Some of the herring may even have temporarily left the North Sea, and migrated, to the Faroe plateau. The anomalous distribution of the herring in 1988-1990 appears to be related to a short-term climatic variation. The years were characterized by high water temperatures during the preceding winter, and by a low abundance of <i>Calanus finmarchicus</i>, the principal food of the herring. The low abundance of <i>C. finmarchicus</i> was probably related to the high water temperatures. Both the high temperature and the scarcity of food could explain the northern distribution of the herring. Apart from the 1988-1990 anomaly, a long-term northward shift of catches occurred from 1960 to 1990. This northward trend in catches coincided with a gradual increase in winter temperature, and a sustained decrease of <i>C. finmarchicus</i>. The long-term shift in herring catches, therefore, could signify a gradual change in distribution of the stock, brought about by the same factors that caused the 1988-1990 anomaly. If the recent climatic trend towards higher winter temperatures continues, the anomalous distribution of herring in 1988-1990 could become the normal pattern in future years.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Northern distribution of North Sea herring as a response to high water temperature and/or low food abundance","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":"herring distribution, temperature, climatic variation, calanus\r\nC-HELGOLANDICUS, FINMARCHICUS, CALANUS, ENVIRONMENT, ATLANTIC","Notes":null,"AnaPub":2001,"MonPub":null,"DateUpdate":"2001-10-05","DateCreate":"2001-10-02","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":18946,"PubliDate":2001,"Pagination":"189-204","XtraPublOfAnaID":null,"ISBN":null,"Volume":"50","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45227,"SerRR":"Fisheries Research.
