This experiment was conducted to apply coconut meal in big oui diet at the rate of 0, 10, 20 and 30 percent. Four treatment groups with four replicates of big oui fingerlings with an initial weight of 5.674 gm/fish were stocked in flow-through-water concrete tanks. Duration of the experiment was 12 weeks. Analysis of the experimental results indicated that weight and length of fingerlings fed with all diets did not differ between treatments. Application 30, 20 and 10 coconut meal gave the yield in the ranking order from high to low. Concerning the total weight of the fish different diets resuited in non significant differences while the 20 percent diets gave the highest total weight. The 10 and 30 percent did less perpectively. Water quality parameters (dissolved oxygen, free carbon dioxide, hardness, pH and temperature) did not differ among all treatments.
