Kunci identifiaksi (pengenalan) | Morfologi | Morfometrik
Mouth oblique. Low wavy lateral line. Belly with a sharp edge (Ref. 35388).
Adults shoal in lower reaches of large rivers and in the eastern Baltic, the Caspian Sea and the Aral Sea. They spawn in spring in midstream (Ref. 9696) and return to estuaries to forage immediately after spawning (Ref. 59043). Juveniles may migrate to estuaries during first summer (Ref. 59043). Feed on zooplankton, terrestrial invertebrates and small fish (Ref. 59043).
Open water egg scatterers.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00358 - 0.01465), b=3.14 (2.98 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.53 se; based on food items.
Generation time: 10.0 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Daya lenting (Ref.
120179): sedang, Waktu penggandaan populasi minimum 1.4 - 4.4 tahun (K=0.20; tmax=11).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (50 of 100).
