摘要
连续观察了线纹尖塘鳢(Oxyeleotrislineolatus)自然产卵受精的胚胎和前期仔鱼各发育阶段的形态特征。在室温28～29℃下,线纹尖塘鳢的胚胎发育历时70h完成,仔鱼孵化出膜。胚胎发育可分为受精卵、卵裂期、囊胚期、原肠期、神经胚期、器官形成期、肌肉效应期和孵化出膜期8个连续的典型发育期。胚后发育以卵黄囊的消失为依据,划分为前期仔鱼。
The early life development stages of sleepy cod, Oxyeleotris lineolatus were observed and characterized. At indoor temperature of 28-29℃ , embryonic development of sleepy cod covered 70 hours and passed through eight phases： fertilized egg, cleavage stage, blastula stage, gastrulae stage, nerve embryonic stage, organ formation stage, muscle effect stage and pre-hatching stage. When the yolk sac disappeared, it was developed from the embryo to the pre-larva.
