西藏山溪鲵早期胚胎发育的初步观察

The Preliminary Observations on the Embryonic Development of Batrachuperus tibetanus

本文首次报段了有尾目山溪鲵属的西藏山溪鲵胚胎发育过程的观察结果.从受精到孵化约需68d.胚胎发育过程被初步划分为20个阶段.早期胚胎发育过程较之有尾目已报道的东方蝾螈、蓝尾蝾螈、中国小鲵为慢.

The obseyvations were made on embryonic development of Batrachu-perus tibetanus.The fertilized eggs developed normally and hatched in 68days in the water of 4-10℃.Based on their morphological characterisics,the developmental process of the embryos may be divided into 20 stages,which was slower than those of Cynops orientalis,Hynobius chinensis andCynops cyanurus churiongensis.
