In this paper, the dependence of the temperature conditions of incubation of microbiological water cultures taken directly from the pool of a closed water supply system on the activity and species diversity of the resulting microflora is analyzed. The object of the study was clarias catfish (Clarias gariepinus), which was grown at a temperature of 22-24 °, Ph 6.5-7.5, which corresponds to the optimal requirements for breeding this type of fish. The study was conducted on the basis of the Russian-Norwegian Center for Research in the field of Innovation and Aquaculture of the MSUTM named after K.G. Razumovsky. As a result of the study, a reliable regularity of the activity of aquatic microflora in CFU / ml, as well as generic and species affiliation, was revealed.
