Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 27 - 48; Anale zachte stralen: 16 - 35. Under the name A. g. colchicus. Lower lip not continuous, interrupted at center. Five rows of scutes: dorsal 7-19, lateral 24-44 on each side, ventral 6-13 on each side, with lines of smaller stellate bony plates between the dorsal and ventral rows. Color of back olivaceous grey, flanks lighter, and belly white.

Anadromous and freshwater populations exist. At the sea, it occurs in shallow coastal and estuarine zones. In freshwaters, it inhabits deep parts of large rivers with moderate to swift current (Ref. 59043). Found mainly near the shore over sand and mud. Usually solitary, but swarms when hibernating or during spawning migrations. Occasionally forms schools (Ref. 3241). Feeds on benthic molluscs, crustaceans and small fishes. Spawns on stone or gravel bottom in large and deep rivers with strong current, 1-1.5 m/s (Ref. 59043). Mainly propagated through artificial reproduction.

Estimates based on models

Preferred temperature (Ref. 123201): 10.7 - 15.9, mean 13.8 °C (based on 32 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00437 (0.00268 - 0.00711), b=3.12 (2.99 - 3.25), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
