摘　　要： 对鳜精巢的组织学结构和超微结构进行观察.鳜精巢呈叶型结构,由精原细胞、初级精母细胞、次级精母细胞、精细胞、成熟精子等生殖细胞和支持细胞、间质细胞、边界细胞、类肌细胞、成纤维细胞、内皮细胞等非生殖细胞组成.鳜精子形成过程,精细胞大致经历了鞭毛发生,核质凝缩及核位置的改变,线粒体迁移等过程.鳜成熟精子无顶体结构,头短而圆,主要为核占据,核凹窝发达,尾细长,具侧鳍,尾部轴丝为"9+2"结构. The histological structure and ultrastructure of the testes in Siniperca chuatsi were studied with light and transmission electron microscopy. The testes has a lobular type of organization and consists of spermatogonia, primary spermatocytes, second spermatocytes, spermatid, sperm and Sertoli cells, Leydig cells, boundary cells, Myoid cells, fibroblasts, endothelial cells, which composed of germ cells and interstitial cells. There are four developmental stages in spermiogenesis: the young spermatid; axoneme growth; condensation and rotation of nucleus; migration of mitochondria. Matured sperm is composed of the haed, midpiece and tail. The nuclear fossa is very developed. The tail is very long, contaning lateral fins. The axonemes have a '9+2' pattern.
