| 摘 要： | 目的]为缺帘鱼人工繁殖提供试验依据。方法]通过组织切片技术，研究水泥池养殖缺帘鱼的生物学特征和性腺发育情况。结果]结果表明：3龄缺帘鱼卵巢发育到I期，精巢为Ⅱ期；4龄缺帘鱼雄鱼可以发育至性成熟；4-5龄可以进行人工催产。缺帘鱼精巢为叶型壶腹型结构。结论]雌雄鱼性腺发育存在不同步现象，需进一步研究并调节其生长生态环境。

| Abstract: | Objective]The research aimed to provide experimental references for the artificial propagation of Brycon cephalus.Method]Gonadal development of B.cephalus cultured in cement pool was histologically investigated on biology characters and gonadal development.Result]The results showed that the testis in B.cephalus was of lobular ampulla type.The ovary was at stageⅠand the testis was at stage Ⅱat the age of 3.The fishes were matured at the age of 4,induced spawning could be carried out at 4-5 years old.Conclusion]Asynchrony of ovary and testis needed to be adjusted by regulating ecological conditions. |
