| 摘 要： | Objective] The research aimed to provide technical basis for fry rearing of Silnrus asotus in Dongting Lake.Method] The induced spawning medicine was used in the experiment to conduct artificial induced spawning and fertilization for obtaining round green fertilized eggs.According to embryonic development,the morphological characteristics of embryo at different developmental stages were recorded detailedly through microscope.Result] The embryonic development of Silnrus asotus in Dongting Lake was divided into 7 stages,namely, blastoderm stage,cleavage stage, blastula stage, gastrula stage,neurula stage,organogenesis stage and pre-hatching stage.After hatched for 37 h 20 min in water at 22-24 ℃, fries were come out.Conclusion] The time sequence of Silnrus asotus in Dongting Lake was basically similar to that of other catfish,while its hatching time was shorter than that of other fish in Siluriformes.
