In a first experiment, shrimp (zoea 2-postlarvae 11) were fed rotifers (<i>Brachionus plicatilis</i>) and <i>Artemia</i> spp. nauplii that were enriched with different self-emulsifying concentrates: one HUFA-free coconut oil (T1), and three iso-HUFA concentrates with DHA/EPA ratios of 0.6 (T2), 2 (T3) and 4 (T4), respectively. In a second experiment, postlarvae were fed for 25 days (starting from postlarvae 10) on isolipidic semi-purified diets: one HUFA-free control (TA), and four iso-HUFA diets with DHA/EPA ratios of 0.6 (TB), 0.9 (TC), 1.8 (TD) and 3.64 (TE), respectively. Experiment 1 revealed no significant differences in production characteristics, except that resistance to a counter-current stress in postlarvae 11 was significantly lower in T1 than in T2 and T3 (p<0.05). In experiment 2, postlarvae of TA had a significantly lower dry weight than the other treatments at the end of the trial. The effect of the DHA/EPA ratio within the experimental limits could not be demonstrated. Analysis of the fatty acid composition of the shrimp showed notable changes of n-3 HUFA concentrations during the metamorphosis from mysis to postlarvae, and a different response to the dietary concentrations of DHA compared to EPA.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The effect of dietary n-3 HUFA and 22:6n-3/20:5n-3 ratio on white shrimp larvae and postlarvae","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":1997,"MonPub":null,"DateUpdate":"2001-11-28","DateCreate":"2000-08-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1997WU24600003","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":2987,"PubliDate":1997,"Pagination":"113-126","XtraPublOfAnaID":null,"ISBN":null,"Volume":"5","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44242,"SerRR":"Aquaculture International.
