Indonesia has very high fishery commodities production. It also has the potential to increase the economic condition of coastal communities. Grouper commodity contributes greatly in increasing the country's export. One obstacle that still affects the export is the quality of grouper commodities. Indonesian grouper often deals with parasitic infections. This study aimed to determine the type and prevalence of parasites that infect grouper commodities both cultivated, consumed and as ornamental fish in Buleleng Regency, Bali, Indonesia. Descriptive analysis was used in this research to clearly explain the prevalence of the infection. The results showed that 80 collected and examined grouper samples in fry, consumption, and ornamental commodities, nine samples were found to be positively infected. The type of parasite found was Trichodina sp. and Diplectanum sp. with a total prevalence of 11.25%. The target organs infected in tiger grouper (Epinephelus fuscoguttatus) commodities were gills and fins, showing the potential of quality reduction caused by parasite infection in grouper commodities. Prevention and curing action should be carried out to reduce further loss potential in the commodities of grouper in Buleleng, Bali.
