Aquaponics installation using soil in waste water from fish farms

The paper presents the results of the study on the cultivation of lettuce (lactuca sativa kucheryavec odesskiy) in an aquaponics installation using soil in the conditions of closed water supply systems installations developed on the basis of the Russian-Scandinavian aquaculture center of the BiRH Institute of K. G. Razumovsky Moscow State University of Technologies and Management, Moscow. As a result of which, growth and productivity indicators of lettuce in an aquaponics installation were obtained. Hydrochemical studies made it possible to determine the efficiency of consumption of nitrates and phosphates at the maximum plant phytomass and to calculate the optimal power of the hydroponic installation for a given volume of fish tanks.
