The efforts of fishermen fishing in lower River Benue in Makurdi, Benue State, Nigeria was employed to collect samples of Clarias gariepinus juveniles with length range of 14.20cm to 16.50cm and weight range of 28.40g to 32.20g. After proper acclimatization and trials, the fish samples were exposed to varying concentrations of two detergents , Omo and Klin. The concentrations of klin used were 12, 16, 20, 24 and 28mg/L while that of Omo were 16, 20, 24, 28 and 32mg/L. A control experiment was also set up. After static renewal bioassay and observations at 24, 48, 72 and 96 hours, the 96 hour LC50 of Klin on Clarias gariepinus was determined to be 18.28mg/L (upper and lower limits of 20.60mg/L and 16.22mg/L respectively) while that of Omo was 23.69mg/L (upper and lower 26.16mg/L and 21.46mg/L respectively). There was no mortality in the control. It was concluded that Klin is more toxic in the aquatic environment than Omo and that detergents should not be released indiscriminately into the environment.
