中文摘要：以2月龄至2龄的长鳍裸颊鲷精巢为材料,采用常规石蜡切片方法,光镜下观察长鳍裸颊鲷精巢发生、发育至成熟的过程。结果表明,长鳍裸颊鲷的精巢为叶型,位于腹腔后上方,尾部没有合并。精巢发育分为6个时期。精细胞的发育过程也分为6个时期。精细胞的发育由同步到不同步,最后又同步的变化规律。为长鳍裸颊鲷分批排精提供了保障。

外文摘要：In this experiment, gonadogenesis and development was histologically observed in testis of Leth- rinus erythropterus from 2 months old to 2 years old under a light microscope. The results showed that the testis was leaf in shape and located in the abdominal cavity, without connection in caudal portion. Testicu- lar development is divided into six stages： I , testis was specific and looked like a thin line; Ⅱ , testis in- creased slightly with wavy edges; Ⅲ, testis was flat, whose blood vessels were observed without connec- tion in caudal portion; IV, testis occupied more than 1/2 in abdominal cavity; V , testis was milky white in color, more than 2/3 of abdominal cavity; the volume of Ⅵ, testis atrophied. The entire process of sperm cell development of L. erythropterus was broadly divided into six periods： multiplication of spermatogonial cells,growth of spermatocytes, maturation of spermatocytes, emergence of spermatoblasts, maturation of spermatozoon, and degeneration of spermatozoon. During the development of sperm, phenomenon ap- peared in batches from the synchronization to unsynchronization and then the synchronization, which makes the fish in batches ejaculation provide more chances for fertilization.
