中文摘要：

2012年5-8月及2013年5-8月,在稻田网箱中设置不同的生态因子,研究了不同密度、雌雄配比、水位、泥土深度、光照时间和栖息物对黄鳝Monopterus albus产卵的影响。试验表明：安徽地区黄鳝产卵大约在6-8月,历时约80 d,并在6月下旬和8月上旬出现两次产卵高峰;网箱条件下,随着密度的增加,产卵数增加,当密度大于6尾/m2时,产卵率下降,从性比结构来看,随着性比结构中雌鳝比例的增加产卵数呈现增加的趋势。水位、泥土深度和光照时间均显著影响黄鳝产卵率（P〈0.05）,栖息物对产卵率无显著影响（P〉0.05）;在泥土深度一定的情况下,随着水位加深产卵率逐渐降低;在水位一定的情况下,随着泥土深度的增加,产卵率逐渐升高,且水位和泥土深度对黄鳝产卵率有着明显的交互作用;随着光照时间增加,产卵率逐渐升高,不遮光组的产卵率最高。

英文摘要：

This paper studied the effects of density, sex ratio, water level, depth of soil, illumination time and habitat on the spawning rate of Monopterus albus in net cages from May to August in 2012 and 2013. The results showed that, the spawning period of Monopterus albus lasted for 80 d （ from June to August in Anhui） with two spawning peaks in late June and early August. The number of spawning increased along with density in cages which will be declined when the density is greater than 6 tail/m2. Additionally, the increase number of female eel will increase the spawning number. Significant dif- ferent spawning rates （ P 〈 0.05 ） were observed among water level, soil depth and illumination time. Habitat had no significant influence on spawning rate （ P 〉 0.05 ）. In certain soil depth, spawning rate generally decreased with increasing water level. For water level, spawning rate increased with the increasing soil depth. Furthermore, interaction between water level and soil depth had significant impact on spawning rate; and spawning rate generally increased with increasing illumination time, and the highest rate was observed in the all-day light spawning group.
