A total of 1,516 neon flying squid was collected over an extensive area (24°-47°N, 147°E-135°W) of the North Pacific Ocean from January to October during 1991-1995. These squid were examined for the occurrence of the following helminth parasites: ascarid third-stage larvae of<i> Lappetascaris</i> sp. Type A in the musculature of the mantle; tetraphyllidean metacestodes of<i> Phyllohothrium </i>sp. in the lumen of the caecum; and trypanohynch metacestodes of <i>Tentacularia</i> sp. on the inner surface of the mantle. The area of capsules formed by ascarid third-stage larvae of <i>Lappetascaris</i> sp. Type B on the stomach wall was also recorded as an indication of intensity of infection. As the North Pacific neon flying squid consists of two cohorts (i.e., winter-spring cohort and autumn cohort), levels of intensity of infection with each parasite in both cohorts were statistically compared between the western (west of 170°E), central (170°E-160°W), and eastern (east of 160°W) regions of the North Pacific Ocean (north of 35°N). Based on this analysis, the winter-spring cohort is separated into two stocks: the western North Pacific stock and the central-eastern North Pacific stock. The border of the distribution range of these stocks is 170°E. It is impossible to separate the latter stock into smaller regional groups, due to the small sample size trom the eastern region. The autumn cohort is divided into two stocks: the central North Pacific stock and the eastern North Pacific stock, which occur west and east of 160°W, respectively.","AbstractOtherLang":null,"BibLvlCode":"AM","StandardTitle":"Parasites as biological tags of stocks of neon flying squid <i>(Ommastrephes bartramii)</i> in the North Pacific Ocean","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1998,"MonPub":null,"DateUpdate":"2001-05-22","DateCreate":"2001-05-14","SecASFANote":null,"ConfID":null,"PeerRev":null,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":9006,"PubliDate":1998,"Pagination":"49-64","XtraPublOfAnaID":null,"ISBN":null,"Volume":null,"Issue":null,"BRefMon":8996,"BRefMonRR":"<b>Okutani, T.</b> (1998).
