"Helminths were observed in all 68 flying squid, Ommastrephes bartrami (females with mean mantle length of 38.7 ± 3.6 cm and total mean wet weight of 2.1 ± 0.7 kg), examined from five drift gillnet sets off the west coast of North America in the summer of 1987 between 41°03' and 48°23' N latitude and 129°49' and 133°08' W longitude. All flying squid were infected with 10 to 166 juvenile Hysterothylacium sp. (Nematoda) that were mainly of small size (about 6 mm in length) and located within capsules on the stomach wall (average of 3.3 ± 1.4 specimens per capsule). Approximately 2% of all Hysterothvlacium sp. ranged from about 20 mm to 35 mm in length and were encapsulated in the mantle or free on the surface of the gills. Eleven Anisakis simplex larvae were encapsulated on the visceral tissues of nine of the flying squid. Metacestodes of Phyllobothrium sp. were recovered from 94.1% of the squid (1 - 121 specimens per squid) and one metacestode of Tentacularia sp. (probably T. coryphaenae) was found in the sample bag that held one flying squid. The only adult helminths recovered were seven Rhadinorhynchus sp. (Acanthocephala) from the stomach and pyloric caecum of three squid. The parasite fauna of these squid was different from that previously reported for O. bartrami from other oceans occupied by this circumpolar species and was different from records from other species of the family Ommastrephidae from the Pacific Ocean"--Abstract, page iii.
