The reproductive cycle of the bay scallop, Argopecten irradians irradians (Lamarck), in a small coastal embayment on Cape Cod, Massachusetts


, : The reproductive cycle of the bay scallop, Argopecten irradians irradians (Lamarck), in a small coastal embayment on Cape Cod, Massachusetts. Estuaries, 64: 431-435

The spawning activity of the bay scallop A. irradians (Lamarck) was monitored from May-Sept. in a small embayment on Cape Cod, Massachusetts and compared with changes in hydrographic conditions. Spawning activity of bay scallops began in May and continued through July with some minor activity occurring during Aug. and Sept. Activity was most closely related to changes in ambient temperature and occurred predominantly before the summer maximum temperature was recorded. As temperatures delcined in the late summer and early fall, increased gametogenic activity was evident. A longer period of spawning activity was observed than was previously reported for New England waters.

Oestrogen is a metabolite of testosterone, but its role in spermatogenesis is ill-defined.
