This experiment was carried out to evaluate the effects of the commercial probiotic Betaplus®Ultra on the haematological profile (red blood cell (RBC) counts, haemoglobin (Hb) concentration, haematocrit (PCV), mean corpuscular haemoglobin (MCH), mean corpuscular volume (MCV) and mean corpuscular haemoglobin concentration (MCHC), glucose and total proteins) and immune response of young of the year Acipenser stellatus. In this sense, a 93- day experiment was carried out with six experimental variants (five different probiotic concentrations: C1 - 1-1.28×1013 CFU, C2 - 2.56 ×1013 CFU, C3 - 3.84×1013 CFU, C4- 5.12×1013 CFU, C5 - 6.4×1013 CFU and C0 - control group). All the trials were performed in duplicates. Based on our results, no significant differences (p>0.05) were observed in the values of RBC, PCV, MCV and MCHC, while significant differences (p˂0.05) were registered in the case of Hb and MCH. Regarding the immune response, no significant differences were registered in the values of leukocytes, lymphocytes neutrophils, monocytes and eosinophils (p˃0.05) and only, thrombocytes and basophiles were significantly influenced (p˂0.05) by the probiotic concentration. The results suggest that the probiotic Betaplus®Ultra could be used effectively as a probiotic for the use in aquaculture.
