A total number of 400 African catfish, Clarias gariepinus were collected alive from different freshwater fish farms at Sedi- Salem and El-Ryad districts in Kafr El-Sheikh Governorate, to investigate the digenetic trematodes infecting fish as a final host.

The isolated seven flukes were identified as: Emoleptalea sp., (from intestine), Phyllodistomum sp., (from kidney) as new records, Orientocreadium batrachoides, Orientocreadium lazeri, Astiotrema reniferum, Paramacroderoides echinus (from intestine) and Eumasenia aegypticus (from stomach).
