Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
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).

Estimates based on models
Índice de diversidade filogenética (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 (2.97 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nível Trófico (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.
Resiliência (Ref.
120179): médio(a), tempo mínimo de duplicação da população 1,4 - 4,4 anos (K=0.20; tmax=11).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (50 of 100).
Nutrients (Ref.
