Abstract. Sufardin, Sriwulan, Anshary H. 2022. Gyrodactylus (Monogenea: Gyrodactylidae) on marine ornamental fish Amphiprion percula from a aquaculture facility in Indonesia. Biodiversitas 23: 1023-1030. As popular (MOF), clownfishes are widely traded globally due to their beautiful appearance and relative ease of maintenance the aquarium. There is large amount literature biology ecology, but still lacks data parasites, especially about monogenean gyrodactylidae. The first investigation was conducted during March-August 2019. study revealed occurrence infection clownfish A total 50 samples were collected farm located Takalar, South Sulawesi, Parasitological examination using smear method performed skin, fins, gills. Parasites each individual counted directly under stereomicroscope. Morphological measurements monogeneans ImageJ 1.46r software. Parasite infestation analyzed statistically Kruskal-Wallis test linear regression. Based morphology, parasites infecting A. identified as Genus resembled described black sea. prevalence spp. 100% caudal fin classified very severe with 1908 overall. This shows intensity range 8-75 parasites/fish categorized moderate intensity, which 6-55 parasite/fish for 55-100 infection. higher than other organs significantly positively correlated size. report Indonesia adds knowledge gyrodactylid host fishes patterns.
