Supplemental amino acids and organic acids in diet of white shrimp was conducted in CRD with 3 treatments and each of 5 replications. Diet of 32 percent CP containing 20 percent Fishmeal (FM) as control (treatment1), supplemental amino acids 0.2 percent and supplemental organic acids 0.1 percent in diet containing 10 percent FM as treatment 2 and 3, respectively. The result showed that there were not significantly difference (p GT 0.05) on growth performance in term of weight gain, average daily gain, survival rate and feed conversion ratio (FCR). Percentage of tail (edible flesh) in group of shrimp fed diet supplemental amino acids tended (p=0.08) to be higher than the other groups. Total hemocyte count in group of shrimp fed diet supplemental amino acids and supplemental organic acids tended (p=0.07) to be higher than control. Vibrio spp. Counted from shrimp fed diet supplemental amino acids was higher (p LT 0.05) than the other groups. Hepatosomatic index in control was higher (p LT 0.05) than the other groups. Therefore, supplemental amino acids and organic acids in diet of white shrimp which composed of 10 percent FM demonstrated the equivalent growth performance as diet composed of 20 percent FM
