    Abstract


    The objective of the study was to evaluate the hatching rate, the survival rate of fry, fingerling, juvenile and the growth rate for breeding. Experiment on hatching, nursering and rearing of two introduced common carp strains (Tata and Szavas P3) from Hungary to Vietnam was carried out from July 2019 to December 2020 at the National Freshwater Broodstock Center. The results showed that the hatching time was 61.8 and 62.2 hours for Tata and Szavas strain, respectively; the figure of the hatching rate was 91.5% and 93.3%, and the deformity rate was 1.2% and 1.3%, respectively. The survival rate of Tata fingerling was 62.5% and of Szavas P3 was 67.5%. The survival rate of juvenile Tata carp was 48.7%, Szarvas P3 carp was 53.3%. The absolute growth in length and weight of Tata carp was 6.8mm/day and 0.51 gam/day, Szarvas P3 was 6.5 mm/day and 0.49 gam/day. After 12 months of culture, the average weight and length of Tata carp was 1670.5 ± 10.2 g/fish and 50.2 ± 7.1 cm/fish, Szavas P3 carp was 1565.5 ± 10.2 g/fish and 49.3 ± 7.7 cm/fish, the feed conversion ratio values was 2.0 for Tata and 1.9 for Szavas P3 carp. The results of hatching, nursering and rearing showed that Tata carp and Szavas P3 carp can be used as genetic material for selection breeding .
