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 system stalled and uneven-age groups of tilapia fish installation.
Purpose – a comprehensive study of methods of determination of economic efficiency of cultivation of various biotechnical methods and technologies for fish growing tilapia. Is collecting and processing materials by methods generally accepted in ichthyology and hydrochemistry areas, the analysis is composed on a personal computer. Tilapia-year survival level in a variety of different fish groups, the rate of growth, a comprehensive research on a number of parameters, such as the influence of hydrochemical order.Supplier Dernisation ages and with a big trapelate favorable conditions and cultivation. The main hydrochemical and
ichthyological growth rate of fish grown in various conditions, assess the patterns. Cleaner water horizontal biofilter large, sandy lane features system power the pumping unit is composed by a reconstruction of the inclusion in bilateral filtre fish farming.
Scientific novelty for the first time in the conditions of bioengineering methods maintenance and cultivation of fish In fish farms In the tilapia is cooked and absorbed. The results of the study are applied in fish farms using systematically closed fish plants. The study identified the main parameters of obtaining planting material and cultivation of products.
