摘　　要：2012年3月底至5月中旬,在青衣江、金沙江、岷江和大渡河对齐口裂腹鱼(Schizothorax prenanti)的野生生境、资源现状进行了现场调查。并在雅安采集青衣江水系驯养成熟齐口裂腹鱼亲本13尾,对其繁殖生物学进行了研究。结果表明,齐口裂腹鱼的绝对生殖力在16 031～35 217粒之间,平均为2.56万粒;相对生殖力为7.99±4.23粒·g-1。齐口裂腹鱼为一次性产卵型,繁殖高峰期为3～5月份。The spot investigations of wild habitat and current situation of natural resources of Schizothorax prenanti in Qiyijiang river, Jin-shajiang river, Minjiang river and Daduhe river were carried out from March to May of 2012. 13 matured domestication parent were collected at Ya＇ an city, and then their characteristics of reproductive biology were studied. The results showed that the value of absolute fecundity of Schizothorax prenanti was between 16 031 - 35 217 eggs/fish, and the average was 25 600 eggs/fish. The value of relative fecundity of body weight was 7.99 ±4.23 eggs/g. A kind of Schizothorax prenanti fish with its style of spawning was one-off and their crest-time of breeding was from March to May.
