Conteúdo: 	Representatives of the Chaetodontidae (Actinopterygii: Perciformes) are widely appreciated in the ornamental fish market, frequently suffering from overexploitation. Aquaculture offers an alternative to extractive fishing activities, promoting a conservation strategy that is more reliable than catch restrictions. Nevertheless, in order to develop culture protocols for a fish, it is first necessary to understand aspects associated with its biology. In this study, we aimed to gather information on the parasitic fauna of the butterflyfish Chaetodon striatus Linnaeus, 1758. From May 2014 to February 2015, specimens of C. striatus were collected using fish traps in the southeast coast of Brazil and transferred to a recirculating aquaculture system (RAS) where they were kept for further research. Fifteen specimens were anesthetized, biometrically measured and euthanized for parasitological analysis of their gills. Gills were fixed in 10% formalin, scraped and analyzed under stereomicroscope for detection of parasites. Parasitological indexes were calculated according to Bush et al (1997) and parasites were mounted in Hoyer?s medium on a slide for identification. Data is presented as mean ± standard deviation. Fish had total length of 12,7 ± 1,1 and weight of 60 ± 17,1. Prevalence of parasitism by Monogenea was 53%, mean intensity was 6 ± 1,8 and mean abundance was 2,7 ± 3,4. Monogenean parasites belonged to a single species, representative of the subclass Polyopisthocotylea and belonging to the Heteraxinidae family. This is the first report of this group of Monogenea in this fish species.
