Morsy M.G., Protasowicki M., 1990. Cadmium bioaccumulation and its effects on some hematological and histological aspects in carp, Cyprinus carpio L., at selected temperature. Acta Ichthyol. Piscat. 20 (1): 105-116.

Cadmium bioaccumulation and its effects on the changes of some hematological parameters in carp, Cyprinus carpio L., was studied. Carp was exposed 24 h to acute concentration of cadmium (0.5 mg Cd/dm3 water) at 27°C. Particularly the greatest accumulation of cadmium was in gills, kidneys, alimentary canal, hepatopancreas, and with lesser degree in spleen and vertebral column; while in skin and muscles accumulated only low levels of cadmium. Hematologically, cadmium bioaccumulation significantly raised erythrocytes count, hemoglobin content, hematocrite value and blood glucose, but decreased leukocytes count in comparison to control samples. Histologically, cadmium caused pathological alterations in the gill filaments and respiratory lamellae, hepatopancreas and kidney but did not affecting the skin. In addition, cadmium disturbed the metal contents (Cu, Zn, Fe and Mg) in organs in which it accumulated.
