The success of the fish eggs incubation period is conditioned by the quality of the biological material, the environmental conditions and, last but not least, the device in which the incubation is carried out. At Research and Development Station for Fisheries Nucet (S.C.D.P. Nucet), the incubation of eggs obtained through artificial reproduction of the silver carp Hypophthalmichthys molitrix (Valenciennes, 1844) is carried out in the "Carafa" type incubator. It had some disadvantages, which is why certain improvements were made. After their implementation, an increase in efficiency was observed, such as: reduction of labour, improvement of work quality, obtaining higher indices at the hatching percentage of 92.6%, the survival percentage from hatched larvae to 3-5-day old larvae of 91.3%, as well as the survival percentage from embryonated eggs to 3-5-day old larvae of 84.5%. Thanks to the innovative modifications made to the "Carafa" type incubator, they were implemented and are currently used successfully in the artificial reproduction station within the S.C.D.P. Nucet.
