Ehiravidae (River sprats)
Etymology: Clupeonella: Latin, clupea = sardine, derived from Clupeus = shield; diminutive (Ref. 45335); abrau: abrau taken from Lake Abrau found near the city of Novorossiisk in the northern Caucasus (Ref. 72388).

Ökologie
; süßwasser pelagisch; standorttreu (Ref. 72388). Temperate; 5°C - 28°C (Ref. 72388); 43°N - 37°N
Europe: Lake Abrau (freshwater, landlocked, at 70 m above sea level, near to Novorossiisk) in Russia; not Lake Apolyont (Turkey), which is linked to Sea of Marmora.
Length at first maturity / Size / Gewicht / Alter
Maturity: Lm 4.0, range 4 - 4.5 cm
Max length : 9.5 cm SL Männchen/unbestimmt; (Ref. 188); max. veröff. Alter: 2.00 Jahre (Ref. 72388)
Rückenflossenstacheln (insgesamt) : 3; Rückenflossenweichstrahlen (insgesamt) : 13 - 21; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 12 - 23. Body moderately slender, its depth about 19 to 23% of standard length; head short and narrow, interorbital width not more than 17.5% of standard length; belly sharply keeled, with 23 to 26 scutes. Pectoral fin tips pointed. Pterotic bulla absent. No notch at the center of the upper jaw. Last two anal fin rays enlarged.
Forms schools. Feeds on crustaceans (juveniles feed on copepods, rotifer eggs and plants). Breeds from May to October. The eggs are pelagic, developing rapidly before sinking to the bottom. Matures at 1 year, at 3.5 to 4.5 cm SL.
