Fish farming activities often leave organic waste which can degrade the water quality. The efforts to decrease the amount of organic matter biologically is needed such as the use of aquatic animals for reducing harmful residues. The purposes of this study were to observe the dynamics of total organic matter (TOM) on Sangkuriang Catfish (Clarias gariepinus) farming and to understand the varying density of freshwater bivalve (Anodonta woodiana) to decrease the total organic matter (TOM) on the residual of Sangkuriang Catfish (Clarias gariepinus) farming activity. This study employed the survey and experimental method. The survey results, the total organic matter from inlet to outlet increases about 319% of Sangkuriang Catfish (Clarias gariepinus) farming, and for the experimental results, the best treatment of freshwater bivalve (Anodonta woodiana) surface based covered was obtained at 75% with decreasing was about 88% total organic matter (TOM) by immersion for 16 hours. © Published under licence by IOP Publishing Ltd.
