The use of these tilapia has, in the past, been confined predominantly to the production of monosex fry for commercial culture, and indeed a potential new method for the commercial production of 100% YY male <i>O. niloticus</i> is discussed. However, these tilapia have other uses, some of which are illustrated. In <i>O. niloticus</i> the use of hormonal sex-reversal and gynogenesis has enabled the production of tilapia which produce 100% male offspring (the \"YY\" male tilapia: produced by gynogenesis on the eggs of a phenotypically female, sex-reversed <i>O. niloticus</i>), and the production of tilapia which produce 100% female offspring (phenotypically male sex-reversed tilapia: produced by oral dosage of 17 alpha-methyltestosterone). These monosex-producing fish have been used in three ways: 1) in morphometric investigations; 2) in the study of the effects of sex-influencing hormones; and 3)in the analysis of the sex-determining mechanisms in tilapia. Further potential uses of these, and similar fish, are discussed.","AbstractOtherLang":null,"BibLvlCode":"AM","StandardTitle":"The uses of unusual tilapia in the laboratory (Abstract)","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":1989,"MonPub":null,"DateUpdate":"2001-08-17","DateCreate":"2001-08-07","SecASFANote":null,"ConfID":null,"PeerRev":null,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":14971,"PubliDate":1989,"Pagination":"573","XtraPublOfAnaID":null,"ISBN":"90-71625-03-6","Volume":"1","Issue":null,"BRefMon":14854,"BRefMonRR":"<b>De Pauw, N. <i>et al.</i></b> (1989).
