An Experimental Study of the Effect of Natural Zeolite of Chankanay Deposits on Fish-Breeding and Biological and Hematological Parameters of the Body of Fish

摘要

This paper presents the fish-breeding and biological and hematological substantiation for the useof natural zeolites of Chankanay deposits of the Almaty region as a component of mixed production fodder fortrout. As a result of studies we have determined the possibility of application of natural zeolite in the amountof 1 and 3 % as part of mixed production feed for trout. It has been also found out that the introduction ofzeolite into mixed fodder had a positive effect on the growth of two-year-old trout and its physiological state.Absolute growth of trout in case of adding zeolite in the amount of 1 and 3% compared with to the control wasequal to 116 and 105 % respectively. Average daily gain in the first version was higher than those of the controland the second experimental group by 0.32 and 0.15 g. The survival rate in all cases was 100%. The hemoglobincontent in the blood of rainbow trout in experimental samples increased slightly and equaled 9.8 ± 0.36(with addition of 1% of zeolite) and 9.6 ± 0.39 g/l (at 3% addition of zeolite), respectively; in the control thisfigure was-8.7 ± 0.57 g/l. In the numbers of leukocytes as well as the numbers of immature erythrocytes,there have been no differences between the samples. Monocytes and lymphocytes also remained within normallimits.
