Alosidae (Shads and Sardines)
Etymology: Alosa: Latin, alausa = a fish cited by Ausonius and Latin, halec = pickle, dealing with the Greek word hals = salt; it is also the old Saxon name for shad = "alli" ; 1591 (Ref. 45335).
Eponymy: Vladimir Konstantinovich Bražnikov (or Braschnikow) (1870–1921) was a Russian zoologist, ichthyologist and entomologist with an interest in Diptera who lived in Tokyo for many years. [...] (Ref. 128868), visit book page.

Ökologie
; brackwasser pelagisch; ozeanodrom. Temperate; 48°N - 35°N, 45°E - 56°E (Ref. 188)
Former USSR and Asia: Caspian Sea.
Länge bei der ersten Reifung / Größe / Gewicht / Alter
Geschlechtsreife: Lm ?, range 20 - ? cm
Max length : 50.0 cm SL Männchen/unbestimmt; (Ref. 188); common length : 30.0 cm SL Männchen/unbestimmt; (Ref. 188)
Rückenflossenstacheln (insgesamt) : 0; Afterflossenstacheln: 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.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
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.
