ABSTRACT. The aim of this study was to determine the impact triploidization has on the following biochemical indicators of Siberian sturgeon (Acipenser baerii Br.): glucose, triglycerides, total protein, albumin, total globulin, creatinine, ammonia, calcium, magnesium and alkaline phosphatase, creatine kinase, and lactate dehydrogenase. The experiment was performed on juvenile specimens of the species with a mean total body length of 22.3 ± 2.9 cm and a mean body weight of 75.3 ± 40.7 g. Despite changes observed in the concentration and activity of some indicators, no statistically significant differences were noted in comparison to the control group. The greatest discrepancies were observed in creatine kinase (with activity that was 95% lower in the triploid group), which could indicate disruption in skeletal muscle function in the fish with increased ploidy.
