Korte beschrijving Morfologie | Morfometrie

This species is distinguished from its congeners by the following characters: strongly depressed head; a tubercle between eyes; numerous, densely-set granules covering whole body except abdominal area; small tubercles especially on head; tubercles in dorsal row 26-29, ventral row 21-24, upper lateral row up to 20 (smaller on caudal peduncle), in lower one 10 and are tiny; chin barbel slightly compressed with thick base, longer than half eye diameter; D1 IV; origin of D2 behind anal origin; transverse rows of neuromasts on flank usually 20-22; a dark spot often in front of D2; sides with dark blotches and irregular dots (Ref. 59043).

Biologie     Verklarende woordenlijst (bv. epibenthic)

Occurs in fresh and brackish waters with salinity up to 13 ppt. Maximum depth 50 m, with mature adults at 1-11 m. Lives for about a year, spawns in May-August in northern Caspian, April-November in eastern Caspian. Some individuals may spawn for the first time at 6-7 months. Females probably lay eggs in 3 portions and die after spawning while males probably die 3-4 weeks alter (Ref. 59043).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00290 - 0.02870), b=2.98 (2.72 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.2   ±0.3 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (tm<1).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
