Description

Sterlet reaches up the length of up to 125 cm and weight of 16 kg. This is the smallest sturgeon species in the Danube. It does not migrate to the sea and that is the difference between its relatives. It spends all life in the river, usually in the area of the parent waters or, during the winter stagnation, in the deep depressions of the river bottom.


It feeds on invertebrates from the river bottom, primarily insect larvae. The spawning period is from April to June in the fast water flows over a gravel bottom. Sexual maturity is attained at 4-5 years. It lives around 25 years. It is extremely commercial fish caught by fishnets in the early spring.
