The effect of dietary probiotic Lactobacillus plantarum on nutrition performance in Siberian sturgeon (Acipenser baerii) (Huso huso)

The aim of this study was to evaluate the effects of lactobacillus plantarum probiotic in diet on some nutritional indices as well as survival rate in Siberian sturgeon (Acipenser baerii). This research were randomly designed in three treatment and one control groups in three replications with probiotic-contained diet, e.g. 107, 108 and 109 probiotic bacterial cells per gram food and the control group with no probiotic, which were treated for 60 days and then evaluated. 240 numbers of 37.666 ±1.094g of Siberian sturgeon were randomly distributed on 12 fiberglass ponds. Results showed that the used probiotic bacteria was able to strengthen the growth parameters (weight, FCR and PER) and significant increase in PER indicators and significant reduction in PER in treated with probiotics groups compared with the control group. In this study, the treatment with log8 L. plantarum indicated significant differences between all treatments and control. The survival rate in all treated and control groups were 100 percent. The results showed that the L. plantarum probiotic work as a growth promoter in Siberian sturgeon.
