中文摘要:
      根据波纹巴非蛤生殖细胞发育的规律和它们在滤泡中所占的比例,把波纹巴非蛤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。根据相对重量、鲜出肉率、干出肉率等指标的变化,并结合性腺的组织切片确定,波纹巴非蛤的性腺发育在闽南海区一年—个周期。繁殖期在5月中旬——10月下旬,但其繁殖高峰则有两次,分别在5月下旬和10月上旬。这表明波纹巴非蛤的成熟期和生殖期是相互重叠的。此外还观察到该种有雌雄同体现象。
英文摘要:
      The reproductive cycle of the clam Paphia undulata (Born) has beenstudied. According to the cyctological characteristics of the developing germ cellsand the relative amount of germ cells, the annual cycle of maturation could be divi-ded into the following five stage: (1) proliferating stage,March to April; (2) grew-ing stage,April to May; (3) maturing stage, May to October; (4) spawning stage,May to October; (5) resting stage, November to February of next year. The spwaning season started from the middle of May to the end of October.There were two spawning peak in a year, i. e. the end of May and early October,while the matured sexual cells discharged in batches. Temperature was the mostimportant factor for influencing the maturation of the gonad and the spawningperiod of the clam. A hermaphrodite specimen was discovered and examined.
