Abstract
    The biological material used for this work was represented by breeders of Romanian cultured carp (Cyprinus carpio) variety without scales Moldova - Podu Iloaie, of different ages exploited and reproduced in the conditions offered by fish farms in northern Moldova. In this sense, at the beginning of 2019, 6 experimental groups of carp breeders of different ages were formed, which were monitored throughout the period of naturally directed reproduction, in two fish farms in Iași County. The present paper aims to make a comparative analysis of the results obtained from the natural directed reproduction of carp (Cyprinus carpio, Linne, 1758) variety without scales Moldova - Podu Iloaie, from the 6 experimental groups. In this sense, it was determined the weight and some body indices in carp breeders, the determination of female prolificacy, the survival rate of the pre-developed brood obtained from breeders in the six groups.
