| 摘 要： | 对鲻（Mugil cephalus）和鲮（Cirrhina molitorella）的鳃丝表面结构进行了扫描电镜比较观察，结果表明，鲻鳃丝杆状部比鲮粗．鲻鳃小片高度比鲮低；两者鳃丝表面分泌孔洞口径和密度不同；鲻和鲮细胞外被不同，鲻细胞外被稀疏，鲮的则致密复杂；鳃小片细胞和鳃丝表皮细胞的表面形态存在差异，文章还描述了鳃丝表皮形态特异的细胞。

| Abstract: | The gills of seawater fish Gray Mullet (Mugil cephalus) and freshwater fish Mud Carp (Cirrhina molitorella) were observed by scanning electronic microscopy.The differences of gill fine structure were found between the two species of fishes. In C. molitorella ,the shaft of gill filaments is thinner and the gill lamellae are taller than in M.cephalus .The number of the secreting holes on the shaft of the gill filaments in M. cephalus is much more than that in C.molitorella .The morphology of surface cell coat on gill filament shafts in the two species is different, being sparse in gray mullet while being dense and complicated in mud carp. The morphologies the cells on the gill filament shafts and epitheliawere also different. Cells having specific morphology on the epithelial gill lamellae are also described. |
