Dissertation note: Thesis (Ph.D.) - Cairo University - Faculty of Science - Department of Zoology Summary: The present study investigated some helminth parasites infecting economically important fish species inhabiting Lake Manzala, Dakahlia Governorate, Egypt. Fish samples were collected during the period of November 2014 to December 2015 from boat landing sites and fishermen from the Lake. The collected fish species were Nile perch Lates niloticus, Striped red mullet Mullus surmaletus, Electric catfish Malapterurus electricus and African sharptooth catfish Clarias gariepinus. Prevalence and seasonal variations of parasitic infections among the examined fish species were studied. Three species of digenea parasites were recorded; these were Acanthostomum spiniceps isolated from Nile perch L. niloticus, Aponurus mulli and Bathycreadium sp. nov. recovered from Striped red mullet M. surmuletus. One species of cestoda parasite was recovered during this study which was Electrotaenia malapteruri from Electric catfish M. electricus. Two species of nematode parasites isolated; these were Dujardinnascaris malapteruri from Electric catfish M. electricus and Camallanus polypteri from African sharptooth catfish C. gariepinus. The present investigation of parasitic infections was carried out by means of morphologic and morphometric analyses by using light and scanning electron microscopy. There was a relationship between the body size (length/weight) and sex of fish host and the intensity of the parasitic infection. In addition, the relationship between pollution and parasitism. Therefore, the role of the recorded parasites as bio-indicators for water pollution was detected by determining the concentration of some heavy metals in water and sediment samples as well as parasites and fish tissues
