【 摘 要 】

ABSTRACT: This paper reviews the occurrence of cymothoid isopod parasitism in aquaculture, reports the first case of infection by a cymothoid isopod (Ceratothoa oestroides) in Turkish aquaculture, and analyses its effects on sea bassDicentrarchus labrax. Analyses revealed that C. oestroides negatively affects the weights and lengths of sea bass hosts. These effects have been previously underestimated because host age has not been accounted for. The analysis of conditionfactors as a means of assessing parasite effects is therefore likely to be misleading. Infection of fish of all ages by all cymothoid stages indicates that sea bass are not intermediate hosts but that C. oestroides has effected a complete hostshift.
