The purpose of this study was to study morphophysiological signs in fish from the brood stock of carp grown in the educational and experimental farm of KSTU. The object of the study was fish from the senior repair group entering the breeding stock for the first time. The research was carried out during the spring fishing of winter repair ponds. Clinically healthy individuals with no abnormalities in the development of the body, fins and head were selected for the representativeness of the studies. Morphophysiological indicators of fish were evaluated using the method of morphophysiological indicators. After determining the exterior and meristic features of the fish, they were opened, determining the mass of internal organs and the length of the intestine. Based on these studies, the indices of internal organs and intestines were calculated according to standard methods. The value of the index of intestinal length in female carp averaged 158.77, and in males 198.75%. The ratio of the anterior part of the swim bladder to the posterior is 1.13 in females, and 1.12 in males. The study of organ indices showed that for females the spleen index was 0.76, for males 0.75%; the gill index was 4.34% for females, 4.13% for males; the liver index is 4.76 and 3.05%, respectively. The gonadosomatic index (GSI) for female carp averaged 50.32%, for males 26.59%. Thus, when analyzing morphophysiological indicators in the first-time spawning males and females of carp, it was found that in terms of the index of intestinal length and the relative length of the intestine, as well as the ratio of the chambers of the swim bladder, the producers of carp grown at the KSTU g are close to “wild” carp or carp. This is probably the result of the specific growing conditions at this enterprise. All values of other morphophysiological indicators in the studied carp producers can be considered satisfactory.
