The present study performed to examine effect of the herbal supplement, including Zataria multiflora and Satureja khuzistanicapowder (0(H0), 2(H1), 5(H2), 8(H3) and 13 (H4) percent per kilogram) on growth indices, survival rate, and biochemical parameters of blood in common carp. Fish were fed with experimental diets for 60 days. The result indicated that the use of different levels of the herbal supplement significantly increase survival rate compared to control group (P<0.05). The highest final weight gain and specific growth rate were observed in the treatment containing H3 (P<0.05). The best factor for food conversion was observed in H3 (P<0.05). The highest and lowest condition factor were obtained in H3 and H0, respectively (P<0.05). There was no difference between the amount of glucose in fish fed with herbal supplement and that of the control group (P<0.05). The highest value of total protein was measured in fish fed diets, containing 13 g of herbal supplement (P<0.05). The cholesterol and triglyceride levels decreased with increasing herbal supplementation (P<0.05), so that the lowest amount of these factors was observed in the treatment of 8 g of herbal supplement (P<0.05). The amounts of C3 and C4 factors increased with supplementation of herbal and showed the highest amount in H4 treatment (P<0.05). The results of the approximate composition of carcasses of fish showed that protein and carcass ash values in plant supplement treatments were significantly higher than control (P<0.05), and the highest values were observed in H4 treatment (P<0.05), however, no significant difference was found of fat and carcass moisture values among treatments and control treatments (P>0.05). It can be suggested the adding 13 g of herbal supplement per kilogram of carp to improve performance growth, nutrition and biochemical indices in this fish.
