Short description Bestämningsnycklar | Morfologi | Morfometri

Diagnosed from congeners in Black and Caspian Sea basins by the following characters: strongly arched mouth; dorsal fin usually with 8½ branched rays; anal fin with 9-10½ branched rays; scales on lateral line 56-73; eye small, diameter 48-52% of interorbital distance; and body cylindrical, width at dorsal origin 51-69% of depth (Ref. 59043).
Body shape (shape guide): elongated.

Biologi     Ordlista (t.ex. epibenthic)

Inhabits piedmont and mountain rivers with strong current and rock to gravel bottom. Feeds predominantly on detritus and also on periphytic algae and benthic invertebrates, especially during first year of live. Spawns over hard bottom (Ref. 59043).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver

Females deposit eggs probably in several portions. Eggs adhere to gravel (Ref. 59043).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00374 - 0.01767), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  2.4   ±0.1 se; based on size and trophs of closest relatives
Resiliens (Ref. 120179):  Mycket låg, lägsta populationsfördubblingstid mer än 14 år (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (42 of 100). 🛈
