Abstract :

The present study that was done in winter 2008 in shahid Mottahary Aquaculture Center, the effect of Saccharomyces cerevisiae PTCC5052 was investigated as a probiotic increasing of survival and enhancing the growth of Rainbow trout larvae. ????, 8400 yolk sac larvae were devided in to 4 tratments in 3 replicates. The ratio of yeast in 3 treatments were 106, 107, 108 yeast per geram food of fishes for A,B,C treatments, respectively. Mean survival for treatments were 87.8% in control group , 92.8% in treatment A, 93% in treatmen B and 95.4% in treatment C. After analysis of data, in comparison to control group, significance difference was observed only in treatment C (P<0.05).
