[Objective] This study aimed to observe the embryonic development process of Leiocassis crassilabris. [Method] Wild L. crassilabris collected from the Nanjing section of the Yangtze River was used as parent fish for intensive breeding and propagation by artificial insemination. The entire embryonic development process of L. crassilabris from insemination to hatching out of larvae fish was observed consecutively. [Result] Fertilized eggs of L. crassilabris are spherical, and the egg diameter is about 2.2-2.4 mm after water absorption; under conditions of water temperature ranging from 27 to 28 ℃, the embryonic development of L. crassilabris from insemination to hatching out of larvae fish lasted 2 496 min, with a total accumulated temperature of 1 123-1 165 h·℃. [Conclusion] This study is advantageous to better understand the characteristics of embryonic development of L. crassilabris and provides basic biological data for protection and utilization of fish resources and other related work.
