摘  要：
对人工干法授精的光唇裂腹鱼(Schizothorax lissolabiatus)胚胎发育和仔鱼早期发育进行观察,描述了从受精卵到卵黄囊期仔鱼发育时期的时序和形态特征。光唇裂腹鱼的成熟卵近似于圆球形,呈金黄色,卵径为(2.2±0.13)mm;受精后12 min卵膜吸水膨胀,卵径达(3.2±0.21)mm。在水温15~17℃的条件下,平均孵化时间为174.28 h。初孵仔鱼全长为8.5 mm,6日龄仔鱼初次摄食丰年虫,进入混合营养期。

摘  要：
The aim of the study was to observe the embryonic and early larval development of Schizothorax lissolabiatus which was incubated from the oosperm obtained by artificial fertilization without water.The time sequence and morphological characteristics of this fish were presented from the fertilized egg to the yolk sac and early larvae during the cultivation period.The mature egg of this fish was close to sphericity and had golden color,with a diameter of(2.2±0.13) mm.The egg membrane began to absorb water and expand in 12 min after fertilization,the diameter of the oosperm was(3.2±0.21) mm.The average incubation period was 174.28 hrs at the water temperature of 15 ~ 17℃.The length of the early larval fish was 8.5 mm and the 6-day-old larva would firstly feed on the fairy shrimp and then entered the mixed nutritional stage.
