Description synthétique
Clés d'identification | Morphologie | Morphométrie
Diagnosed from its congeners in Baltic and Black Sea basins by the following characters: longitudinal epithelial crests on predorsal scales; scales on lateral line 39-42 + 2; scale rows around caudal peduncle 14-16, rarely 12; dorsal fin with 7½ branched rays; anal fin with 6½ branched rays; dorsal behind middle of body, predorsal length greater than postdorsal length; anus closer to pelvic origin than to anal origin; snout longer than or equal to postorbital distance (Ref. 59043).
Body shape (shape guide): elongated.
Inhabits bottom of moderately flowing lowland rivers and prefers sand bottom. A nocturnal species feeding on insect larvae and other larger benthic invertebrates (Ref. 59043).
Cycle de vie et comportement reproducteur
Maturité | Reproduction | Frai | Œufs | Fécondité | Larves
Both sexes move to surface or open water to spawn (Ref. 59043). Females spawn up to 4 times during a season at about two-week intervals (Ref. 59043).
