Genus Rhabdochona Railliet, 1916

Rhabdochona denudata (Dujardin, 1845) Ralliet, 1916

For the first time in Latvia, this freshwater water nematode has been reported in the intestine of four fish species by S. S. Shulman (1949) as syn. Ichthyospirura filliformis (Zschokke 1884) . In total, this nematode was found in seven fish species: Abramis brama , Alburnoides bipunctatus , Alburnus alburnus , Leucaspius delineates , Leuciscus cephalus , Rutilus rutilus , Sander lucioperca . The highest intensity of invasion was in breams, where 20.8% of bream in Sivers Lake was infected

( Kirjusina & Vismanis 2004). In the life cycle, mayflies Habroleptoides modesta (Hagen) and Habrophlebia lauta (Eaton) or larvae of Hydropsyche ( Trichoptera ) are intermediate hosts ( Vojtkova 1971, Moravec 2007). R. denudata infects many species of cyprinids, mainly members of the subfamily Leuciscinae (Moravec 1994) . Predators such as Sander lucioperca are accidental infections mostly through feeding on the definitive hosts.
