根据生殖细胞发育的宏观和组织切片观察以及各期生殖细胞在滤泡中所占的比例，泥蚶的生殖腺发育过程分为增殖期、生长期、成熟期、排放期和休止期五个阶段。按肥满度的变化并结合性腺组织切片确定，泥蚶的性晚发育在青岛海区一年一个周期。繁殖期在７月上旬至８月下旬，繁殖盛期在７月中旬至８月中旬。至少有二次集中排放过程。 According to the macroscopic and histological sections of germ cell development and the proportion of germ cells in the follicles, the gonadal development process is divided into five stages: proliferative phase, growth phase, mature phase, discharge phase and resting phase. According to changes in fat fullness and combined with gonadal tissue slices to determine the late development of the muddy sea in Qingdao area a year cycle. Breeding period from early July to late August, breeding peak in mid-July to mid-August. At least two times to concentrate emissions process.
