摘  要：
显微观察并拍摄鲈鲤[Percocypris pingi pingi(Tchang)]胚胎发育及胚后发育过程的形态特征,描述了鲈鲤早期发育过程。结果显示:成熟鲈鲤卵呈球形、桔黄色,为粘性卵,卵径2.2 mm,卵膜遇水膨胀后,最大外膜径达3.2~3.8 mm。受精卵在水温(18±0.5)℃条件下,受精2 h 28 min后开始第1次卵裂,受精后45 h 23 min开始形成器官,受精后126 h 28 min孵出仔鱼。初孵仔鱼全长为10.4 mm,卵黄囊大而侧扁。根据胚胎发育过程的形态特征,可将鲈鲤胚胎发育过程分为受精卵、卵裂、囊胚、原肠胚、神经胚、器官发生和出膜7个连续阶段,32个时期。在水温18.8~25.0℃下,鲈鲤从出膜仔鱼至幼鱼历时93 d。根据其胚后发育的形态、生态特征可分为3个阶段:卵黄囊期仔鱼、晚期仔鱼、稚鱼。

摘  要：
The embryonic and early stage larval development of Percocypris pingi pingi( Tchang) were studied. The results showed that the fully mature eggs were spherical,aurantium,sticky,2. 2 mm in diameter,and 3. 2- 3. 8 mm after absobing water. When water temperature was( 18 ± 0. 5) ℃,126 hours and 28 minutes was needed to hatch the embryos,which were described as follows: fertilized egg at 0 minute,2-cell stage at 2 hours and 28 minutes after fertilization,after fertilization 45 hours and 23 minutes organs begin to form,and larvae at 126hours and 28 minutes after fertilization. Newly hatched larvae had a total length of 10. 4 mm and yolksac was big and compressed. The embryonic development process could be divided into 7 stages,including fertilized egg stage,cell division stage,blastula stage,gastrula stage,neurula stage,organ formation stage and hatching stage. They contained thirty-two developing phases,whose characteristics were described in detail. According to morphological characters and ecological character of postembryonic development of Percocypris pingi pingi( Tchang),three phases were devidied as yolk-sac stage,late-larvae stage,junenile stage from larvae to juvenile at 18. 8- 25. 0 ℃ of water temperature.
