Abstract
The rapid growth of population and food shortage especially in that of animal protein origin, represent as an exaggerated problems allover the world. Parasitic infestation causes great impacts as it cause significant economic losses to fisheries through mortalities, stunting growth or damaging tissues of the infested fish. In the present study a number of 625 fish samples belonged to five species include Mugil capito, Tilapia zilli, Sparus auratus, Liza carinata and Nemipterus japonicus (each fish species=125) were collected from six governorates: El- Fayoum (Qarun lake), Ismailia, Suez (Suez canal area), Alexandria, Damietta and Port Said governorates (Mediterranean sea). Fish were examined for parasitic infestation from the beginning of November 2015 till the end of October 2016. The mean, overall % of infestation in all examined fish reached to 37.4%. Four types of parasitic infestation was recorded including Isopoda, Copepoda, Monogenea and ecto-parasitic protozoa by a mean % of 22.7%, 11.2%, 2.88% and 0.64% for Isopoda, Copepoda, Monogenea and protozoan ectoparasites respectively. The highest incidence of infestation was recorded during spring (44.86%) while the lowest incidence was recorded during autumn (26.09%). Detailed morphological descriptions of the obtained parasites were illustrated. Scanning electron microscope and serodiagnostic studies were done for isopoda species (Leveonica redmani adult and its larva.) Histopathological study was conducted for estimating the impacts of Leveonica redmani infestation on the affected tissues of Mugil capito
