| natural transfer of helminths of marine origin to freshwater fishes with observations on the development of diphyllobothrium alascense. | infective stages of helminths of 5 species that occur as adults in marine mammals were found in burbot, lota lota (l.) (gadidae), from the lower kuskokwim river (southwestern alaska): diphyllobothrium alascense rausch et williamson, 1958; pyramicocephalus phocarum (fabricius, 1780); corynosoma strumosum (rudolphi, 1801); corynosoma semerme (forsell, 1904); and pseudoterranova decipiens (krabbe, 1878). some larval stages were obtained also from smelt, osmerus mordax dentex steindachner, an anadro ... | 2000 | 10780552 |
| anisakids (nematoda: anisakidae) from stomachs of northern fur seals (callorhinus ursinus) on st. paul island, alaska: parasitological and pathological analysis. | anisakid nematodes parasitize the alimentary tracts of aquatic vertebrates, including northern fur seals (callorhinus ursinus) (nfs). the main purpose of this study was to estimate the prevalence, intensity, and species composition of anisakids in nfss on st. paul island, alaska, and to analyze changes in nfs infection with these nematodes during the last decades. the study was carried out on st. paul island, alaska, in july-august 2011-2013. stomachs of 443 humanely harvested nfs males were col ... | 2014 | 25216781 |
