Abstract
The purpose. To study growth of rainbow trout and productivity of mixed fodder at merchantable growing of this fish in basin fishery with use of river water. Methods. Fish was grown using the technique of growing rainbow trout. Results. Features of accumulation of mass by fish depending on seasonal fluctuation of temperature and saturation of water with oxygen are fixed. Parameters of aquatic environment for the most efficient accumulation of mass by two-year-old fishes of rainbow trout as well as use by fish of mixed fodder are specified. At the temperature of water 18°C and density of the oxygen dissolved in it not below 8 mg O2/l growth rate of a fish was maximum, and the feeding ratio did not exceed 0,84. Conclusions. Technological environment of basin farm was favorable for deriving merchantable output of rainbow trout for 8 months.

Key words: rainbow trout, temperature of water, density of oxygen, accumulation of mass, feeding ratio.
