Baturevych O. Rearing carp with the use of minerals with sorption properties

The dissertation is devoted to the development of ways to increase the efficiency of growing groups of carp of different ages by using minerals with sorption properties of bentonite, analcym and saponite, according to their functional characteristics. Optimal norms of introduction of minerals to the carp diet in the amount of: saponite - 3.0%, analcym - 3.0%, bentonite - 2.0% in accordance with the analysis of productive, physiological, biochemical and economic indicators obtained in laboratory and field studies. The use of 5.0% saponite, 0.2% activated bentonite and 5.0% bentonite in the feeding of female carp in order to improve the quality of the obtained caviar and optimize the reproductive functions of the fish organism has been scientifically substantiated. The influence of different concentrations of minerals of volcanic origin on the chemical composition of water contaminated in the process of fish farming was studied and the introduction of analcym into reservoirs at the rate of 200 kg / ha was recommended to improve the hydrochemical regime.
