Because cultured rotifers are relatively poor in eicosapentaenoic acid (EPA: 20:5n-3) and docosahexaenoic acid (DHA: 22:6n-3), it is essential and therefore common practice to enrich these live prey with emulsions of marine oils. The short-term exposure to oil emulsions results in lipid-encapsulated rotifers with high EPA and DHA levels. However, these rotifers are prone to fast losses of their gut content and show a distortion in their protein/lipid balance. Rather than submerging rotifers in oil emulsions, it is often preferred to use formulated culture diets when medium to low enrichment values are needed in live prey. The use of these diets contributes not only to the filling of the gut of the rotifers with nutrients, it generally creates a more stable entire body composition which is important especially when rotifers are not consumed immediately by the larvae. New culture techniques for rotifers, such as closed recirculation systems, are offering new possibilities for continuous supplies of high quality rotifers at 10 times higher densities than in batch cultures. The production increase in these systems is explained by the better water quality obtained by the introduction of protein skimmers. ozone treatment, and biological filtration. Although disinfection of rotifers remains a bottleneck, it has been observed that rotifer populations cultured at high densities are not prone to higher bacterial infestation. Also, the problem of unexplained mortalities in batch cultures seems to be partly solved by the introduction of recirculation systems or by bacterial management (introduction of probionts). which allow more reliable rotifer production.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Advancement of rotifer culture and manipulation techniques in Europe","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"rotifer production; live feeds; HUFA; DHA; EPA","OtherDescriptors":"Marine fish; Fish larvae; Diets; Rearing; Fatty acids; Biofilters; Water quality; Recirculating systems; Ozone; Animal nutrition; Nutritive value; Food organisms; Bacteria; Pisces; Rotifera; Europe","Notes":null,"AnaPub":2001,"MonPub":null,"DateUpdate":"2013-01-11","DateCreate":"2001-09-25","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000170587300007","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/S0044-8486(01)00697-4"},"refs":null,"anarec":{"AnaID":18299,"PubliDate":2001,"Pagination":"129-146","XtraPublOfAnaID":null,"ISBN":null,"Volume":"200","Issue":"1-2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42190,"SerRR":"Aquaculture.
