The test was used in a study of quantitative (n-3) highly unsaturated fatty acids (HUFA) requirements in larval <i>Lates calcarifer</i> and <i>Siganus guttatus</i>. It enabled to suggest fast intervention at reduced larval quality and allowed to prevent mass mortalities. The stress test offered valuable information for the quantification study of fatty acid requirements in marine fish larvae. In <i>Lates</i> demands for fatty acids were detected in metamorphosis. In <i>Siganus</i> on the other hand, the sensitivity of the larvae was considerably reduced after short (n-3) HUFA boosting of the larval food, however, prolonged HUFA-administration didn't enhance larval quality nor metamorphosis. For siganid larvae, and possibly also for older seabass fry, too high (n-3) fatty acids level might have a negative effect on the growth of the animals.Considering the information obtained with this testing procedure the use of a stress test should be encouraged as a handy tool in testing nutritional requirements of aquaculture species at various stages of their development, or under different zootechnical conditions.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A simple test for quality evaluation of cultured fry of marine fish","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:01.897972","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1992,"MonPub":null,"DateUpdate":"2013-06-10","DateCreate":"2000-08-24","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":2761,"PubliDate":1992,"Pagination":"2135-2142","XtraPublOfAnaID":null,"ISBN":null,"Volume":"57","Issue":"4b","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45392,"SerRR":"Mededelingen van de Faculteit Landbouwwetenschappen.
