Mature females were captured in the Mae Klong River, Thailand, from July to September 1998, and divided into five groups according to their ovarian development. Total lipid levels in the ovary increased with maturation, but no concomitant decrease in MG lipids was observed. Thus, the lipid requirements of the developing ovary are thought to be more dependent on the immediate ingestion of dietary lipid than on MG reserves. Higher proportions of neutral lipids (NL), mainly triacylglycerols (TG), were observed in both MG and ovary, whereas polar lipids (PL) predominated in muscle. In the ovary, total NL increased significantly along with maturation mainly due to an increase of TG and sterols.Phosphatidylcholine (PC) and phosphatidylethanolamine (PE) formed the bulk of ovarian PL and also increased significantly as maturation progressed. Major fatty acids in both MG and ovary were 14:0, 16:0, 18:0, 18:1<i>n</i>-9, 18:2<i>n</i>-6, 18:3<i>n</i>-3, 20:4<i>n</i>-6, 20:5<i>n</i>-3 and 22:6<i>n</i>-3. Significant increases in the levels of saturated and mono-unsaturated fatty acids were observed in both MG and ovary. The levels of <i>n</i>-3 highly unsaturated fatty acids (HUFA), particularly 20:5<i>n</i>-3, decreased in the MG as ovarian development proceeded. In contrast, an increase in the ovarian contents of <i>n</i>-3 HUFA was detected.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Variations in lipid classes and fatty acid content in tissues of wild <i>Macrobrachium rosenbergii</i> (de Man) females during maturation","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":"prawn; Macrobrachium rosenbergii; lipids; maturation","OtherDescriptors":"Lipids; Ovaries; Muscles; Polyunsaturated fatty acids; Biochemical composition; Prawn culture; Fatty acids; Sexual maturity; Natural populations; <i>Macrobrachium rosenbergii</i>; Thailand, Mae Klong R.","Notes":null,"AnaPub":2001,"MonPub":null,"DateUpdate":"2012-04-02","DateCreate":"2001-03-20","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000166576800010","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/S0044-8486(00)00497-X"},"refs":null,"anarec":{"AnaID":6923,"PubliDate":2001,"Pagination":"311-324","XtraPublOfAnaID":null,"ISBN":null,"Volume":"193","Issue":"3-4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42190,"SerRR":"Aquaculture.
