The current study was carried out to evaluate the effects of probiotic, Lactobacillus plantarum on growth performance
and hematological parameters in Siberian sturgeon (Acipenser baerii). Fish (14.6±2.3 g) were fed three experimental diets
prepared by supplementing a basal diet with L. plantarum at different concentrations (1×107, 1×108 and 1×109 colony-forming
units (cfu) g–1) and a control (non-supplemented basal) diet for 8 weeks. At the end of the experiment, 3 fish were sampled
randomly from each tank and were anaesthetized. Then, blood samples were introduced to heparinized tubes in order to
perform performance and hematological studies. Growth performance indices were increased in fish fed the 1×108 cfu g-1 L.
plantarum diet compared to the other groups. Furthermore, the fish fed on various levels of L. plantarum significantly showed
higher red blood cell, hemoglobin, white blood cell and monocyte compared to those of the control group (P<0.05).
Although, the effect of probiotic treatments on other hematological parameters were not significant (P>0.05); but this value
was higher in probiotic supplement treatments compared to control group. These results indicated that dietary
supplementation of L. plantarum improved growth performance and hematological parameters in Siberian sturgeon.
