Abstract

Actuality of work is determined by the need of fisheries development based on innovative technologies of industrial cultivation of fish with the use of closed systems.The objects of study – the types of fish farmed in the recirculating aquaculture system and with balicasan a number of plants suitable for cultivation. Purpose – based closed systems for growing fish and plants, adapted partially or completely, with biologically filter replacement PhotoFiltre a comprehensive study. The collection and processing of materials, hydrochemistry, biology, ichthyology was carried out according to methods accepted in the industry as a whole. The level of survival of different types of plants and fish, the rate of growth, a comprehensive research on a number of parameters, such as the influence of hydrochemical order.Identified plant species and habitat fish little Sabespkergand at a loss.Different climatic, hydrochemical, ichthyological and the growth rate of fish and plants, cultivated in most of the cases phytologically, the estimation laws.Nitrifiersbiofilter the purification of water used in bacteria, fish, plants, absorbing, re-installation is composed of vessels using the system of fish culture by replacing dead-end metabolites PhotoFiltre feature. Scientific novelty for the first time on the basis of studying various species of fish аt a concentration of valuable herbal products of metabolism and along improved methods of fish cultivation.
