摘  要：
对人工繁殖的异齿裂腹鱼Schizathorax oconnori胚胎发育和仔鱼的早期发育进行观察,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。异齿裂腹鱼的成熟卵近似于圆球形,呈淡黄色,卵径为(2.92±0.16)mm;受精后35 min卵膜吸水膨胀,卵膜径达(3.72±0.31)mm。在13.0～14.5℃条件下,孵化时间为193.22 h。异齿裂腹鱼胚胎发育速度存在明显的个体差异,孵化期历时92.83 h。初孵仔鱼全长为(8.97±0.31)mm。10日龄仔鱼初次摄食,进入混合营养期。

摘  要：
The fertilized eggs were collected in Schizothorax oconnori by hormone injection and dry-fertilization, and were hatched at temperature 13.0-14.5℃.The embryonic and larval development of Schizathorax oconnori were observed consecutively,during which the morphological feature and development characteristics were described. The adhesive egg were found to be about glutinous,light yellow in color,and(2.92±0.16)mm in diameter, (3.72±0.31)mm 35 min after fertilization and inflation.The larvae were hatched 193.22 h after fertilization at water temperature of 13.0-14.5℃,and the newly hatched larvae had mean total length of(8.97±0.31)mm, and initial feeding in 10 days.There was distinct difference in the embryonic development rate,with an incubation period of 92.83 h.
