摘　　要：[目的]初步了解鱼类消化系统形态结构与食性的关系。[方法]以4种鲤形目鱼类为材料,对其消化系统进行了解剖与比较分析。[结果]鲢鱼的消化道最长,是体长的4.084倍,而黄颡鱼的消化道最短,是体长的0.850倍。[结论]不同鲤形目鱼类消化道的形态上存在很大的差异,消化系统各部分特点与食性及食物种类相适应的。[Objective] The research aimed to initially understand the relationship between the digestive systems morphologic structure and the feeding habits of fishes.[Method] Taking four species of Cypriniformes as the experimental materials,the digestive systems were anatomized and compared.[Result] The digestive tract of Hypophthalmichthys molitrix was the longest,4.084 times as its body length.While the digestive tract of Pelteobagrus fulvidraco was the shortest,0.850 times as its body length.[Conclusion] The morphology of the digestive tract of different species of Cypriniformes had great differences.The characteristics of different parts of the digestive system was fit to the feeding habits and food kinds.
