Abstract

The cephalic, middle and posterior regions of the testes in Garra gotyla are identical in structure and function. The spermatogenetic activity starts in the month of October reaching its peak in April and May. Spawning takes place in June and July followed by a brief resting period. Spermiation appears to be intermittent. Six stages of spermatogenesis have been described. New crop of germ cells appears to arise from the resting spermatogonia. Both the interstitial and the lobule boundary cells were observed. The gonosomatic index shows correlatation between the rise in water temperature and the volume of the testes.

摘要

印度墨头鱼睾丸的头部、中部和后部在结构和功能上是相同的。精子发生活动于10月开始,在4月和5月达到高峰。产卵发生在6月和7月,随后是短暂的静止期。精子排放似乎是间歇性的。已经描述了精子发生的六个阶段。新一批生殖细胞似乎源自静止的精原细胞。观察到了间质细胞和小叶边界细胞。性腺指数显示水温升高与睾丸体积之间存在相关性。
