本文根据四明湖水库翘嘴红鲌Erythroculter ilishaeformis Bleeker卵巢成熟度等级,成熟系数和周年组织学资料,对卵巢各成熟期中的卵母细胞形态结构及其演替进行了细胞学描述和探讨;判定该水库翘嘴红鲌的产卵期为6月下旬至9月上旬;成熟卵至少分两批产出,属分批产卵类型。
Based on the ovarian maturity grade, maturation coefficient and histological data of Erythroculter ilishaeformis Bleeker, the morphological changes and succession of oocytes in each stage of ovary were described and discussed. The reservoir spawning period is from late June to early September; the mature eggs are produced in at least two batches, belonging to the type of spawning in batches.
