RESPIRATORY BEHAVIOUR OF CLARIAS BATRACHUS, LINN. DURING EXPERIMENTAL PLUMBISM

Cat Fishes like Clarias batrachus, are gifted with an accessory respiratory device that makes them adapted to pollute or oxygen deficit water bodies. They regularly visit to the surface to engulph air. In the present piece of study, the fish was exposed to various sub-acute and chronic concentrations of Lead acetate. They were monitored constantly for respiratory behaviour. The results revealed enhanced surfacing decreased opercular beat.
