摘要
根据性腺组织学观察,对雌性大弹涂鱼卵细胞发育的5个时相作了形态特征的描述和探讨,并将其卵巢划分为6个发育期。本文还观察到第4时相晚期外卵膜上的丝状物,并对产卵类型作了阐述。
Based on the results of histological observation of gonadal development in female mudskipper (Boleophthalmus pectinirostris),the morphological characters of five phases of the oogenesis, including oogonia, monolayer follicles, yolk and adipose vesicles accumulated, yolk fllled and ripe oocytes, are described. According to the composition variation of the egg development in the ovary, the maturation of female gonad can be derided into six stages(Ⅰ—Ⅵ), namely, juvenile, immature or recovering spent, maturing,nearly ripe, ripe and running,and spent stages. There are silky substances secreted from the follicle cells at the late fourth phase of the oocytes development. After ripe eggs have been released from the ovary, these silky substances scatter and become adhesive threads. The development of oocytes of the fish belongs to group synchronism, so the female spawn once annually during the spawning season.
