Impact of Saccharomyces cerevisiae on Growth Performance of Carp Fish Exposed to CuSo4

Abstract

Abstract Contaminants are one of the biggest determinants of fish farming, and Cuso4 is considered one of the most important factors of pollution on microorganisms. Probiotics are among the most important feed additives and have a major role in improving the condition of fish. Yeasts, especially Saccharomyces cerevisiae, are considered one of the best additives that have a role in reducing the effect of copper on fish. Therefore, our study was done in adding yeast to the diet to reduce the effect of Cuso4, and This experiment was conducted in the fish laboratory of the Department of Animal Resources / College of Agriculture and Forestry / University of Mosul, where fish were brought from Erbil Governorate / Tarjan hatchery in ideal transport conditions and the fish were acclimatized in Ponds outside the laboratory for a week, after which the fish were sterilized with salt, and then the fish were transferred to the laboratory and after randomly distributing them with a weight of 35+-2 with 7 fish for each pond by 12 ponds every 3 treated ponds. The first treatment included the second control, the third yeast Cuso4, the fourth yeast and cuso4 and continued The experiment lasted for 56 days, and after the end of the experiment, it was noted that the yeast had improved the weight and growth parameters in general, and the yeast had reduced the effect of Cuso4 by the fourth treatment.
