Краткое описание
определительные ключи | морфология | морфометрия
Distinguished from its congeners in Danube drainage by having the following unique characters: peritoneum black; anal fin usually with 11-12½ branched rays; and breeding males with two horizontal rows of large tubercles on side of head above eye, usually more or less fused into a continuous ridge (tubercles white in ethanol); and tubercles on body massive, occupying most of scale area. Can be further separated from other species of the genus in Danube drainage by the combination of the following characters: 44-46 scales along lateral line; mouth inferior; snout blunt; body laterally compressed, maximum body width about 50% of body depth; body greenish to bluish brown; iris silvery (Ref. 59043).
Inhabits medium sized to large rivers. Spawns in fast-flowing water of riffles over gravel or submerged plants. Attains a maximum size of about 40 cm SL (Ref. 59043).

Estimates based on models
Phylogenetic diversity index (Ref.

50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00358 - 0.01465), b=3.14 (2.98 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.4 ±0.5 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): низкий, минимальное время удвоения популяции 4.5-14 лет (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
