毛蚶卵巢发育的形态学与组织学研究

A Morphologic and Histological Study on the Ovary of Scapharca Subcrenata

根据毛蚶卵巢的组织学和外部形态特征,可将卵巢发育分为5 个时期:增殖期、生长期、成熟期、排放期和休止期。毛蚶卵巢发育在连云港海区为一年一个周期,产卵期为7 月至9 月,产卵高峰期在7月下旬至8月中旬,为分批产卵类型。

According to the morphologic and histological characteristics, the ovarian development of Scapharca subcrenata can be divided into five phases: the proliferating, growing stage, maturing stage, spawning and resting stage. The ovarian development of Scapharca subcrenata has only one cycle every year in Lianyungang region. Its spawning period is from July to September and the oviferous peak is from the last ten days of July to mid August. The spawn is in batches.
