胡子鲶的胚胎发育

用无膜卵的培养方法,比较详细地观察了胡子鲶胚胎发育的过程,并从早期个体发育的本质着眼提出了卵裂、细胞分化和器官分化三个主要胚胎发育阶段。分析了胚胎发育与环境条件的适应性。根据胡子鲶胚胎发育的特点,初步讨论了苗种生产中应该注意的几个问题,同时提出胡子鲶可以作为鱼类细胞工程研究的一个比较理想的实验鱼材料。  

EMBRYONIC DEVELOPMENT OF CLARIAS FUSCUS (TELEOSTEI,SILURIFORMES)

The paper describes the embryonic development of the catfish, Clarias fuscus, through a culture procedure of chorion-free fertilized eggs. Based on the innate characters of the embryonic development, the author proposes three main developmental stages of this fish embryo: cleavage, cell differentiation, and organ differentiation, and analyses the adaptation of the embryonic development to the surroundings also. According to the distinguishing features of this embryo, the author discusses some problems relevant to artificial propagation of this fish and suggests that the embryo of Clarias fuscus is a rather ideal experimental object in the study of cell engineering.
