TOXIC STRESS OF CHROMIUM ON HISTOPATHOLOGY OF KIDNEY IN FRESH WATER TELEOST FISH CATLA CATLA

Dr. P. Ranganatham

Abstract :

 The fingerlings of fresh water teleost fish, Catla catla when exposed to different sublethal concentrations of chromium for a different periods1, 8, 16, 32 days of time ought changes in the structure and morphology of the osmatic organs such as kidney. In trivalent chromium exposed fish, a few pathological changes were seen during the initial days of exposure and then structural reorganization observed in later days of exposure, The degenerative changes observed in the kidney of the fish exposed to the sublethal concentration of hexavalent chromium were, Dilated Bowman’s capsule with reorganization, indistinct capillary structure in the shrunken Glomerulus, tubular destruction, vacuolation in the cytoplasm of the tubular cells and a clear increase in periglomerular space and loss of cell architecture and degeneration of cell nuclei were observed.
