| Abstract: | Objective] This study aimed to observe the embryonic development of the F1 hybrid between Ryukin(♀) and Dragon-eye(♂).Method] Embryonic development of the F1 hybrid and parents between Ryukin(♀) and Dragon-eye(♂) was observed with XTL-2400 anatomical lens continuously.The organ characteristics and structures at each development stage were observed with OLYMPUS CKX41 microscopes,and photographed and recorded with a digital camera.Result] At a water temperature of 25 ℃,the hatching time of the F1 hybrid is 51.3 h,the hatching time of Ryukin embryo is 52.4 h and that of Dragon-eye embryo is 56.3 h.Conclusion] This study provides certain theoretical and practical basis for improving morphological characteristics of the existing Dragon-eye goldfish. |
