San Francisco Bay <i>Artemia</i> with a good natural fatty acid profile and small body size could be offered earlier than the larger but HUFA-poor Great Salt Lake strain. The poor nutritional quality of the latter, however, could be corrected by enriching the nauplii with an omega3-HUFA emulsion for 24h, after which time high levels of the omega3-HUFAs 20:5 and 22:6 were obtained. When the <i>Artemia</i> diet offered before metamorphosis included natural or supplemented essential fatty acids, no significant differences in dry weight, length or survival of the fish were noticed, as compared to fish fed the naturally deficient GSL <i>Artemia</i> . Onset of metamorphosis and physiological condition after metamorphosis, however, were influenced by the HUFA content of the ingested prey. Seabass larvae fed SFB or enriched GSL <i>Artemia</i> started metamorphosis on day 19, while those in the non-enriched series never achieved metamorphosis and died of a nutritional deficiency syndrome by day 27. An indication of the physiological condition of the larvae and the early detection of the syndrome was possible by subjecting 21- and 25-day-old larvae to a stress test: abrupt exposure of the larvae to 65-ppt saline water resulted in abundant and early mortality in HUFA-deficient fish larvae. Fry receiving omega3-HUFA-fortified <i>Artemia</i> had a superior physiological condition which was reflected by significantly lower mortality figures in the stress test.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Improved larval survival at metamorphosis of Asian seabass (<i>Lates calcarifer</i>) using omega3-HUFA-enriched live food","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":1990,"MonPub":null,"DateUpdate":"2018-09-18","DateCreate":"2000-08-29","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1990EC38500007","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/0044-8486(90)90283-S"},"refs":null,"anarec":{"AnaID":3079,"PubliDate":1990,"Pagination":"63-74","XtraPublOfAnaID":null,"ISBN":null,"Volume":"90","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42190,"SerRR":"Aquaculture.
