The reproductive characteristics of crucian carp producers, the growth of hybrids and pure types in the embryonic and postembryonic period have been studied. The valuation of crucian carp has been done, that allowed them to be attributed to the first class. It was found that some differences on the exterior were observed on the volume of ejaculate, and on the working absolute fecundity of crucian carp. These indicators were higher in silver crucian carp than gold crucian carp. Breeding performance had great influence on the development of the young crucian carp types. Hybrid young crucian carp fry had higher weight than pure types of crucian carp that live in ponds with different feeding conditions.
