【 摘 要 】

Cantang groupers (Epinephelus fuscoguttatus-lanceolatus) is a hybrid grouper species. This hybrid species has several advantages, one of the advantages is it has better resistance to disease. However, it does not guarantee that grouper fish can not be infected by parasite that leads to disease. This study aims to determine the prevalence and intensity of monogenean parasites that infest cantang groupers (Epinephelus fuscoguttatus-lanceolatus) from floating net-cages farm, at Mariculture Center Lombok, West Nusa Tenggara Indonesia. The study conducted on grouper with size ranging from 15 to 27.5 cm, body weight ranging from 55 to 233 g. The result showed that monogeneans was found in cantang groupers were Neobenedenia girellae (3.8-5.4 x 1.5-2.5 mm) that infested the fins, eyes, and fish skin and Pseudorhabdosynochus seabassi (0.52-0.68 x 0.12-0.25 mm) only found on gills lamella. The highest prevalence of monogeneans was found in mixed infestation of P. seabassi and N. girellae 50% in most of categories. The highest intensity of monogeneans was 10.09 individuals/fish in single infestation of Pseudorhabdosynochus seabassi.
