Abstract

The paper outlines the problems of fish rearing in the water with negative redox potential. Water is known to consist of supermolecules, the so-called clusters and cells, connected by a special molecular structure. This structure changes when exposed to water in different ways: chemical, electromagnetic, mechanical. Under these influences the water molecules rearrange forming the structured living water. The effectiveness of activated water is explained by the fact that in the process of electrolysis the dead water acquires a positive electric potential, and living water – a negative electrical potential. It becomes a weak electrolyte which quickly interacts with body fluids (gastric juice, blood, lymph, intercellular fluid, etc.). As a result of the studies carried out on juvenile tilapia, it has been found that the hydrochemical parameters in the experimental (growing in structured water) and control variants were within the standard values. Concentration of O2 made 7 mg/l, pH of the medium was 7.2, and nitrite concentration was 0.3 mg/l. It has been inferred that the redox potential (redox) of the blood of young tilapia has a negative value 
 (–96 mV). It has been recorded that at a water temperature of 21°C that is sufficiently low for thermophilic tilapia and at a negative redox (–212 mV) there has been observed a high growth rate of fish. It was found that the use of redox water (–100 mV) is most effective, because the linear-weight gain of juveniles increases by 41% in comparison with the control. Negatively charged (cathode) water increases the efficiency of rearing tilapia fry and does not affect the physiological state of fish. Tilapia fry reared in the structured water have the highest hemoglobin content (62-64 g/l) and total protein (13.3-14.3 g/l).
