摘　　要：应用光学显微镜、扫描电镜和透射电镜对珠江口池塘养殖梭鱼Liza haematocheila鳃的组织结构、表面形态特征及鳃小片超微结构进行了观察。结果表明梭鱼具有4对鳃,每个鳃由鳃弓、鳃丝、鳃小片和鳃耙组成。梭鱼鳃丝和鳃小片的表面结构和超微结构与其他硬骨鱼类的基本相似,鳃丝表面分布有众多规则或不规则的环形微嵴、沟、坑、孔等结构。鳃丝分为呼吸区和非呼吸区,呼吸区较为平滑,上皮细胞表面无微嵴,呈皱褶状;非呼吸区分布有沟、坑、孔等结构,上皮细胞有较规则的指纹状微嵴。鳃小片是最主要的呼吸场所,由基膜、上皮细胞、内皮细胞、柱细胞和毛细血管网组成。泌氯细胞主要分布在鳃小片基部,并有开口通往外界。本文还探讨了梭鱼鳃的结构与其功能的密切关系。The histological, surface and internal fine structures of gill of Liza haematocheila were investigated using light, scanning and transmission electron microscopy. The results showed that there were 4 pairs of holobraneh in Liza haemato- cheilu, and each gill filament was consisted by branchial arch, primary filament, secondary filament and gill raker. The sur- face structure and uhrastructure of gill filaments and secondary gill lamellae of L. haematocheila were similar to other tele- osts. The surface of primary filament had various features such as regular or irregular circular mieroridges, indentations, mi- cropits and crevices. The primary filaments were separated into respiratory area and non-respiratory area. The respiratory ar- ea of filaments was smooth with no microridge but folded on the epithelial cells membrane. Various features such as indenta- tions, micropits and crevices were observed on non-respiratory area of filaments with regular fingerprint shape mieroridges on epithelial cells. The secondary filaments, which functioned as the main organ of respiratory, were consisted of basement membranes, epithelial cells, endothelial cells, pillar cells and capillary vessels. Chloride cells were mainly found in base part of secondary filament, and they often seemed to be open at the surface between adjacent epithelial cells. The relation- ship between the structure and function of fish gill in L. haematocheila was also discussed.
