One of the most significant factors in regulating the parameters of redox reactions occurring in any liquid medium is the electron activity or redox potential (RP) of this medium. Water that has a negative RP is easily absorbed by the body and replenishes the cells with lost negative charges and energy. As a result of the conducted studies, it was found that the hydrochemical parameters in the experimental and control variants were within the standard values for growing tilapia juveniles. It was found that the redox potential of the blood of juvenile tilapia has a negative value of - 96 mV. It is recorded that at a sufficiently low water temperature for thermophilic tilapia (21 °C) and at a negative RP (-212 mV), a high growth rate of fish is observed. It was found that the use of water with a redox potential of -100 mV is the most effective, since the linear weight gain of juveniles increases by 41 % in comparison with the control. Tilapia juveniles grown in structured water have the highest levels of hemoglobin (62-64 g/l) and total serum protein (13.3-14.3 g/l).
