克氏原螯虾雌性生殖系统发育及组织结构观察
Study on Development of Female Reproductive System and Histological Structure of Procambarus clarkii
摘要
Abstract
The development of female reproductive system and histological structure of Procambarus clarkii were studied by u-sing appearance anatomic observation and histological method. The results showed that the female reproductive system of P. clarkii consisted of ovaries and oviduct, and ovaries were Y-shaped. Egg chambers were distributed in ovaries at their earlier develop-ment stage, and the oocytes were reproduced in egg chamber. The oogenesis experienced the following four phases: oogoniums, pre-yolk-synthesis oocytes,yolk-synthesis oocytes,and mature oocytes. The ovary development of P. clarkii could be divided in-to five stages: stageⅠ,stageⅡ,stageⅢ(including early stage,middle stage,and later stage),stageⅣ,and stageⅤ. The ooplasms contained smooth endoplasmic reticulum, dense small-particulate matter and mitochondria, which were involved in the synthesis of yolk granules. The characteristics of black ovaries,filling oocytes with egg yolks,nucleus disappearing,and oocyte-follicular cell separation were used as the mature signs of this crayfish. The gonadal development of P. clarkii individuals was not synchronized, they spawned once a year, and the population had two spawning peak periods each year: from September to Octo-ber, and from April to May.关键词
