ABSTRACT. Increasing the productivity of aquaculture objects is integrally related to the search for new feed additives which are capable of increasing growth intensity and improving the physiological state of fish. The article presents the study results of the effect of iron nanoparticles with a size of 100 ± 2 nm, and its combined effect with Bifidobacterium bifidum culture and the Rovabio XL enzyme preparation on the fish elemental status with the diet inclusion. The test additives supplementation in the carp diet positively affects the mineral metabolism in fish body, which is noted by an increase in the content of essential trace elements Mg, Co, Zn, Cu, Se, Fe, Cr and a decrease in the pool of toxic elements in fish body. The most promising from the point of view of increasing live mass and key essential trace elements in fish body is sharing Fe NP and Bifidobacterium bifidum probiotic.
