Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 0; Taggstrålar i analfenan 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.

Biologi     Ordlista (t.ex. epibenthic)

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.
