This research is aimed to study the effect of lipid composition in diets on ovicell generating of the Russian sturgeon females. Addition of fish oil in number of 9% (with 12-13% total fat content in mixed fodder) proved to be an opti-mal rate of mixed fodder supplement with fish oil for both commodity sturgeon farming and pre-spawning maintenance of breeders with the view of improving the quality of the live fertilized roes and caviar alike. According to the data of biochemical analyses of the sturgeons body composition, hematological indices, growth rates and general condition of the cultivated fish the effect was rather positive. At a minimum expenditure of fodder the body weight gain of the fish body in these series of experiments amounted 3.2% with maximum possible level of survivability (100%). Besides being highly nourishing fish oil also attracting.
