Abstract

Symbiotic species of plants and fish are identified, which will give the greatest yield of production when co-cultivated with minimal external impact. An estimation was made of the regularity of the growth rate of plants in various climatic, hydrochemical and phytological conditions. The installation of closed water supply was re-equipped, by constructive replacement of the biological filter,
using denitrifying bacteria, on a phytofilter that absorbs metabolic products by plant roots.
