Abstract
Acute toxicity bioassay of copper (Cu) for the freshwater catfish, Clarias batrachus was conduct for evaluation of the toxicity. The 96th LC50 values recorded for Cu was 15 ppm, 29 ppm and 35 ppm respectively. The result of this study indicate that the order of toxicity of this heavy metal is Cu in short duration acute toxicity experiments. The toxicity was found to be dependent on dose and duration of experiment for heavy metal.
