| 中文摘要: |
| 利用形态学和组织切片技术，研究了斜带石斑鱼(Epinephelus coioides)（♀）×鞍带石斑鱼(E. lanceolatus)（♂）杂交子代（青龙斑）仔、稚、幼鱼的消化系统发育，描述了其消化器官发育过程和组织学结构特征。研究表明，在水温为30±1℃的人工培育条件下，消化系统发育可划分为3个阶段：0日龄至3日龄为内源性营养阶段，初孵仔鱼卵黄囊很大，仔鱼生长完全靠卵黄囊，不具备摄食和消化能力。4日龄至5日龄为混合营养阶段，这个阶段青龙斑仔鱼消化功能不完善，开口饵料为小型轮虫，混合营养期是鱼类早期生长阶段的关键过渡期。6日龄之后仔鱼进入外源性营养阶段，卵黄囊已经完全被吸收，此后青龙斑仔鱼消化系统进一步发育，至25日龄时消化系统的结构和功能已经较为完善。通过研究青龙斑仔、稚、幼鱼的形态组织学特征，为其发育生物学研究和鱼苗健康培育提供理论依据，进一步充实青龙斑生物学研究文库。 |

| Using the morphological and histological technology to study the development of digestive system of Qinglong grouper(Epinephelus coioides ♀×E. lanceolatus ♂), and described its development processes of digestive organs and structure of organization. Studies showed that the digestive system development of Qinglong grouper could be divided into three stages: the endogenous vegetative stage (0－3 DAH), the larvae completely relied on the yolk sac, and didn’t have the feeding and digestion. The mixed vegetative stage (4－5 DAH), the mouth and anus opened, the digestive tract ran through. The exotrophic stage (after 6 DAH), the yolk sac had been completely absorbed. The structure and function of the digestive system of Qinglong grouper at 25 DAH developed gradually. In conclusion,development of the digestive system of Qinglong grouper were in accord with the growth,morphology development and perfection of functions during the early development. |
