Abstract

This study was investigated the effect of supplemental of Saccharomyces cerevisiae, in diet, on the reproduction performance of Common carp (Cyprinus carpio). Broodstock were fed either a non-suppemented diet (control diet, CD) or a yeast supplemented diet (supplemented diet, SD) for 70 days before spawning (artificial spawning). The results revealed that the mass of eggs and Egg Wight Index Percentage (EWIP) were higher (p<0.05 and 0.01) in group yeast supplemented diet compared with the control group. The mean fertilization and the percentage of live embryos after 48 hrs were not significantly in all the treatments. The return and economic efficiency were higher (0.01) in group 3 (500g/ton) compared with the other groups.

Key words: Saccaromyces cervisiae, Common Carp (Cyprinus carpio), Reproductive Performance, nutrition.
