HISTOPATHOLOGICAL CHANGES IN LIVER AND KIDNEY OF CATFISH, CLARIAS BATRACHUS EXPOSED TO ALUMINIUM

The present study was carried out to analyse the histopathological changes in freshwater catfish Clarias batrachus (Indian magur) in the presence of aluminium. Fishes were exposed to aluminium with three different concentration level (8.75μg, 17.5μg, 35μg) for 96 hours in water. During this period fishes were fed with Laboratory prepared food. After 96 hours, fishes were taken out and sacrificed. The tissues like liver and kidney were removed for study. Histopathological changes like loss of hepatic cells in liver of fish, cytoplasmic vacoulation, and loss of glomerular structures in kidney of fish were observed. It was noticed that the histopathological alterations were found to be dose dependent in the tissues, changes were more pronounced with higher concentration of aluminium chloride like nacrosis of hepatic cells at concentration 35μg/l was observed in liver. In the same way under high concentration of aluminium clustering of cells were observed in kidney
