Length at first maturity / Tamanho / Peso / Idade
Maturity: Lm ?, range 20 - ? cm
Max length : 50.0 cm SL macho/indeterminado; (Ref. 188); common length : 30.0 cm SL macho/indeterminado; (Ref. 188)
Espinhos dorsais (total): 0; Espinhos anais 0. Body fairly elongate, more `herring-like' than `shad-like'. gill rakers thick and coarse, shorter, equal to or a little longer than gill filaments, either straight or curved, pointed or blunt, occasionally even bifurcated at tips. Teeth well developed in both jaws. Other Caspian shads have deeper, more shad-like bodies.
Occurs in brackish water and non-anadromous, but strongly migratory. Feeds on small clupeids, gobies, atherines, also crustaceans and occasionally insects and mollusks. Spawning patterns among the subspecies vary but occur mostly in spring and summer after an inshore migration and movement northward.

Nível Trófico (Ref.
69278): 3.9 ±0.4 se; based on diet studies.
Generation time: 3.1 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resiliência (Ref.
