Abstract

This study was carried out on 694 Clarias gariepinusand 846Oreochromis niloticus fish specimens. The fish were randomly collected seasonally, from different fish farms of El-Abbassa, Abu-Hammad, Sharkia Governorate, Egypt. They were used to investigate the prevalence of cestode parasites in C. gariepinus and O. niloticus. Parasitological examination of these fishes revealed that the, highest prevalence rates of Cestodain the fish were recorded in small fishes during summer and the lowest values were observed in the samples of the large size during winter. The study concluded that, the C. gariepinus are more attacked by internal cestode parasites compared O. niloticus. Parasites included Proteocephalus glanduligerus, Polyonchobothrium clarias and Monobothrium sp. The morphology of each species was compared with earlier descriptions, and a diagnostic character of intestinal Cestode species in this geographic region was developed.
