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4.5～488mm的鳙标本540余尾.描述了鳙鳃耙和鳃耙侧突起、腭褶、鳃耙管等滤食器官的形态学特点和数量性状在胚后发育中的变化规律;论述了鳙滤食器官发育与摄食方式的转化、摄食器官的数量性状发育与适口食物和食物组成的转变,鳃耙间距在胚后发育中的变化和鳙滤食器官发育与苗种培育阶段的划分和饲养生物学技术措施。为制定培育鳙苗种和饲养食用鱼生物学技术措施提供了理论依据。
The developmental morphology of the filtering apparatus from big-head carp (Aristichthys nobilis) varying from 4.3mm to 448mm in total length (n>540) was observed by dissection, slide sections, light and scanning electron microscopy. The following aspects were described: 1.developmental characteristics of gill rakers, suprabranchial organ and palatal organ including the formation of gill rakers and branchial sieve, differentiation of wide gill rakers and narrow gill rakers and develomment of palatal organ and suprabrachial organj. 2. changes in quantitative traits with filtering apparatus development, e. g. mouth size (opening), number, density, and length of a gill raker both inside and outside suprabranchial organ, distance between the adjacent gill rakers, number, density, and length of lateral protuberances on filtering lamellae, and distances between the lateral protuberances.Also, more questions were discussed about: 1.relationship between the develop' ment of filtering apparatus and transition of feeding behaviour. 2. relationship between changes in quantitative characters of filtering apparatus. 3. changes in distances between the adjacent gill rakers during post-larval development. 4. relationship between development of filtering apparatus and biological technique of fry rearing and fingerling culture.
