| new locality records for third-stage larvae of anisakis simplex (sensu lato) (nematoda: ascaridoidea) in euphausiids euphausia pacifica and thysanoessa raschii from prince william sound, alaska. | five euphausiid species (n=41,037) were collected in october 1997 from prince william sound, alaska, and examined for parasites. new locality records are claimed for third-stage larvae (l3) of whaleworm anisakis simplex (sensu lato) in two (0.019%) of 10,437 thysanoessa raschii, and in one (0.013%) of 7,443 euphausia pacifica. the l3 were about 19.5, 21.3 and 30.5 mm long. l3 were absent from 8,026 t. inermis, 10,302 t. longipes and 4,829 t. spinifera collected at the same time, and from 6,648 e ... | 2005 | 16175395 |
| 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 |
