The present study was carried out to investigate the endoparasitic helminthes infecting two host fish species, Bagrus docmac and Malepterurus electricus. Fish was collected from three water bodies at Menoufiya Governorate namely, Bahr Shebeen Canal, Albagoreya Canal and Sabal Drainage Canal. Out of 354 fish examined, 89% were found infected with parasitic helminthes. The relationship between sex, length, weight and age of the examined fish, and the prevalence and mean intensity of helminth infections were studied. The present study revealed the presence of four trematodes: Acanthostomum spiniceps, Acanthostomum absconditum, Haplorchoides cahirinus, and Phylldistomum spatulaforme; two cestodes: Corallobothrium solidum, Electrotaenia malepteruri; and three nematodes: Spinitectus allaeri, Procomallanus laeviconchus, and Capillaria yamaguti.
