Siberian sturgeon weighing 50 ±5 g, cultured in cages stocked at 45 specimens/m3 density and placed in cooling water, were fed Dan-ex 2545 trout feed for 112 days. Experimental treatments differed in the amount of ascorbic acid + glucose mixture (1 : 9) added to the feed. The mixture was applied, in individual treatments, in doses of 0; 1; 5; and 10 g/kg feed, corresponding to ascorbic acid doses of 0; 0.1; 0.5; and 1 g/kg feed. The highest mixture doses resulted in a significant increase in the fish body fat level; however, no significant effect on fish growth was observed.
