应用人工控制鱼类性别三系配套技术可以获得全雄莫桑比克罗非鱼。实验证明,这种人工获得的雄性鱼与天然莫桑比克罗非鱼的基因生理型和形态构造是一致的。因此,预测它们在生长等方面的经济性能也具有一致性。本实验初步报道这方面的研究结果。材料与方法实验所用的材料均为莫桑比克罗非鱼,但产生的途径不同。人工获得的雄鱼由雄性纯合系与原系配套((?)×(?)而来。简称实验雄鱼;天然雌、雄鱼指原系间配种((?)× Application of artificial control of fish, gender, three-line supporting technology can get all-male Mozambique tilapia. Experiments have shown that this artificial-derived male fish is consistent with the genetic physiology and morphological structure of natural Mozambique tilapia. Therefore, it is also predicted that they have the same economic performance in growth and other aspects. The experiment initially reported the results of this research. Materials and Methods Materials used in the experiments were all tilapia in Mozambique but differed in the way they were produced. Artificial males were derived from male homozygous lines with the original line ((?) × (?))
