Results showed that dietary phytogenic supplementation improved (p<0,05) the final body weight, weight gain, specific growth rate, feed conversation ratio in compared to 0% (control)group. Fish fed diets containing 0.1% and 1% of A. vulgaris was better in feed conversation ratio in compared to 0% (control) and other concentrations (0.5%, 2.0%, 250 and 1000 mg/kg).
