Crayfish with initial body weight of 1.37±0.13 g were randomly stocked to experimental tanks. Four different onion powder levels in ratios of 10, 20, 30, and 40 g/kg were added to the formulated experimental basal feed and a control group was fed with basic feed. At the end of the study, final body weight, weight gain and survival rate improved with increasing in onion powder inclusion groups and they showed significantly difference compared to the control. In conclusion, 20-30 g/kg onion powder can be recommened used as an effective dietary supplement for red swamp crayfish culture.
