The observed seasonal and long-term changes in abundance, biomass and production are discussed in relation to hydrographical differences. Long-term annual mean numbers per m² are about 500 in Kiel Bay and 450 in the German Bight. Mean biomass (ash-free dry weight) is 0.64 g. m<sup>-2</sup> in Kiel Bay compared to 0.71 g. m<sup>-2</sup> in the German Bight, the corresponding production values being 1.7 and 2.3 g .m<sup>-2</sup> .a<sup>-1</sup> due to the better growth in the German Bight. Annual P/B ratios are 2.7 and 3.2 respectively. The production estimates suggest the importance of <i>Diastylis</i> in the demersal food web. Both populations are mainly controlled by physical factors, in particular by low winter temperatures.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Seasonal and long-term population fluctuations of <i>Diastylis rathkei</i> (Crustacea: Cumacea) of Kiel Bay and German Bight","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":1982,"MonPub":null,"DateUpdate":"2019-07-04","DateCreate":"2001-07-31","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":14353,"PubliDate":1982,"Pagination":"141-150","XtraPublOfAnaID":null,"ISBN":null,"Volume":"16","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44573,"SerRR":"Netherlands Journal of Sea Research.
