Evaluation of the reproductive indexes of carp (Cyprinus carpio Linnaeus, 1758) at the PJSC “Khmelnytskrybhosp”
Abstract
Purpose. To carry out the analysis of exterior and reproductive indexes of the brood common carp of the commercial farm PJSC “Khmelnytskrybhosp”. Methodology. Methods generally accepted in fish selective breeding and farming have been used for the scientific works. Findings. Pond fish farming, as the traditional form of fisheries, is one of the main sources of table fish products, the task of which is the rearing and cultivation of valuable fish breeds in ponds. Successful fish farming development is possible only with the use of complex intensification of production. One of the main components of intensification in fish farming is the well-established selection and breeding work aimed at qualitative improvement of breeding facilities, namely: the selection of new breeds and the creation of highly productive breeding stocks of fish and their rational use. The results of production of commodity fish depend on the provision of the fish farm with fish seeds and their quality. Evaluation of the exterior and reproductive indexes of the commercial stock of brood Antonino-Zozulenetskiy common carps at the PJSC “Khmelnytskrybhosp” has been carried out for purpose of the organization of selective breeding works for improving of the growth rate, exterior, survivability and fecundity of cultured fish. Originality. This analysis will be used as a parameter of the value of Antonino-Zozulenetskiy common carp in their commercial stocks of fish farms of the PJSC “Khmelnytskrybhosp” for forming selection nests and carrying out of the selective breeding works at these farms. Practical value. The results of the work will contribute to the selection and forming of the brood stocks of Ukrainian common carp strains, which are characterized by high growth rates, exterior, typical appearance, survivability and fecundity.
