The organic enrichment is essential for maintaining continued fertility of <i>D. magna</i>.3. The organic enrichment can be replaced by the addition of pantothenic acid to vitamin B12 and thiamine without lowering the fertility of <i>D. magna</i>.4. The organic enrichment (or the vitamin mixture) does not act directly on <i>D. magna</i> but via the algae by changing their nutritional value for <i>Daphina</i>.5. Addition of vitamins to the medium in which the algal food is grown with crustacea may allow continuous cultures of herbivorous crustacea which are considered difficult to grow.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Dixenic culture of <i>Daphnia magna</i> Straus","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:31:37.458138","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1970,"MonPub":null,"DateUpdate":"2009-06-15","DateCreate":"2009-06-15","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1970I289600004","VABBcode":null,"OpenAcc":1,"DOI":"10.2307/1540367"},"refs":null,"anarec":{"AnaID":137561,"PubliDate":1970,"Pagination":"485-494","XtraPublOfAnaID":null,"ISBN":null,"Volume":"139","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42437,"SerRR":"The Biological Bulletin.
