黄颡鱼已成为我国重要的淡水养殖品种之一。单性别雄性黄颡鱼在相同条件下，雄性的生长速度普遍快于同胞雌性，在水产养殖中具有重要的应用价值。本研究通过性逆转、雌核发育、子代测定等方法筛选出YY超雄和YY生理雌黄颡鱼，为实现YY超雄和XY全雄黄颡鱼的规模化生产奠定基础。2008年至2010年共生产YY超雄约12.3万尾，随机抽样生产XY全雄鱼苗约8100万尾，雄虫率100%。因此，这些结果表明，YY超雄性和YY生理雌性黄颡鱼可以存活和繁殖。YY超雄黄颡鱼单性繁殖技术稳定可靠，在黄颡鱼养殖中具有很大的应用潜力。
Yellow catfish has become one of the most important freshwater aquaculture species in China. The mono-sex male yellow catfish has important application value in aquaculture because the male grows generally faster than the sibling females under the same conditions. This study has screened YY super-male and YY physiological female yellow catfish by sex reversal, gynogenesis, and progeny testing, which can help to achieve the large-scale production of YY super-male and XY all-male. From 2008 to 2010, about 123,000 YY super-male were produced, and about 81 million XY all-male fry were produced with 100% male rate by random sampling. Therefore, these results indicate that YY super-male and YY physiological female yellow catfish can be viable and fertile. We conclude that the mono-sex breeding technique by YY super-male yellow catfish is stable and reliable, which has great potential for application in yellow catfish aquaculture.
