| 摘 要： | 使用LHRH—A2＋DOM＋PG混合催产剂对从海南引进经池塘驯化养殖5冬龄的海南长臀鲍进行催产，并用日产80i光学显微镜观察胚胎发育过程。取得平均催产率88．9％，平均受精率82．3％，平均孵化率68．7％的效果。成熟的卵子为圆球形、淡黄色、粘性卵。在水温24．8～27．0℃条件下，其受精卵经细胞期、囊胚期、原肠期、体节出现期、器官出现期和出膜前期等多个发育时期孵化出膜，所需时间为82h 15min。拍摄了胚胎发育照片25幅。

| Abstract: | In this study,Cranoglanis bouderius multiradiatus was introduced from Hainan and domesticated about five years in pond.The mixture of LHRH-A2+DOM+PG was injected into Cranoglanis bouderius multiradiatus before their embryonic development was observed by Nikon 80i optical microscope.These results were concluded.The average of spawning rate(induction rate) was 88.9%,and the average fertilization rate and hatchability(hatching rates) were 82.3% and 68.7%,respectively.Their mature eggs were spheroidal,light,yel... |
