简单描述 型态特徵 | 形态测量图

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).
在后部的脑颅宽度 71.4-83.9% 的头盖顶部长度; 头盖顶部长度的前面脑颅宽度 30.9-40.7; 眼直径 1.5-2.6个倍眼间距; 眶上而眶下的知觉头部的管分离。 (参考文献 52363)

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).
营养阶层 (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.
回复力 (Ref. 120179):  高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
