The aim of the present study was to investigate the effects of single or combined administration of dietary fermentable fiber (Vitacel (R)) and probiotic PrimaLac (R) on mucosal immune parameters, digestive enzyme activity, gut microbiota and growth performance of Caspian white fish (Rutilus frisii kutum) fingerlings. Fish were transferred to laboratory, acclimatized for two weeks and then fish (0.56 +/- 0.026 g) were allocated into 12 tanks (30 fish per tank). Triplicate groups were fed a basal diet (Control) or basal diet supplemented with fermentable fiber [Vitacel (R)] (FF), probiotic [PrimaLac (R)] (P) and combined fermentable fiber and probiotic (FF + P). At the end of feeding trial, growth performance and feed utilization parameters were significantly (P < 0.05) improved in FF, P and FF + P treatments compared control group. Evaluation of digestive enzyme activity revealed significant (P < 0.05) increase of lipase activity in fish fed supplemented diet. However, amylase, protease and alkaline phosphatase were significantly higher (P < 0.05) only in P and FF + P treatments. Furthermore, total autochthonous intestinal microbiota and autochthonous LAB levels significantly increased in fish fed supplemented diet (P < 0.05). Also, inclusion of FF, P and FF + P in Caspian white fish diet remarkably increased skin mucus immune parameters compared control group (P < 0.05). These results indicate that singular or combined administration of FF and P can be considered as a beneficial dietary supplement for early stages of Caspian white fish (Rutilus fresii kutumn) culture.
