摘要: 报道了2001~2003年对长江上游特有鱼类黑尾近红鲌开展人工繁殖试验的结果。黑尾近红鲌亲鱼来源于四川泸州长江上游一级支流龙溪河。催产剂为促黄体素释放激素类似物(LRHA),绒毛膜促性腺激素(HCG) 与鲤鱼脑垂体(PG)。采用一次注射法,并用干法进行人工授精。共进行了23次人工催产,催产成功的占16次,有效的占3次,失败的占4次;共注射雌鱼70尾,其中46尾雌鱼排卵,平均催产率65.71%,受精率8.33%~100.0%,孵化率0.50%~94.71%,获得仔鱼29.3万尾。对亲鱼选择、催产方法、孵化与苗种培育等技术细节进行了讨论。

Abstract: Artificial propagation of A. nigrocauda,an endemic fish to the upper reaches of the Yangtze River, was taken in 2001~2003. The parent fish came from the Longxi River, one of the firstorder tributary of the Yangtze River at Luzhou,Sichuan Province. LRHA, HCG, pituitary gland (PG), or their mixture were used for spawning inducing. The stripped eggs were fertilized using the dry method. Totally 70 females and 89 males were injected. All males released sperm and 46 injected females spawned. Fertilization rate ranged from 8.33% to 100.0%, whereas hatching rate were between 0.50% and 94.71%. Average latency was 11.8 hours during water temperature 20.5~28.0℃. The incubation lasted bout 38 hours from fertilization to hatching whereas the development took about 26 days from newly hatched larvae to juveniles covered with scales initially. Technical details on gravid fish selection, spawning inducement, and larvae breeding were summarized in this paper.
