Histopathological Alterations in the Liver, Gills and Kidneys of Fish Labeo Rohita After the Exposure of Endosulfan and Lindane

Pesticides have become an important tool of modern agriculture to protect standing crops, stored grains and human belongings from pests and also help in preventing diseases. As a whole or in residual form, these pesticides make their entry into the aquatic ecosystem and pose a serious threat to the aquatic organisms in general and fishes in particular. To evaluate the effects of selected pesticides (Endosulfan and Lindane), histological studies on liver gills and kidney tissues of fish, Labeo rohita, were investigated. On exposure to the above said chemicals, liver recorded congestion, hemorrhages, micro to macro-vacuolar degeneration of hepatocytes, mononuclear cell infiltration, bile duct hyperplasia, necrosis and periductular fibrosis. While coagulative necrosis of hepatocytes was recorded during Endosulfan exposure only. Gills recorded multifocal necrosis of lamellae, congestion and hemorrhages of blood capillaries and fusion & atrophy of secondary lamellae after exposure to Endosulfan and Lindane. Kidney showed mild congestion and hemorrhages of blood vessels with mild tubular degeneration, diffused swelling and degeneration of proximal and distal convoluted tubules, narrowing of renal tubules and loss of hemopoetic tissue. The physic-chemical parameters of water remained in the optimum limits during the experimental period. Keywords— Endusulfan, Gills, Lindane Hepatocytes, Labeo Rohita, Hepatocytes, Kidney.
