摘  要:
The morphological characteristics of Betta splendens Regan in different embryonic development phases were observed and recorded in detail.The results showed the oosperm of Betta splendens Regan was round,opaque white and sinking,the average diameter of egg was 1.116 mm.When water temperature was 25.2~27.0℃,larvae were hatched out from oosperm in 36 h 54 min.According to the external morphological features in each growth period,seven stages of embryo development of Betta splendens were divided into,which were cleavage period,blastula period,gastrula period,neurula period,organogenesis period,heart-beating period and hatching period.
