A total of 70 randomly selected specimens of Clarias gariepinus (Clariidae ) recovered from EL-abbasa and Met-Ghamr were examined for intestinal helminth parasites. The helminth worms recovered include two cestodes Polyonchobothrium clarias and Monobothriodes sp. two Nematode, Paracamallanus cyathopharynx and Procammalanus laviconchus. Three trematodes Allocreadium sudanensis Orientocreadium batrochoides and Astiotrema sp. There was no statistically significant difference in the infection of the male and female Clarias gariepinus; the infection rates in male and female samples were 88.2% and 96.6% respectively Parasite prevalence was related to the seasons. In this study revealed various degrees of prevalence and infection rate of parasites in the two studied areas at El- abbasa and Mit-Ghamr canals 87.5% and 66.66%, respectively (table 2) after that in this study it found significant and correlation between gastrointestinal parasite and sessions by value P<0.05 and total infected ratio 91.4% with highest ratio are in spring and summer with and lowest one is winter with 79.2% Prevalence of catfish in the two studied100% areas were determined seasonally. Finally, in the summer is the highest and the lowest in the winter as shown in histograms. The examined parasites were stained and showedby light microscopy from different views, the morphology of cestodes are in the intestine of Clarias gariepinus and characterise by the body is elongated fusiform in shape. The scolex is hexagonal rostellum armed with a crown of 26–30 hooks Nematodes isolated from the stomach and the intestine of Clarias gariepinus. It is cylindrical, yellowish brown in color with transverse annulations and the buccal capsule is consisting of two lateral valves with a large chitinous buccal cavity or pharynx behind the valves; the trident is present. Trematodes are adults have an elongated, dorsoventrally flattened body, well-developed pharynx and suckers testes in tandem, vitellarium extending from the forebody at various levels to the posterior end We recorded in this study indicated that cultured C. gariepinus like the ones in the wide are not free from gastrointestinal parasites and these parasites leading to morbidity and mortality and making the fish more susceptible to surrounding
