Abstract
Methodology. The study was conducted at Lviv Experimental Station of the Institute of Fisheries NAAS according to generally accepted aquacultural rules of experiments and repeats. The object of the study were age-2 carp. The weight part of protein was determined acc. to Kjeldahl method, fat content acc. to S. Rushkovsky method. Hemoglobin content in fish blood was determined using hemoglobin-cyanide method (with atsetonninhidryn). The number of red blood cells was counted in a Goryaev chamber. The obtained data were processed statistically using standard statistical package of Microsoft EXCEL. Findings. The use of amaranth in the feeding of age-2 carp has positive effect on their growth and survival, nutritional value of fish flesh, and results in an increase of hemoglobin in blood. It was found that the addition of 10% ground amaranth seeds and 5% amaranth oil during the entire growing season resulted in an increase of mean weight of carp by 4.2 and 5.2% and in an increase of fish productivity by 5.9% and 7.1%, respectively. Feeding of carp with a feed supplemented by amaranth contributed to an increase in protein content in fish muscles by 2.07% (P <0.01) and 1.30% (P <0.05), respectively. The number of red blood cells in the blood of carp fed with ground amaranth seeds increased by 10.2%, while in those fed by amaranth oil - by 3.7% compared to the control group of fish. Hemoglobin content after feeding of fish with amaranth oil increased by 6.79%. Amaranth is added to the fish feed mixture to replace cereal component after heat treatment. Originality. Despite high nutritional, food and medicinal properties, amaranth is not used in fish farming as a feed additive. According to the obtained results, we developed the norms and methods of supplementing the basic diet of age-2 carp with this additive. Practical value. Implementation of the obtained results will provide an opportunity to increase fish productivity in ponds through feeding of fish with artificial feeds of improved composition. This will allow reducing the cost of artificial feeds, obtaining higher growth rate, and improving physiological parameters of cultured carp.
