摘要
本文研究了广东鲂人工繁殖的鱼苗在池塘育成亲鱼的方法。用LRH－A2与DOM混合催产效果最优。人工授精的关键是效应时间的掌握。本研究提出广东鲂最小性成熟年龄为2龄，届一年多次产卵鱼类，可进行一年2次性成熟产卵。胚胎发育程序与家鱼基本相似，胚胎发育最适水温范围约为24℃～28℃，临界水温上、下限分别为31℃和20℃。
The studies on the method of fry of artificial propagation of M. hoffmanni cultured into breeder in pond were carried out-Effect of LRH-A2+DOM for induced spawning is the best. Key of artificial propagation is the time control of response of biochemitary. 2 year-old fish reaches maturity. The fish breeds for two batches at least in a breeding season. The process of embryonic development is same essentially with cultivated fish. The optimun water temperature for emoryonic development ranges from 24℃-28℃and the critical water temperature is as the maximum (31℃) and the minimum (20℃).
