Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; depth range - m (Ref. ), usually - m (Ref. ). Temperate; 0°C -
Europe: Tisza system, Danube drainage in Ukraine. Available molecular data suggest that the upper Tisza and Mureş populations may represent distinct lineages.

Morphology | Morphometrics
Diagnosed from other congeners in Black and Caspian Sea basin by having the following characters: breast naked between pectorals or only a few scales along midline; barbel extending between middle of eye and posterior eye margin; snout length 0.9-1.0 times in postorbital distance; head length 25-28% SL; head depth at nape 15-17% SL, at eye 44-50% HL; body depth 18-25% SL; head width 14-16% SL, 56-63% HL; eye diameter 4-6% SL, 2.7-3.4 times in head depth, 1.4-1.7 times in interorbital distance (at 7-11 cm SL); caudal peduncle depth 31-39% HL (Ref. 59043).
Occurs in a wide variety of habitats in small rivers and streams. Size reaches up to about 12 cm SL (Ref. 59043).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00298 - 0.01684), b=3.14 (2.97 - 3.31), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
