摘要：
FIELD: agriculture.SUBSTANCE: group of inventions relates to industrial fish breeding and can be used to grow commercial fish species in closed water supply systems. Method to grow commercial fish species in closed water supply system is characterized by arrangement of fish in water-filled tanks for its growing, periodic feeding with maintenance of water and water supply parameters. Amount of water supply into nitrifier is set within range of values from 7 to 14 of nitrifier container volume per hour at surface washing rate of latter from 0.17 to 0.48 from nitrifier height meters per minute. Amount of water supply into denitrifier is set within range of values from 9 to 1.2 of denitrifier container volume per hour at surface washing rate of latter within range of values from 0.029 to 0.031 from denitrifier height meters per minute. Water temperature is maintained within range of values from 11 to 28 degrees Celsius, and water pH is maintained within range of values from 7.0 to 7.2. Oxygen concentration in water at nitrifier inlet is maintained at level of not lower than 4.4 mg/l, and concentration of oxygen at denitrifier inlet is maintained within range of values from 0.9 to 1.2 mg/l. Carbon dioxide concentration in water at pump inlet is maintained within range of values from 15 to 25 ml/l. While maintaining parameters at specified level performing continuous mechanical filtration of water with supply of fresh water from outside into air channel within range of values from 0.5 to 0.9 of nitrifier volume per day. In second embodiment, maintenance of water parameters and water supply parameters at specified level is performed using computerized control system based on PC computer program ACS UZV based on information, which is supplied from sensors of water level, water transparency, oxygen content in water and carbon dioxide content in water, as well as water pH and water temperature.EFFECT: group of inventions technical result consists in increase of industrially c
