Abstract

This study reports the presence of Enterogyrus cichlidarum Paperna, 1963 (Monogenoidea: Ancyrocephalidae) in the stomach of Nile tilapia, Oreochromis niloticus Linnaeus, 1758, cultured in the State of Santa Catarina, Southern Brazil. A total of 98 fish originating from a fish pond culture in Joinville, South Brazil, were examined. The fish were collected in the winter of 2007, in the summer, autumn, winter and spring of 2008. After anesthetized and sacrificed in a benzocaine solution, their  stomachs were removed, bathed in 55°C water, fixed in 5% formalin for quantification and attainment of the prevalence rate, mean intensity, mean abundance and mounted in Hoyer's. Prevalence rate throughout the period was 94%. The greatest mean intensities occurred in August 2008 and November 2008, followed by July 2007, January and May 2008. The great majority of Monogenoidea are branchial and cutaneous ectoparasites, however reports of its invasion in the internal organs are rare. This study is the first report of Enterogyrus in Nile tilapia cultured in Brazil.
