Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
This species is distinguished from its congeners by the following characters: head length 29-31% SL; eye diameter 16-21% HL; anal rays 14-16; total scales in midlateral series 43-49 (Ref. 59043).
Inhabits a variety of slow-flowing or still waters; usually associated with dense vegetation or coarse rocks. Spawns for the first time at 1-2 years, and usually only for 1 to 2 seasons, April-August with females spawning more than once during a season. Males guard the eggs which are deposited in cavities; larvae and juvenile are benthic. Feeds on benthic invertebrates. It is invasive in Volga where reportedly, the spreading was due to canalization of main river and reservoirs or slow-flowing waters created by hydroelectric plants (Ref. 59043).
