Short description Bestämningsnycklar | Morfologi | Morfometri

Posterior neurocranium width 71.4-83.9% of cranium roof length; anterior neurocranium width 30.9-40.7 of cranium roof length; eye diameter 1.5-2.6 times in interorbital distance; supraorbital and infraorbital sensory cephalic canals disconnected (Ref. 52363). Diagnosed from its congeners in Black and Caspian Sea basin by the possession of the following characters: eye diameter 1.5-2.6 times in interorbital distance; predorsal scales with longitudinal epithelial crests; scale rows around caudal peduncle 12-16; dorsal fin with 7½ branched rays; anal fin with 6½ branched rays; anus closer to pelvic origin than to anal origin; greatest head width 59-72% of dorsal head length (Ref. 59043).

Biologi     Ordlista (t.ex. epibenthic)

Inhabits streams and rivers stretches with fast current and gravel bottom (Ref. 59043). Feeds on Trichoptera larvae (Ref. 59043). Spawns at the end of May (Ref. 1441).

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=0.00603 (0.00290 - 0.01252), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.4   ±0.4 se; based on size and trophs of closest relatives
Generation time: 2.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resiliens (Ref. 120179):  Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
