摘　　要：为了解贝氏高原鳅鳃的结构与其功能的关系,同时为其人工养殖积累基础资料,应用光学显微镜和扫描电镜对贝氏高原鳅(Trilophysa bleekeri)鳃的组织结构进行观察。结果表明,鳃耙短钝;鳃丝末端膨大;鳃小片互生排列在鳃丝两侧;鳃丝呼吸面上皮细胞薄,高度血管化;非呼吸面由上皮细胞彼此相连。氯细胞数量较少,多分布在鳃小片基部。表明,贝氏高原鳅的鳃表面形态结构与其呼吸作用、摄食作用等功能相适应。The gill histological structure of Trilophysa bleekeri was observed by optical microscope and scanning electron microscope to study the relationship between gill structure and function and to provide the scientific basis for its artificial culture.The results show that the characteristics of the gill structure includes short and dull gill rakers,expanded gill filament terminal,gill lamellae arranged on both sides of gill filament,thin epithelial cells with highly vascularization on the respiratory surface of gill filament,mutual linkage of epithelial cells on the non-respiratory surface of gill filament and less chloride cells on the bottom of gill lamellae,which indicates that the gill surface morphological structure of Trilophysa bleekeri is suitable to its respiratory and ingestion function.
