| 中文摘要: |
| 2008年4月下旬至5月上旬,在金沙江攀枝花段共采集了160尾中华沙鳅(Botia superciliaris),对其繁殖生态学进行了初步研究。结果表明,中华沙鳅的绝对怀卵量最大为10681粒,平均为6780粒;相对怀卵量最大为443粒/g,平均为269粒/g。中华沙鳅性比接近1∶1,产漂流性卵,产卵类型为一次性产出,繁殖高峰期为5~6月。为保护我国鱼类的生物多样性,应加强对中华沙鳅繁殖种群的保护。 |
| 英文摘要: |
| 160 Botia supercilliaris had been collected in Jinsha River within Panzhihua from April to May，2008，and then a preliminary study on their reproductive biology was carried out. The results showed that the largest value of absolute fecundity and relative fecundity were 10 681 eggs/fish and 443 eggs/g body weight respectively; the average value of absolute fecundity and relative fecundity were 6 780 eggs/fish and 269 eggs/g body weight respectively. B. supercilliaris is a kind of fish with floating eggs and its style of spawning is one-off. The female-male ratio is nearly 1:1 .We believe that it is very important to protect the B. supercilliaris population.
