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。 [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 stage Ⅰ and the testis was at stage Ⅱ at 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.
