Many plant species are used to catch fish by giving them plant extract, and if the extract is poisonous to fish, it is known as a piscicide. Madhuca indica is a piscicidal plant, and the extract of the dry flower of this plant is toxic to fishes after exposure to the extract i.e. LC50/5 at regular intervals of 24 hours, and the histological effect on the liver of the freshwater fish Channa orientalis was studied. Hepatic cells are loosely arranged or compactly arranged, central vain is inflated and dilated, portal vain is bordered by coagulated blood, and the hepatic artery is decreased or swollen, and other abnormalities seen in the liver. Gills showed severe lamellar fusion, hyperplasia, hypertrophy and epithelial lifting, swelling and deformed lamella, in some parts sloughing off and curving of lamellae was also observed. Kidney showed Necrosis, epithelial tubuli contraction, glomerular injury, reduction of renal hematopoietic system, tissue damage, glomerular constriction and proliferation of connective tissue. Fish have been found to be poisoned by the extract.
