| 中文摘要: |
| 采用组织学方法研究了中华鲟眼球早期发育过程。结果表明,孵出24h仔鱼晶状体开始分层,睫状肌到达晶状体;3日龄仔鱼虹膜分化完毕,出现视神经;25日龄视网膜内视觉细胞发育完善;60日龄眼球各组织发育完善,视神经粗大成束。中华鲟眼睛较小且晶状体调节能力较差,因此,可推断中华鲟仔鱼的视觉在觅食作用中不起重要作用。 |
| 英文摘要: |
| Histological studies on eyeball of the Chinese sturgeon, Acipenser sinensis showed that crystalline lens was laminated and musculi ciliaris was developed to crystalline lens. Iris was developed and optic nerve happened at 3 dph （days-post-hatch）. At 25 dph, visual cells of retina were developed. While eyeball tissues were developed at 60 dph and optic tract was thickened. The eye is small and accommodation of the Dens is weak. Therefore, it is may conclude that sense organ of vision of young Chinese sturgeon played an unimportant role in feeding behavior. |
