鱼类的摄食行为是多种摄食器官共同作用的结果。不同食性鱼类在摄食行为中起主导作用的摄食器官是不同的;杂食性鱼类起主要作用的是咽齿和角质垫,而肉食性鱼类起主要作用的是咽齿、角质垫和牙齿。为给鱼类摄食方式与摄食器官关系的研究提供科学理论依据,运用大体解剖、电子游标卡尺测定及肉眼观察等方法测定5种常规淡水鱼的口径、鳃耙和咽喉齿等摄食器官。论述5种常规淡水鱼摄食方式与摄食器官的关系,充分体现鱼类的结构与功能相统一的生理特征。
The feeding behavior of fish is the result of the interaction of multiple feeding organs. Different feeding fish play a dominant role in feeding behavior of feeding organs; omnivorous fish play a major role in the pharynx and cuticle, while carnivorous fish play a major role in the pharynx, cuticle and teeth . In order to provide a scientific basis for the research on the relationship between fish feeding patterns and feeding organs, the feeding organs such as caliber, gill rakers and pharynx of five kinds of freshwater fish were determined by gross anatomy, electronic vernier caliper measurement and macroscopic observation. Discusses five kinds of freshwater fish feeding habits and feeding relationship, fully reflect the fish structure and function of the unity of the physiological characteristics.
