摘要:

目的 探讨大黄鱼幼鱼鳃的显微和超微结构,为大黄鱼幼鱼的呼吸和对盐度的适应生理提供参考。方法 应用石蜡及超薄切片,采用HE染色,分别在光镜和透射电镜下观察大黄鱼幼鱼鳃的显微和超微结构。结果 大黄鱼幼鱼鳃丝结构和其他硬骨鱼基本相似,鳃丝呈梳状连续排列在鳃弓上,鳃小片紧密排列在鳃丝两侧。鳃小片由上皮细胞、内皮细胞、柱细胞和毛细血管网构成。鳃小片上和鳃小片基部都分布有泌氯细胞,鳃小片基部泌氯细胞数量较多,细胞内具有微小管系统,线粒体数量丰富。 结论 大黄鱼幼鱼鳃结构与其他硬骨鱼基本类似,大黄鱼鳃的结构可能是其对盐度变化有较强适应能力的原因。

Abstract:

Objective  To study the microscopic structure and ultrastructure of gill of juvenile Pseudosciaena croceafor more abundant reference of breathing and salinity adaptation physiology. Methods The microscopic structure and ultrastructure of gill of juvenilePseudosciaena crocea were observed by light and transmission electron microscopic. Results The structures of gill of juvenilePseudosciaena crocea were similar to those of other teleosts, the comb primary filaments lined on the gill, and secondary gill lamellae inlaid on two sides of each filament. Secondary filaments consisted of epithelial cells, endothelial cells, pillar cells and capillary vessel net. Chloride cells were found both in the secondary filaments and the base. In the base of the secondary filaments, the number of chloride cells were more. Inside the cells there were tubular network and abundant mitochondrias. Conclusion The structures of gill of juvenilePseudosciaena crocea were similar to those of other teleosts. The features of the structure of gill maybe can explain whyPseudosciaena croceahave strong adaptability to salinity.
