| 摘 要： | 黄鳍鲷Sarus latus和尼罗罗非鱼Oreochromis nilotica鳃丝和鳃小片表面都具有规则或不规则分布的环形微嵴、沟状或坑状凹陷及孔洞等结构.黄鳍鲷的鳃丝表面一部分鳃丝表皮凹凸不平,另一部分鳃丝表皮较为平坦.黄鳍鲷和尼罗罗非鱼鳃上皮几种细胞的形态结构及数量分布存在细微的差异.黄鳍鲷的扁平上皮细胞表面观以不规则的六边形为主,或类似菱形的四边形,细胞间界限清楚,而尼罗罗非鱼鳃丝细胞表面的微嵴以形成密集指纹状回路,隆起的微嵴两侧有细小的横突,扁平上皮细胞间排列凹凸不平,形成深沟或凹坑,成为细胞间明确的界线.黄鳍鲷鳃丝表面的氯细胞和粘液细胞数量较多,尼罗罗非鱼鳃丝表面基本上没有观察到氯细胞,粘液细胞很少.黄鳍鲷鳃小片的厚度比尼罗罗非鱼鳃小片的厚.

| Abstract: | Regular and irregular circular microridges,indentations,micropits and crevices were observed in the gill of yellowfin porgy Sparus latus and Nile tilapia Oreochromis niloticus by scanning electron microscopic examination.Some surface of gill filaments of S.latus was rude and the other area was smooth. Morphology and distribution of gill epithelial cells in S.latus and O.niloticus showed some small difference. The limit of pavement epithelium cell in S.latus was well defined by the hexagonal or rhomic quadra... |
