摘要
采用显微解剖、肉眼解剖、石蜡切片、光镜和扫描电镜观察等方法,系统观测全长5.5—260.0mm白鲫标本430余尾,描述了口径、鳃耙、侧突起、腭褶等摄食器官的形态学特点和数量性状在胚后发育过程中的变化规律;论述了白鲫的摄食方式和摄食机能,滤食器官发育与摄食方式和食物组成的转化,摄食器官发育与饲养生物学技术措施。为制定培育白鲫苗种和饲养食用鱼技术措施提供了理论依据。
Developmental morphology of feeding organ of crucian carp (Cara-ssius carassius cuvisri) varying from 5.5mm to 260.0mm in total length (n>430)was observed by gross anatomy, tissue sections,microscopy and scanning electronmicrocopy. Morphological and quatitative changes in mouth diameter, gill rakers,lateral protuberances and palatine folds were described during postembryonic de- velopment. The following aspects were discussed: (1) feeding mode and feedingfunction for crucian carp; (2) development of feeding organ and transition of fee-ding behavior; (3) relationship between changes in quantitative traits of feedingo gan and suitable size and composition of food; (4) development of feeding organand biological technique on culture of crucian carp.
