Abstract: Currently, it is important to use biologically active substances in fish diets to increase productivity and reduce economic costs. Also, the additional use of drugs has a positive effect on the physiological state of the body. This study presents the results of studying the effect of a complex of biologically active substances on the concentration of chemical elements in carp muscle tissue. We used two complexes: I – vanillin + ultrafine particles SiO2 and II – vanillin + ultrafine particles SiO2 + enzyme preparations Amylosubtilin and Glucavamorin. The substances were applied to the KRK-110 feed by spraying: vanillin at a dosage of 250 mg/kg of feed, ultrafine particles SiO2 – 200 mg/kg of feed, Amylosubtilin – 0.5 g/kg of feed, Glucavamorin – 0.5 g/kg of feed. The object of the study was carp yearlings. According to the results of the study, it was found that complexes of biologically active substances have a positive effect on the live weight of carp, leading to a growth-stimulating effect (P?0.05) from the sixth week of the study. During the study, it was found that complexes of biologically active substances do not affect the pool of macronutrients in comparison with the control. We have noted a general tendency towards a decrease in the pool of essential and conditionally essential trace elements. For group I, a decrease in a number of trace elements was found from 22.6% (P?0.05) to 40.7% (P?0.01) compared with the control, for group II – from 21.8% (P?0.05) to 46.3% (P?0.001), with an increase in vanadium by 69.1% (P?0.05). When studying toxic elements in fish tissues, a decrease in the pool of elements in groups I and II was found for such indicators as arsenic, mercury and tin – by 30.1% (P?0.05) and 23.3% (P?0.05), by 44.2% (P?0.01) in group I and by 45.3% (P?0.01), by 35.7% (P?0.05) and 32.1% (P?0.05) in group II. Also, in group I, the level of aluminum decreased by 60.4% (P?0.001) and beryllium by 48.9% (P?0.05) relative to the control.
