Abstract
The experimental fish exposed to different graded concentration of toxicant (copper chloride), exhibited abnormal behavioral response. During the exposure time CuCl2 treated fish initially showed rapid movement faster opercula activity, surfacing and gulping of air. The study was assess the effect of copper chloride on histopathology of liver in the fresh water fish Clarias batrachus. The fish were dividing in 5 groups. After exposure to 1/5 of sub lethal concentration of copper sulphate, the tissue like liver of the fish Clarias batrachus showed various degenerative changes after 7, 14, 21 and 28 days. The degenerative histopathological change observed in the liver are remandable in the copper chloride treated fish.
