Significant differences between morphometric features were observed such as acrosome length, acrosome width, head length, midpiece width and flagellar length. while midpiece length did not reveal such differences. The sterlet has a shorter spermatozoon than the Siberian sturgeon. Ultrastructural parameters vary significantly in terms of length of the nucleus, diameter of the endonuclear canals (EC), size of posterolateral projections (PP) and diameter of flagellum. Significant differences were observed in Na(+), K(+) and Cl(-) concentrations in the seminal plasma as well as in sperm velocity.The observed biochemical and physiological differences should be also considered for the development of methods for controlled reproduction and for sperm cryopreservation techniques.
