【摘要】 利用组织切片技术 ,对粗糙沼虾的卵子发生和卵巢发育周期进行了组织学研究。根据细胞的大小、细胞核和核仁的大小形态及卵黄积累等情况 ,将卵子发生划分为 4个时期 ,卵原细胞、卵黄合成期的卵母细胞、成熟前期和成熟期。卵黄合成期的卵母细胞又可细划分为 3个时期。粗糙沼虾卵巢发育具有一定的规律性。根据卵巢的大小和颜色及每种雌性生殖细胞在卵巢中所占的比例 ,将卵巢发育划分为 7个时期。并通过卵巢发育规律的探讨 ,对粗糙沼虾的人工养殖提出了合理的建议更多还原

【Abstract】 Using histological sections, this paper studied the histology of oogenesis and ovarian development in M.asperulum. According to the size and morphology of cells, nuclei and nucleoli and the vitelline accumulation, oogenesis may be divided into four phases: the oogonium phase, the oocyte phase during yolk synthesis which can be subdivided into three stages:the premature stage and the mature stage. Ovarian development in M.asperulum follows a definite process. According to the size and color of the ovary as well as the proportion in the ovary of every kind of female germ cell, ovarian development can be divided into seven stages. The author puts forward rational suggestions on techniques for the artificial breeding of M.asperulum.更多还原
