Abstract
The aim of this study was evaluation the effects of supplemented diets by levamisole and Echinacea purpurea (Moench, 1794) extract on growth and reproductive parameters in angelfish, Pterophyllum scalare (Lictenstein, 1823). 54 Uniform angelfish (average weight 3.8±0.29 g) were selected. The fishes were fed by three diets which included commercial extruder diet (control), commercial extruder diet supplemented by 0.25 ppt levamisole (T1) and commercial extruder diet supplemented by 0.25 ppt Echinacea purpurea extract (T2). The experiment was conducted for 3 months. The weight gain in T2 was significantly higher than other groups (p<0.05). There was no significant difference (p>0.05) in fecundity and hatching rate among groups but the best survival of yolk-sac absorption period was found in group fed supplemented diet by Echinacea extract (p<0.05). This study indicates that growth performance can be improved by dietary Echinacea extract supplementation and larval survival can be promoted by it.
