Different approaches have been investigated such as improved weaning strategies, the use of high quality early weaning diets, and the optimization of the <i>Artemia</i> consumption. All these approaches were verified at production scale in European sea bream and sea bass hatcheries. <i>Artemia</i> consumption was reduced by appropriate weaning strategies based on revised feeding regimes. Using Inve's existing high-quality weaning diets, <i>Artemia</i> consumptions for the production of European sea bass and sea bream were decreased from 150kg to 90kg and from 120kg to 70kg cysts per million fry produced, respectively. New high-quality early weaning diets, developed through modem feed processing technology including live food substitution components, could further reduce the <i>Artemia</i> consumption by another 30-40% without impairing larval survival and quality .A more efficient use of <i>Artemia</i> was achieved by the introduction of a prolonged <i>Artemia</i> enrichment technique that allowed a 25- 30% nauplius biomass increase. Adapting the feeding regime in terms of this biomass increase provided a further decrease in <i>Artemia</i> cysts consumption. Besides the economical benefit, an improved quality was observed for the fry fed with prolonged enriched <i>Artemia metanauplii</i>. Above-mentioned strategies showed that the <i>Artemia</i> consumption for sea bass and sea bream could be reduced considerably, although the lower limit to which the <i>Artemia</i> consumption can be decreased has not been determined until now. The effect of a drastic <i>Artemia</i> reduction without compromising larval survival and quality in terms of deformity levels still needs to be investigated.","AbstractOtherLang":null,"BibLvlCode":"AMS","StandardTitle":"Progress at production scale with various <i>Artemia</i> substitutes and supplements for marine fish larvae","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":2001,"MonPub":null,"DateUpdate":"2004-08-02","DateCreate":"2004-08-02","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":64648,"PubliDate":2001,"Pagination":"157-161","XtraPublOfAnaID":null,"ISBN":null,"Volume":"30","Issue":null,"BRefMon":58190,"BRefMonRR":"<b>Hendry, C.I. <i>et al.</i></b> (2001).
