ABSTRACT. The article presents the research results of nanoparticles influence of Cu-Zn alloy with size of 55±15 nm and Bacillus subtilis culture (Vet 1.1 probiotic product) at the inclusion in diet of juvenile sterlet (Acipenser ruthenus) on exchange of toxic elements. According to the analogues principle, four groups were formed: control and three test groups. The probiotic product (25 mg/kg feed) was added to the diet of the 1st test group, nanoparticles of Cu-Zn alloy (2.84 mg/kg feed) were added to fish of the 2nd group, and the probiotic product (25 mg/kg feed) and Cu-Zn alloy nanoparticles (2.84 mg/kg feed) were added to the diet of the 3rd group. The inclusion of nanoparticles and Bacillus subtilis culture in fish diet both together and separately is accompanied by a decrease in the concentration of the toxic elements group in fish body: aluminum, silicon, arsenic, mercury and lead. Synergism of probiotic action and copper and zinc nanoparticles at simultaneous inclusion in diet is revealed. It leads to the reduction of the toxic elements concentration in fish body and to the stabilization of metabolic processes, the cells differentiation and the antioxidant status maintenance of fish body.
