The article presents the results of studies of the dynamics of hydrochemical indicators of water in the integrated cultivationof fish and plants. A recirculating aquaculture system, with a volume of 1500 liters, contained the following fish: Acipensergueldenstaedtii, Carassius gibelio, Tinca tinca, Cyprinus carpio, on the 36th day of the experiment, a growbox was connectedto the system where Lollo Rossa Lettuce was grown. During the experiment, the water in the fish tank was not replaced orrefilled. The dynamics of changes in the hydrochemical parameters of water when using the aquaponics module after connectingthe growbox can be attributed to the fact that plants with a developed root system consume nitrogenous compounds. There aremore active processes of the movement of carbohydrate substances in the system, the pH is stabilized. The accumulation ofbiogenic substances observed in the experiment indicated an insufficient number of their utilizers — plants.
