The method used was experimental method and R A L one factor with 3 level of treatments. The treatment with stocking density of 10. 15 and 20 taiwanese clam {Anadonla woodiana Lea) respectively. The result indicated that different stocking density of taiwanese were have significantly effect on water quality (NH3),.growth rate and survival rate of silais {Ompok hypopthalmus). The best result was achieved by 20 taiwanese clam (Anadonta woodiana Lea). Total absolute body weight of silais was 9.53 grains, daily growth rate o f 2,18 % and survival rate of 100%.
