Fry of common carp (Cyprinus carpio) were chronically exposed to 2.5 mg Cd/L alone and in combination with 1.0 mg KMnO{sub 4}/L or 2.0 mg CoCl{sub 2}/L or a dietary supplement of vitamin B complex at the rate of 26.5 mg/100 g food. Cadmium induced edema of primary and secondary gill lamellae, nuclear swelling, and necrosis and hypertrophy of epithelial cells of the secondary gill lamellae. Similar or more severe lamellar damages were observed with exposure to cadmium together with potassium permanganate and to cadmium together with cobalt chloride. Potassium permanganate alone was also found to produce severe edema of the gill lamellae. A dietary supplement of vitamin B complex reduced the cadmium-induced gill damages and resulted in a normal gill in exposed fish. 24 refs., 4 figs., 1 tab.
