人工养殖曼氏无针乌贼生殖系统的解剖学与组织学研究

Anatomy and histology of reproductive system in cultured Sepiella maindroni

采用解剖学和组织切片技术对人工养殖曼氏无针乌贼(Sepiella maindroni)成熟个体的生殖系统进行观察。曼氏无针乌贼为雌雄异体,其雄性生殖系统包括精巢、输精管、精囊(精囊I、精囊II、精囊II的桃核体和精囊III)、副性腺和精荚囊;雌性生殖系统包括卵巢、输卵管、输卵管腺以及附属腺(缠卵腺和副缠卵腺)。光镜下,精巢属于小叶型,由精巢壁和实质部分组成,实质部分由精小叶和小叶间质构成;卵巢呈葡萄串状,由卵巢壁、不同时相的卵母细胞和卵巢基质构成。

The reproductive system of bred cuttlefish, Sepiella maindroni was observed by using anatomical and histological methods. The results are as follows. Sepiella maindroni is gonochorism. Its male genital system consists of spermary, spermaduct, vesicular seminalis （including vesicular seminalis Ⅰ, vesicular seminalis Ⅱ, the peach nucleus bod of vesicular seminalis Ⅱ and vesicular seminalis Ⅲ）, prostate gland and spermatophore sac and its female genital system consists of ovary, oviduct, albumen gland and affiliated gland （including nidamental gland and accessory nidamental gland）. According to the light microscope, the lobular type of spermary consists of spermary wall and parenchyma, and the spermary parenchyma consists of seminiferous lobules and interlobular septum. The ovary looks like a bunch of grape, consisting of ovarian wall, different periods of oocytes and its parenchyma. [Journal of Fishery Sciences of China, 2008, 15 （1） ： 63-72]
