| Abstract: | In this article, taking Auborne tilapia pure lines, which were introduced from American by Freshwater Fishery Research Centre, as parents for hybrids production, the means of mass selection was used in order to preserve the excellent parental traits and in-crease the male proportion. The male proportion was more than 95% through the crossbreeding between O.nilotica♀and O.aurea ♂over 6 years, 0.75 million of replacement parents had been cultured, 0.52 billion of hybridized tilapia fingerlings were produced. |
