The aim of the present study was to examine pathogenesis, prevalence, trials for treatment and histopathological alterations of Amyloodinosis in naturally infested Asian Seabass Barramundi Lates calcarifer and Hamour Epinephelus polyphekadion in Ismailia Governorate, Egypt. Materials and Methods: A total number of 1447 Red Sea cultured Seabass (Lates calcarifer) broadstock and a total number of 53 Red Sea cultured Hamour, Epinephelus polyphekadion broadstock were collected and subjected for the study. Fishes showed symptoms of sudden death and respiratory distress besides Amyloodiniosis on gills and skin. All fishes were treated with various treatment protocols while gills of naturally infected fishes were examined histopathologically. Results: The clinical signs of infested fishes were flashing, surfacing, off food and respiratory distress. The intensity of infestation of Amyloodiniosis was more sever in Asian Seabass than Epinephelus polyphekadion while treatment of choice was copper sulphate (prolonged bath), freshwater bath and formalin consequently. Conclusion: Treatment of choice for Amyloodinium ocellatum infestation in Asian Seabass was copper sulphate (prolonged bath) followed by freshwater bath then formalin.]]>Noga, E.J.,20001st Edn.,Pages: 378Pages: 378Noga, E.J.,20102nd Edn.,Pages: 536Pages: 536Paperna, I., A.
