1.亚种A. I.来自佛罗里达鳄鱼港的同心鳄，在夏季温度最高的7月底达到成熟，并在8月初开始产卵，因为温度开始下降。冬季温度减缓了佛罗里达扇贝种群的性腺发育。在冬季，在23.0 ± 1.0° C的高温下刺激扇贝成熟。在26天内。实验室中的成熟扇贝在一年中的不同月份对高温的反应是产卵。亚种A. I.来自马萨诸塞州和A. I.来自佛罗里达和北卡罗来纳州的同心圆线虫在成熟和产卵的温度要求上显示出差异。与南部亚种相比，哈特拉斯角北部的亚种在较低的温度下繁殖。两个亚种的产卵期并不重叠。
1. Subspecies A. i. concentricus from Alligator Harbor, Florida, reaches maturity towards the end of July when the summer temperatures are maximum and commences spawning early in August as the temperatures begin to decrease.2. Winter temperatures slow gonadal development of a Florida population of scallops. During winter, scallops were stimulated to maturity at elevated temperature of 23.0 ± 1.0° C. in 26 days.3. Matured scallops maintained in the laboratory spawned in response to elevated temperature during different months of the year.4. The subspecies A. i. irradians from Massachusetts and A. i. concentricus from Florida and North Carolina show differences in temperature requirements for maturation and spawning. The subspecies north of Cape Hatteras reproduce at lower temperatures as compared with the southern subspecies. The spawning of both the subspecies does not overlap.
