摘要
对沙塘鳢(Odontobutis obscura)胚胎和仔鱼的发育进行了观察,描述了各发育阶段的形态特征。在22℃恒定条件下,沙塘鳢的胚胎发育历时528h,可分为28个发育分期。在整个发育过程中,各个器官如眼、耳囊、心脏、肾脏、肝脏、消化道、鳔、胸鳍和尾鳍等得到优先发育。
At 22℃ ,the embryos Odontbutis obscura hatched by 528 h,and the embryo development could be divided into 28 stages o The eye sac, ear vesicle, heart, digestive tract, kidney, swimbladder, pectoeal and tail fin were developed preferentially
