Younis,N. A.
In this study, investigated the relation between the parasitic protozoal infection rate and water pollution in locations from which fishes were collected. In this study, the infestation rate of different protozoal diseases in wild freshwater fishes namely: Oreochromis niloticus and Clarias gariepinus was 66.2% and 49.52% respectively. These fishes were collected from different areas in Nile River in Giza governrate. The results proved the occurrence of many protozoa including internal and external protozoa. The infestation rate with these parasites was varied with seasons and species of fish. It was noticed that highest rate of infestation was in summer season followed by spring, autumn and finally winter. Histopathological studies revealed inflammatory changes in the infected tissues.
