Abstract	The discharge of untreated textile industrial effluent into freshwater bodies poses a significant threat to aquatic biodiversity. This study evaluated the acute toxicity of textile effluent collected from the Bandi River, Pali, on the freshwater fish Clarias batrachus. Bioassays were conducted using six graded concentrations (0%, 10%, 30%, 50%, and 70%) over an exposure period of 96 hours. Mortality data were analyzed using probit analysis to determine Median Lethal Concentration (LC50) values. Results indicated that LC50 values decreased with increasing exposure time, recorded as 56.20%, 28.80%, 22.40%, and 16.60% at 24, 48, 72, and 96 hours, respectively. The safe concentration was determined to be 32.90%. The study concludes that textile effluent is highly toxic to C. batrachus, with mortality being both concentration and time-dependent.
