  The morphopathological alterations of chronic cadmium (Cd) toxicity in Sarotherodon galilaeus were studied. 126 fish were used to determine 96 hrs LC50 of cadmium chloride, the obtained result was 28.3 mg/L. Forty-eight fish were used to induce chronic toxicity, twenty-four fish were exposed to 2.83 mg/L cadmium chloride for 8 weeks and other fish as control. Gills, hepatopancreas, posterior kidney and spleen were the most affected organs during chronic exposure. Eosinophilic granular cells (EGCs) infiltration and goblet cells hyperplasia in tips of primary lamellae, lamellar lifting, lamellar necrosis and Proliferative interlamellar hyperplasia with fusion in gills, hydropic degeneration and necrosis of the hepatic cells, hemorrhage and necrotic renal tubules and splenic necrosis and depletion of lymphocytes were recorded ..
