Effects of Probiotic, Pediococcus acidilactici, on Growth and Survival of Kutum, Rutilus kutum Fingerlings

In the present study effects of different levels of probiotic Pediococcus acidilactici, on growth performance and survival rate of Rutilus kuttum were investigated. Fingerlings Kutum with mean weight of 1±0.235 g were reared for 8 weeks in 500-l fiberglass tanks (15 fish per tank) with 4 diet treatments (with 3 replicates for each treatment). Treatments were included 1× 109 , 2:1×109 , 3× 109 CFU kg-1 dry food and without probiotic (control). At the end of the study, specific growth rate (SGR) and survival rate (SR) were higher in treatments supplemented with probiotic compared to control and its different were significant with together (p
