ABSTRACT
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 percent) salmons and its prevalences of infection showed significant differences between female and male salmons. The 94,4 percent of total plerocercoids of diphyllobothrium were isolated from the stomach wall. Prevalence and mean intensity of infection by diphyllobothrium sp. did not show significant differences between fishes of different sex
