中文摘要:
      采用显微解剖、石蜡切片、光镜和扫描电镜观察等方法,系统观测全长6.0-223.0mm尼罗罗非鱼标本278尾,描述了口径、鳃耙、口腔上腭、颌齿、咽齿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;论述了尼罗罗非鱼的摄食方式和摄食机能,摄食器官发育与摄食方式的转化,摄食器官数量性状发育与适口食物规格和食物组成的转变,摄食器官发育与饲养生物学技术措施.为制定培育尼罗罗非鱼苗种和饲养食用鱼生物学技术措施提供了可靠依据.
英文摘要:
      Morphological development of feeding organ of Oreochromis niloticusvarying from 6. 0 mm to 223. 0 mm in total length (n271) was observed throughdissection, sectioning, light and scanning electron microscopy. The followingsubjects were described:1. Development characteristics of gill rakers, buccal palatine, jaw teeth, andpharyngeal teeth;2. Changes in quantitative traits of feeding organ with development, i. e.mouth size (opening),number, density,and length of gill raker, distance betweenthe adjacent gill rakers, number, density and length of lateral protuberances onfiltering lamellae,and distance between lateral protuberances.The following quegtions were also discussed:1. Relationship between feeding mode and feeding function in Tilapia;2. Relationship between development of feeding organ and transition of feeding mode;3. Relationship between changes in quantitative characters of feeding organsand transition of the size-suitability and composition of food:4. Relationship between development of feeding organs and biological technique for Tilapia culture.
