Abstract
The research was conducted from April until June 2012 at Aquacukure
Technology Laboratory Fisheries and Marine Science Faculty o f Riau University.
The aim of the research was to improve water quality through the biotllter using
taiwanese clam {Anadonta woodiana Lea) on culturing system of silais to increase
the growth and survival rate of silais (Ompok hypopthalmus). 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%.
