摘    要:目的]对粗唇鮠胚胎发育进行初步观察。方法]收集长江南京段的野生粗唇鮠作为亲鱼进行强化培育,通过人工授精进行人工繁殖,对粗唇鮠从受精开始至仔鱼出膜的整个胚胎发育过程进行观察。结果]粗唇鮠受精卵呈圆球形,吸水膨胀后,卵径约为2.2~2.4mm;在27~28℃水温条件下,粗唇鮠从受精至仔鱼出膜历时2496min,胚胎发育总积温约为1123~1165h·℃。结论]更好的了解了粗唇鮠胚胎发育的特点,并为鱼类资源保护利用等相关工作积累了基础生物学数据。

关 键 词:粗唇鮠  胚胎发育  积温

Abstract: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.
Keywords:Leiocassis crassilabris  Embryonic development  Accumulated temperature
