| Abstract: | Abstract. In a parasitic survey of gilthead sea bream, Sparus aurata L., cultured in different systems in Spain, eight protozoan species were found. Ectoparasites included two ciliates ( Trichodina sp. and a Cryptocaryon -like species), one dinoflagellate ( Amyloodinium sp.) and the zooflagellate Ichthyobodo sp. Endoparasites were represented by members of the Apicomplexa ( Eimeria sp.) and Myxosporea ( Polysporoplasma sparis. Ceratomyxa sp. and Leptotheca sp.). Ichthyobodo sp., Eimeria sp., Ceratomyxa sp. and Leptotheca sp. are reported for the first time in S. aurata. Amyloodinium sp. and Ichthyobodo sp. were associated with outbreaks of disease in larval and juvenile fish. Data on prevalence and intensity of infection and the location in the host are provided. The potential importance of these protozoan parasites for gilthead sea bream culture is discussed. |
