This study was carried out to evaluate the effects of different levels of dietary curcumin on growth performance and skin color of Oscar fish (Astronotus ocellatus). A total of 150 Oscar fish with initial average weight of 5.1 ± 0.25 g were randomly distributed in 15 aquariums and fed with 5 different levels of curcumin including control group without any curcumin (C0), 5(C5), 10(C10), 15(C15) and 20(C20) g curcumin kg-1 diet for 56 days. Fish fed with 5 g kg-1 diet showed significantly higher final body weight and specific growth rate compared to those fed the control treatment (P<0.05). Fish fed with 5 g kg -1 curcumin had significantly lower FCR than the control treatment (P<0.05). There were significant different in protein and lipid efficiency ratio between C0 and C20 treatment (P<0.05). curcumin concentration of skin in fish fed C20 treatment was significantly higher than fish fed C0 treatment (P<0.05). The results of the present study showed that 5 g curcumin kg-1 diet improves growth performance and 15 g curcumin kg-1 diet significantly enhances skin color in Oscar fish.
