This study was conducted to investigate the effects additive cinnamon and coriander powders on growth, feed utilization, survival rate and body chemical composition, of common carp Cyprinus carpio L. for 56 days in class aquaria. 210 fish with initial weight 8±0.5gm\fish .Fish were acclimatized for 21 days before starting the feeding experiment to acclimatize the fish to the aquaria environment. Fish fed dietary cinnamon and coriander powders at levels of 1.25, 1.5, 1.75% against those fed diet without medical plant as control. Analysis of data showed there were significant differences (P≤ 0.05) for live body weight, weight gain, feed conversion ratio and protein retention. There were no significant differences among experimental diets with control for specific growth rate, survival rate, food consumption and protein consumption criteria. The addition of cinnamon and coriander powder resulted in a significant superiority (P≤ 0.05) in protein efficiency ratio and protein productive value, which depended on the added percentage of these two types of medicinal herbs. The percentage of dry matter and raw protein increased, while the percentage of fat decreased, and the ash content did not affect with the use of adding cinnamon and coriander powder in edible portion of experimental fishes.
