| 摘要: |
| 2008年5月20日，对海水网箱养殖的豹纹鳃棘鲈（Plectropomus leopardus Lacépède）亲鱼进行人工催产试验，并对获得的受精卵进行胚胎发育观察，描述其发育各期的形态特征及发育速度。豹纹鳃棘鲈的受精卵呈浮性，透明圆球形，卵径为816.5 μm±15.9 μm，具一直径约145.5 μm的大油球，有些受精卵还含有数个（1～6）小油球。在自然海区水温30.0～31.2℃条件下，胚胎发育时间为16 h32 min。 |

| Abstract: |
| On May 20, 2008, the Plectropomus leopardus Lac p de Broodstock, cultured in the marine cage at Li-an harbour of Lingshui county, was tested by artificially induced spawning and observed on embryonic development of the fertilized eggs. This thesis describes the morphological characteristic of the development phases and development rate: The zygote is float， transparent， spherical in shape, and 816.5 μm±15.9 μm in diameter with a big oil globule,but some ones also have small oil globule(1～6). At 30.0～31.2℃ and salinity 30 in natural sea water, the hatching time for 50% eggs after fertilization was about 16 h and 32 min. |
