Physiological and biochemical indicators of fingerlings and yearlings of carp of different breeds from the collection herd

Scientific developments are actively used to improve the efficiency of the fishing industry. One of the new directions in breeding and breeding is the assessment of the quality of fish stocks by biochemical blood tests of fish. Blood as the internal environment of the body reflects any changes in the state of health, since it is in it that many metabolic reactions take place. Thus, studies of the blood composition of fish are in great demand in fish farming. Much attention is paid to the study of the concentration of biochemical substances in the blood of fish, as this allows you to quickly and accurately assess the quality of the fish stock. Fish are poikilothermic, therefore their physiological state depends on the environment. Investigations of the biochemical composition of fish blood were carried out in the selection and breeding fish farm “Isobelino” and in the laboratory of the institute. As a result of annual studies, it was found that the concentration of blood components in different fish species is different. This fact can explain the difference in the survival rate of different breeds, which were kept in the same conditions. As a result of comparing the content of total protein, cholesterol and glucose in the blood serum of underyearlings and yearlings of collection carp breeds of Belarusian and foreign selection grown under the same conditions, changes in physiological and biochemical parameters were established. The results of the study revealed the advantages of layering a mixture of Mirror Isobelinsky carp among Belarusian lines and Sarboyan carp among imported breeds.
