Resumen

TORRES, Patricio et al. Infection by parasitic helmiths in Coho Sallmon, Oncorhynchus kisutch, during their return to Simpson River, Chile. Bol. chil. parasitol. [online]. 2000, vol.55, n.1-2, pp. 31-35. ISSN 0365-9402.  http://dx.doi.org/10.4067/S0365-94022000000100009.

Between may and july 1994, 17 adult returning salmons, Oncorhynchus kisutch, were collected in the River Simpson, Chile. All fishes showed infection by plerocercoids of Diphyllobothrium sp. in different locations: stomach, spleen, liver, mesenteries and gonads. Infection with larval cestodes of an unidentified species of Phillobothriidae was determined in the intestine of seven (41.2%) salmons and its prevalences of infection showed significant differences between female and male salmons. The 94.4% of total plerocercoids of Diphyllobothrium were isolated from the stomach wall. Prevalence and mean intensity of infection by Diphyllobothrium sp. did not show significant difference between fishes of different sex.
