Warrapong Nalinanon and Saichon Lerdsuwan

ABSTRACT: An experiment was undertaken to obtain the optimum level of coconut and A. mangium meal of juvenile nile tilapia. The experimental design was CRD at 6 treatments 3 replications and 18 experimental units as 20 fish/unit. Treatments was mixed feed contained 6 level of coconut and A. mangium meal as 0, 20/0, 0/20, 5/15, 10/10 and 15/5 % of practical diets pellet feed. Fish with the initial average weight 0.2 g. They were fed for 12 weeks to nile tilapia fingerling stocked in 18 plastic tanks (200 liters) set up to recirculation system. Results indicated that final weight, weight gain, ADG, FCR and FE were the best in treatment 1(control) significant different (p<0.05) with other treatment, whereas the best growth of supplement coconut and A. mangium meal group was gained in 10/10% coconut and A. mangium meal in diet.
