通过观察在全人工繁育条件下大鲵的胚胎发育及器官的形成过程,对比仿天然生态养殖的大鲵胚胎发育过程,对大鲵从受精卵到孵化为幼苗出膜进行了连续系统的形态学观察。结果发现:人工繁育的大鲵在胚胎发育至神经胚期和器官形成期,有明显的“神经沟出现”、“视泡形成”和“心脏跳动”的特征,因而在传统分期的基础上增加了“神经沟期”、“视泡形成期”和“心脏跳动期”,从而将大鲵的胚胎发育过程细化为23个时期;虽然同种大鲵的人工繁育和仿生态养殖方式绝大部分发育时期的外形特征基本相同,但在卵裂期和神经胚期依旧存在差异;并利用人工繁育技术,提高其孵化率,为进一步研究大鲵的人工繁育提供理论基础和实验材料。
通過觀察在全人工繁育條件下大鯢的胚胎髮育及器官的形成過程,對比倣天然生態養殖的大鯢胚胎髮育過程,對大鯢從受精卵到孵化為幼苗齣膜進行瞭連續繫統的形態學觀察。結果髮現:人工繁育的大鯢在胚胎髮育至神經胚期和器官形成期,有明顯的“神經溝齣現”、“視泡形成”和“心髒跳動”的特徵,因而在傳統分期的基礎上增加瞭“神經溝期”、“視泡形成期”和“心髒跳動期”,從而將大鯢的胚胎髮育過程細化為23箇時期;雖然同種大鯢的人工繁育和倣生態養殖方式絕大部分髮育時期的外形特徵基本相同,但在卵裂期和神經胚期依舊存在差異;併利用人工繁育技術,提高其孵化率,為進一步研究大鯢的人工繁育提供理論基礎和實驗材料。

This study through the observation under the condition of total artificial breeding of giant salamander embryo development and the formation process of organs, the contrast of copy is natural the salamander embryo developmental process of ecological breeding, the salamander from fertilized egg to hatch for seedlings out membrane on the morphology observation of continuous system. Results: artificial breeding of the strain to its embryonic stage in embryonic development and organ formation, there are obvious "nerve ditch", "optic vesicle formation"and"heart beat"characteristics, and on the basis of the traditional stage increased"neural groove period","optic vesicle formation"and"heart beat"period, and the appearance of embryonic development process is divided into 23 times;Although the same strain of artificial breeding and imitated ecological breeding way most basic same, appearance features of development but in cleavage stage and neural embryo stage still exist differences; And by using artificial breeding technology, improve its hatching rate, hatching rate. Providing theoretical basis for further study on the artificial breeding of giant salamander and experimental materials.
