| 摘 要： | 每月定时取人工养殖子代银鲳(Pampus argenteus)样本,采用常规石蜡切片技术对样本卵巢发育情况进行周年观察。期间共采集到雌性银鲳样本92尾,叉长范围为113.1~185.7 mm,体质量33.6~187.5 g。按照各个时相形态特征和卵巢周年变化情况,养殖银鲳卵子发生分为6个时相,卵巢发育分为6个时期。研究表明,养殖条件下的银鲳群体与野生群体卵巢发育的组织学结构无明显差异,且繁殖季节基本一致,但养殖群体卵巢成熟系数明显低于野生群体。推测养殖过程中温度、光照和营养等因素对银鲳性腺发育和成熟具有较大的影响。本研究旨在为银鲳人工繁育研究提供基础科学支持。

| Abstract: | The present study describes the morphology, histology and annual cyclical changes in the ovaries of the cultured silver pomfret, Pampus argenteus. The ovary development was divided into six stages, as were the changes in the oocytes of the female. Cultured Pampus argenteus populations have a similar ovarian structure, development process and breeding season to wild populations. However, the gonadosomatic index in cultured populations are obviously higher than that of wild populations, which infers that factors such as temperature, photoperiod and nutrition in cultured environments have a great effect on the development and maturation of the gonad in P. argenteus. The present study provides basic information for the artificial breeding of this species. |
