摘要
对全长８．５－１９９ｍｍ的尼罗非鲫的横，纵，水平向石蜡连续切片进行了系统观察，描述了口腔壁，颌齿，鳃，耙，前咽顶壁和上下咽摄食器官胚后发育的组织结构特征。探讨了该结构特征与摄食方式和食性转化的关系，并对该结构的发育特点与青鱼，鲢的作比较。
Based on systematical observation of Nile Tiopa (Oreochromis niloticus ) 8. 5 ~199mm in length in cross-section, longitudinal-section and horizontal-section, this article discribes the histological characteristics of feeding organs including the wall of oral cavity, the jaw teeth, the gill raker, the top wall of anterior pharynx and the upper and lower pharyngeal teeth,etc. The relationship between the histological charactestics and the feeding mode and transition of food Composition were discussed. The histological charactersics of Nile hlapia feeding organs with that of othe important fresh-water culture fish were compared.
