本文对东海银鲳的卵巢周年变化、卵母细胞发育等作了研究。结果表明,东海银鲳的繁殖期在5—6月。繁殖期过后,其卵巢发育长期处在重复发育的Ⅱ′期,并在此期过冬,至翌年3月下旬卵巢再次发育。在卵母细胞发育早期,胞质内便出现油球结构,胞质有分层现象。卵母细胞发育至大生长期晚期后,其放射带减薄且渐消失。待卵母细胞充分发育时,仅存单层的胶质膜结构。银鲳为短期分批产卵类型。
In this paper, the annual changes of the ovary and the development of oocytes in the East China Sea were studied. The results show that the breeding season of silver flesh in the East China Sea is from May to June. After the breeding period, its ovary development in long-term repeat development of Ⅱ ’period, and in the winter, to the next year in late March ovarian development. In the early stages of oocyte development, the structure of the oily sphere appears in the cytoplasm, and the cytoplasm has stratification. Oocyte development to the late late growth stage, the radioactive zone thinning and gradually disappear. Oocyte to be fully developed, only the single layer of the glial membrane structure. Silver 鲳 short-term batches spawning type.
