Abstract

This study was carried out to detect prevalence and seasonal variation of external parasites affecting freshwater fishes. Three hundred and thirty Oreochromis niloticus and 140 Clarias gariepinus were collected from three different ecosystems at Kafr El Sheikh province. Obtained results revealed that, the highest infection rate was recorded among O. niloticus followed by C. gariepinus. Also, seasonal dynamics among the examined O. niloticus were recorded.The isolated ectoparasites among examined fishes were Cichlidogyrus tilapiae, Cichlidogyrus aegypticus, Cichlidogyrus cirratus, Quadricanthus aegypticus, Macrogyrodactylus clarii, Trichodina centrostrigeata, Trichodina rectinucinata, Chillodinella hexastica, Ichthyophthirius multifillis, Henneuguya branchialis, Lamproglena monody, Ergasilus sarsi and Copepodit stage (2nd stage) of Lernea cyprinacea.
