- Parásitos de peces nativos de la cuenca del Río Laja (Chile Central) y alcances sobre sus ciclos de vida V. L. OLMOS P. VICTORIANO C. VALDOVINOS E. HABIT Veterinaria parasites Percilia irwini Trichomycterus areolatus Diplomystes nahuelbutaensis The parasites from three species of native freshwater fishes, Trichomycterus areolatus, Diplomystesnahuelbutaensis and Percilia irwini, common from Central Chile were studied. These parasites are interesting because they could infect farmed salmon. Fishes were caught from an Andean watershed (37º20¿S; 72º56¿W) and examined in laboratory for parasites. A camera placed on a stereomicroscope and microscope were used for the photographs and observations. The specimens were later fixed in formalin at 5% or ethanol at 70%. The prevalence and intensity of seven parasites taxa were recorded: Mixobolus sp., Henneguya sp., Ancrynocephalidae (Monogenea), Zoogonidae (Digenea),Steganodermata sp (Zoogonidae), Nematoda and Pomphorhynchus sp. (Acanthocephala). P. irwiniharbours the most diverse and rich parasite assemblage with 4 species, followed by T. areolatus with 3taxa. D. nahuelbutaensis have only one parasite species but with high prevalence levels (89%). Thelife cycle of these parasites, the possible new host-parasite association and its consequences are discussed. 2003 artículo científico 0301-732X https://www.redalyc.org/articulo.oa?id=173013751007 es http://www.redalyc.org/revista.oa?id=1730 Archivos de Medicina Veterinaria application/pdf Universidad Austral de Chile Archivos de Medicina Veterinaria (Chile) Num.2 Vol.35
