Marcia Cristina Nascimento Justo, Anna Kohn

Resumo


Several fish species are known as host for Digenea trematods. Here, we describe three trematod species as parasites of the Bigeye tuna (Thunnus obesus), which  is an important fishing resource for Brazil. We examined 35 specimens of T. obesus obtained from fishermen in Cabo Frio, Rio de Janeiro, southeastern Brazil. We found Brachyphallus parvus and Tetrochetus coryphaenaein the stomach and Lecithochirium microstomumin the intestine of fish.

Keywords: Brachyphallus parvus. Fish parasites. Lecithochirium microstomum. Tetrochetus coryphaenae.
