The levels vary from 0-362 µg g<sup>-1</sup> <i>Artemia</i> (dry wt.). The aim of this study was to investigate the actual retinoid concentration in <i>Artemia</i> and compare it with levels in copepods. Samples of both DC-DHA Selco (INVE, Ghent, Belgium) from the bottle and after 12 h in the enrichment tank in addition to enriched and unenriched <i>Artemia</i> and copepods from a pond system were collected and analysed for vitamin A components. The analyses were conducted using two different HPLC (high pressure liquid chromatography) methods to ensure the justness of the results. The DC-DHA Selco contained 132.7 µg vitamin A g<sup>-1</sup>. After 12 h in the enrichment tank we could not detect any vitamin A. None of the following retinoids were observed in <i>Artemia</i> or copepods with any of the methods: all-trans-retinol (at-ROH), 9-cis-ROH or at-3,4-didehydro-ROH (at-3,4-dd-ROH). Method 2 detects several other retinoids when present, but none of the following were found in the two live prey organisms: cis or trans 3,4-dd-RA, cis or trans 3,4-dd-ROH, cis or trans 3,4-dd-RAL, cis or trans ROH or cis or trans RA. This implies that larvae feeding on either copepods or <i>Artemia</i> must meet their retinoid requirement from other sources than retinoids.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Quantitative and qualitative analysis of retinoids in <i>Artemia</i> and copepods by HPLC and diode array detection","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":"Artemia; copepods; dioarray; HPLC; retinal; retinoic acid; retinol;","OtherDescriptors":null,"Notes":null,"AnaPub":2005,"MonPub":null,"DateUpdate":"2015-11-06","DateCreate":"2011-12-22","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000229205700032","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.aquaculture.2005.01.017"},"refs":null,"anarec":{"AnaID":210613,"PubliDate":2005,"Pagination":"359-365","XtraPublOfAnaID":null,"ISBN":null,"Volume":"246","Issue":"1-4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42190,"SerRR":"Aquaculture.
