the highest total bacterial counts were observed in control and T1 group respectively. At day 20, the lactic acid bacteria count was higher significantly in Synbiotic treatments compared to control group (P\0.05). In all sa ling times (i.e. days 20, 40 and 60), the highest lactic acid bacteria count was observed in fish fed with 3 g Synbiotic/kg diet i.e. treatment 5 (P\0.05). In each experimental group, total bacteria and lactic acid bacteria counts increased significantly as the duration of experiment expanded. In this regard, these parameters were significantly higher at day 60 compared to day 40 and 20 (P\0.05). In conclusion, our results showed that Synbiotic (Biomin imbo) alters and stabilizes efficiently the microflora of Russian sturgeon gut towards lactic acid bacteria in a time-dependent pattern.
