The review of literature sources that reflect the peculiarities of closed water systems (RAS) in aquaculture using bio filters with different types of filler for water cleaning. Deals with the importance of mechanical and biological filtration for RAS. Biochemical and microbiological processes inside the bio filters with movable and immovable fillers were deliberated. The attention on the need to maintain the viability of denitrification bio filters microflora. The basic factors that influence the efficiency of industrial enterprises with growing rainbow trout. The necessity of daily monitoring of water quality in RAS to prevent epizootic and nitrite poisoning grown fish. It is noted that veterinary measures in accordance with established diagnosis should be carried out in such a way that by helping one body (rainbow trout), does not affect the other (bio filters of the filtration filler). The conclusion about the need for more detailed study of the composition, physiological characteristics and biofilters role as a concomitant body during the growing aquaculture objects.
