Abstract: Amyloodinium ocellatum, a dinoflagellate which causes one of the most serious diseases of marine aquaculture. It is one of the most important of the ectoparasitic protozoa. In this respect, the present study was aimed to investigate the occurrence of Amyloodiniosis among cultured European seabass (Dicentrarchus labrax) fishes. The present study was aimed to investigate the occurrence of Amyloodiniosis among cultured European seabass (Dicentrarchus labrax) fishes. This work was carried out on 1065 European seabass fishes of different life stages (546 fry-222 fingerling and 78 adults) which were collected in different seasons of the year. Cultured fish were collected from different marine farms in Egypt during the period from April 2015 to April 2016 and subjected to full clinical parasitological and histopathological examination studies. The interaction between the environmental stressors and Amyloodinium ocellatum Infestation were also analyzed. The ecological factors that affects Amyloodiniosis occurrence also be discussed in the present study. As well as examining the antiseptic activity of hydrogen peroxide against the ectoparasitic protozoan A. ocellatum as a preliminary trial for treatment. It was cleared that, the treatment with hydrogen peroxide with a concentration 20% in two doses 100ppm & 200ppm for two weeks was more effective, safe and excellent and that was confirmed through lower the load of parasitic infestation and recovery of infested fishes with no mortalities were recorded at the end of the treatment trial.
