Helgolandicus</i> (Claus) were determined. Samples were collected during May 1980 in the Celtic Sea. Individual Copepodite Stages 3, 4, 5, and Adult Male and Female Stage 6 were measured and analysed, and 36 linear regression equations derived for these variables together with mean values, standard deviations and 95% confidence limits. The range of nitrogen values in the fresh material, expressed as a percentage of dry weight, ranged from 8.08% plus or minus 0.80 (Copepodite Stage 3) to 10.89% plus or minus 0.27 (adult female); carbon values changed from 41.6% plus or minus 3.05 (mean plus or minus 95% confidence limits) for Copepodite Stage 3 to 50.97% plus or minus 2.63 in Copepodite Stage 5. The adult females had a high nitrogen and relatively low carbon content, while the converse was true for Stage 5 copepodites. There was aloss of dry weight from the frozen samples (57%) and the fixed samples (38%) compared with the mean of the fresh dry weight of all stages.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Effects of preservation on wet weight, dry weight, nitrogen and carbon contents of <i>Calanus helgolandicus</i> (Crustacea: Copepoda)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:11.625236","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1982,"MonPub":null,"DateUpdate":"2005-08-29","DateCreate":"2005-08-29","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1982PU61900007","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/BF00397044"},"refs":null,"anarec":{"AnaID":75923,"PubliDate":1982,"Pagination":"271-281","XtraPublOfAnaID":null,"ISBN":null,"Volume":"71","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43352,"SerRR":"Marine Biology: International Journal on Life in Oceans and Coastal Waters.
