为了了解漠斑牙鲆受精卵的胚胎发育过程,为漠斑牙鲆育苗提供一定依据,对漠斑牙鲆的胚胎发育进行了初步观察。将受精卵培养在18℃～19℃、盐度33的海水中,利用显微镜对其胚胎发育过程进行连续观察,记录各个发育阶段的具体时间、状态并拍摄照片。受精卵经过卵裂、囊胚、原肠胚、神经胚、肌节胚、尾芽期、心跳期、出膜期等阶段的发育,经历60h30min成功破膜,进入胚后发育阶段。
In order to understand the embryonic development of Paralichthys olivaceus eggs and to provide a basis for nursery stock of Paralichthys olivaceus, the embryonic development of Paralichthys le Flusa was preliminarily observed. The fertilized eggs were cultured in seawater at 18 ° C ~ 19 ° C and salinity of 33, and their embryonic development was observed continuously with a microscope. The specific time and status of each stage of development were recorded and photographs were taken. The fertilized eggs through cleavage, blastocysts, gastrula, neuroblast, sarcomere, caudal bud, heartbeat, the stage of development and other phases of membrane, experiencing 60h30min successful rupture of the membrane into the embryonic development stage.
