This study was undertaken to evaluate the effects of Immnowall on feed intake, weight gain, food conversation ratio, specific growth rate, total length and survival of juvenile Kutum, Rutilus frisii kutum. For this purpose, 300 fish were stocked in three replications at the VENIRO tanks and fed twice daily by 0.5, 1 and 1.5 g/Kg of Immnowall for 8 weeks. Results showed that growth factors including: weight gain, specific growth rate, growth rate, feed conversion ratio and body weight index for fish administrated by 0.15 percent Immnowall showed a statistical significant differences (P<0.05) by control. Protein rate increased in probiotic treatment ( 4,5 and 6 with 0.05, 0.1 and 0.15 percent Immnowall in diet )of carcass analysis and showed a statistical significant differences (P<0.05) by control. Moreover, fish fed by 0.05 percent Immnowall and 0.15 percent Immnowall multienzyme showed a significant difference (P<0.05) in higher survival rate than control.
