This study was carried out to evaluate the effects of Macrogard and Spirulina on some hematological parameters of juvenile farm-raised stellate sturgeon. This study was designed using a completely random plan containing 0% (control), 0.1% Spirulina (M0S1), 0.1% Macrogard (M1S0), 0.1% Macrogard and 0.1% Spirulina (M1S1) and 0.5% Macrogard and 0.5% Spirulina (M5S5) in 5 treatments with 3 repetitions. A total number of 700 stellate sturgeon fish (average weight of 87.56±1.06 g) were fed during 12 weeks. At the end of trial, the blood samples were collected and haematological parameters including leucocyte count (WBC), erythrocyte count (RBC), haematocrit (HCT), erythrocyte sedimentation rate (ESR) and the white blood cell differential were measured. The maximum level of WBC and HCT were observed in M5S5, while the lowest level of ESR was seen in M5S5 (p<0.05). The population size of RBC was significantly higher than control group. The highest population size of lymphocyte (75.08+2.10%) was measured in M5S5 and the also highest population size of neutrophil was observed in M1S1 and M5S5 (p<0.05). Therefore, using Macrogard and spirulina, each at 0.5% in stellate sturgeon diet, significantly hematological indices, population size lymphocytes and neutrophils.
