| 中文摘要: |
| 用人绒毛膜促性腺激素（HCG）、促黄体素释放激素类似物（LRH—A2）、马来酸地欧酮（DOM）组合对尖头金线鲃（Sinocyclocheilus oxycephalus）催产获得成功，用鲤脑垂体5mg／kg和人绒毛膜促性腺激素1000IU／kg组合催产失败。采取2次注射（第1次注射LRH—A2 2μg／kg，第2次注射LRH—A2 8μg/kg＋DOM3mg／kg＋HCG 1000IU／kg）催产效果明显；采取遮光孵化，孵化率明显提高。 |
| 英文摘要: |
| Artificial reproduction of Sinocyclocheilus oxycephalus was tried in October and November, 2007. S. oxycephalus was collected from Heilongtan Reservoir in Shilin County, Yunnan Province, cultured in down-dam ponds simulating natural condition （600 m2 , water depth 1.0 m, with continuous water flow） and fed with commercial pellets containing 32% crude protein and 12% crude lipid. Matured individuals （males should be over 100 g/ ind. , 2 years old, and females, over 150 g/ind. , 3 years old） were selected and injected with hormone. Injection with 1 000 IU/kg HCG plus 5 mg/kg carp PG was failed to induce spawning, while injection with mixture of HCG, LRH-A2 and DOM induced spawning successfully. Double injections, first time with LRH-A2 2 μg/kg, second time with mixture of LRH -A2 8 μg/kg ＋ DOM 3 mg/kg ＋ HCG 1 000 IU/kg, had a good inducing result. During hatching, shading will improve hatching rate which is obviously higher than unshading one. |
