中文摘要:
      本文对极边扁咽齿鱼,黄河裸裂尻鱼、花斑裸鲤和厚唇重唇鱼进行了食性分析和脑的形态结构观察,并对脑结构和食性的关系作了初步探讨。认为这四种鱼类属于底层味觉食性鱼类,其中极边扁咽齿鱼和黄河裸裂尻鱼主要靠口腔、腭部味蕾觅食泥土和藻类,迷叶发达;厚唇重唇鱼主要靠触须寻找甲壳类为主的水底昆虫,面叶和小脑发达;花斑裸鲤的脑结构特征与其杂食性相适应。
英文摘要:
      This paper deals with the analysis of feeding hadits and obeservationon the structure in brains of P. extremrs, S. pylzovi, G. eckloni and G. pachycheilus. The correlation between brain structure and feeding habits was discussed. These fourfish belong to bottom feeders with the aid of taste sense. P. extremus and S pylzovifeed on mud and algae mainly with the aid of taste buds in pharynx. The vagal lobesof their brains developed very prominently. G. pachyeilus uses mainly its barbels tosort out aquatic insects, especially crustacean. Its facial lobe and cerabellum of the.brain are largu. The brain of G. ecklcni fits to ils omnivorous feedind habits.
