根据性腺外部特征和显微观察结果,将砂海螂(Mya arenaria)的性腺发育过程分为增殖期、生长期、成熟期、排放期和休止期5个阶段。芝罘湾砂海螂满1年性成熟,1年1个生殖周期,每年有2个繁殖高峰期,分别在5月上旬到6月上旬和8月下旬到10月上旬。
According to the characteristics of gonads and the microscopic observation, the process of gonadal development of Mya arenaria was divided into five stages: proliferative phase, growth phase, maturation phase, discharge phase and resting phase. Chibi Bay sand seaman full one year of sexual maturity, 1 year 1 reproductive cycle, annual breeding peak of 2, respectively, in early May to early June and late August to early October.
