This study was performed to evaluate the effects of two types of powdered extract echinacea (Echinacea purpurea) and garlic (Allium sativum) on antioxidant capacity of farmed beluga Huso huso fry during a two-month period. For this purpose, 210 fry with an average weight of 27.74 ± 0.26 g were randomly placed in 21 500-Litre fiberglass tank in seven different treatments with three replications, including a control group and three experimental groups of different amounts of Echinacea powder extract (250, 500 and 1000 mg/kg) and three experimental groups of different amounts of garlic powder extract (250, 500 and 1000 mg/kg) were studied for 8 weeks. At the end of experiment, the amount of catalase, GPX, SOD and MDA enzymes was meseared in six fish per treatment. The amount of catalase, SOD and MDA in the blood serum in the treatments increased compared to the control. The amount of catalase in treatment 5 was significantly higher than other treatments and the lowest amount of catalase was observed in control and treatment 1. The amount of SOD in treatments 2, 3, 5 and 6 was significantly higher than other treatments and the lowest amount of SOD was observed in the control. The amount of MDA in treatments 3, 5 and 6 was significantly higher than other treatments and the lowest amount of MDA was observed in the control. The amount of GPX in fish blood serum in treatments 6, 5 and 4 was significantly higher than other treatments and the lowest amount of GPX was observed in treatments 1, 2 and 3. Based on the observed results, it can be concluded that the oral administration of the powdered extract of echinacea and garlic has a positive effect on the antioxidant capacity of farmed beluga fry.
