The aim of the present study is to determine lethal concentration for 50% mortality of sugar mill effluent to fresh water fish Tilapia mossambica for 24to 96 hours using bioassay method. The LC50 values of the prepared concentration for 24, 48, 72 and 96 hrs were found at 11, 10.5, 10.1 and 9.5% respectively. At this concentration, erratic swimming, jerky movement, rapid opercular movement leaping out of water and thick mucous covering over the whole body surface were observed during experiments.
