Comparative characteristics of the biochemical composition of the body of fingerlings and yearlings of the amur carp from the belarusian collection herd

The article presents data on the biochemical composition (dry matter content), moisture, fat, protein and mineral substances of fingerlings and yearlings of the Amur carp and the average values for the collection carp of Belarusian and foreign breeding. Imported genetic material (milk) was used in the formation of the first and third generations of the ninth generation of the Amur carp collection. In order to minimize the influence of the environment on the results obtained, a comparative assessment of the biochemical parameters of the experimental groups was carried out separately for each of the growing and wintering options. The average dry matter content in the body of fingerlings of the experimental groups of carp was 25.0 (option 1) and 24.89 % (option 2), moisture 75.0 and 74.1 %, fat 6.5 and 5.6 %, minerals 2.8 and 2.6 %, protein 15.7 and 16.6 %. The average dry matter content in the body of carp yearlings was 21.3 (option 1) and 22.3 % (option 2), moisture 78.7.0 and 77.9 %, fat 3.8 and 3.7 %, minerals 3.0 and 2.9 %, protein 14.5 and 15.4 %. During wintering, there was a decrease in the content of dry matter, fat and protein in the body of fish and an increase in the content of moisture and minerals (ash). In general, Amur carp fingerlings have a tendency to increase the content of dry matter, fat, protein and minerals compared to carp of different origin.
