring, it migrates upstream to smaller tributaries to shallow riffles where they spawn (Ref. 116758).
