Abstract: South Sea Pearls are produced by the oyster Pinctada maxima, and Indonesia is a major global producer, supplying 43% of the world’s demand. This study identifies protozoan parasites infecting pearl oysters (Pinctada maxima) at Lombok Marine Aquaculture Development Center, Sekotong, West Nusa Tenggara. Pearl oyster samples were collected through simple random sampling from the longline, in a total of 106 samples. The examination was conducted using native and histopathological methods with Hematoxylin Eosin staining. Of the 106 samples examined, Perkinsus protozoan parasites were found in 8 samples, with a prevalence of 7.5%. Water quality parameters, including temperature (27-30°C), salinity (31-32 ppt), and pH (7), were monitored during the sampling process. The results indicate a relatively low incidence of Perkinsus infection, confirming Perkinsus compromises P. maxima health and aquaculture sustainability. Environmental factors such as temperature and salinity suggesting to influence the variation in infection prevalence. Ongoing surveillance is recommended to mitigate potential risks associated with protozoan parasitism.
