Applying herbal food attractant, in addition, to encourage fishes to food intake tends to promote growth indices and also stimuli the immune system and finally decreases antibiotic consumption and environmental tension. In this survey, the effects of Allium sativum, Oregano vulgare and Mentha piperita extracts on growth indices, survival rate and health indicators of reared giant sturgeon (Huso huso) juvenile were conducted. Sixty specimens of Huso huso with an average weight of 360 ± 2.25gr. Were supplied from Research Centre of Dr. Keyvan, stocked in 12 tanks with 350 liters water volume, four treatments with triplicates (5 specimens in each replicate) designed for this experiment. Fishes fed by 1.2% of biomass 4 times daily by extruded food supplement including 0.1 gr/kg of Mentha piperita and 0.1 gr/kg Mentha pulegium and 0.5 gr/k Allium sativum extracts during a 60 days experiment. Biometric measurements were done every 15 days, the mean value of GR, SGR, FCR, K factor measured based on standard methods. Immune parameters evaluated by blood samples. FCR of Mentha pulegium and Mentha piperita contained diets were significantly lower than Allium sativum treatment (P<0.05). The mean value of GR, SGR and K factor in Allium sativum treatment were significantly low (P<0.05) while these factors in Mentha piperita and Mentha pulegium treatments were significantly high (P<0.05). Results showed that the number of white blood cells, red blood cells, hemoglobin, hematocrit, mean corpuscular volume (MCV), mean corpuscular concentration (MCH), the average MCHC, neutrophils, lymphocytes, eosinophils, lysosomes, IgM and ALP in Huso huso blood had no significant difference in all treatments (P>0.05). Levels of ALT and AST in blood serum of fishes fed diet contained Allium sativum were significantly higher than other treatments (p<0.05). Overall, the use of 0.1 gr/k of the extracts of Mentha piperita and Mentha pulegium in the diet improved growth indicators, while no growth indices improvement observed by using 0.5 gr/k of Allium sativum extract. None of the treatments had effects on the non-specific immune (cellular or humoral immunity) abilities. Although no statistical difference observed in the survival rate of treatments. According to the results, priority use of herbal additives for juvenile Huso huso is Mentha pulegium, Mentha piperita and Allium sativum.
