Embryonic development of cultured form of common carp (Cyprinus carpio) and silver carp (Hypophthalmichthys molitrix) was studied; objects were introduced to Uzbekistan (Central Asia) in the early 1960s. More than 10 generation changes were taken place in local conditions. Artificial reproduction by using gonadotropic stimulation of ripening and eggs incubation is main method to provide reproduction of the species in the country. Embryonic development passed normally. A larva hatching occurs 3 days after fertilization for common carp and 32 hours for silver carp at water temperature 22-23oC, transition to exogenous feeding – 7 days for common carp and 5 days after fertilization for silver carp.
