本文采用人工干法授精获得斑鳜受精卵,在室内培养皿(静水)培育条件下对其各个发育阶段作了形态观察,井就胚胎的“延宕孵出”现象进行了初步探讨。
In this paper, artificial fertilization was used to obtain the fertilized eggs of the cantharidin. Morphological observation was made at various developmental stages under the condition of indoor petri dish (hydrostatic cultivation), and the phenomenon of “delayed hatching” of embryos was discussed.
