In order to obtain the basic data for the effective seed production of scallops, Patinopecten yessoensis, collected from Yongil Bay, Korea during 1993 and 1994, were treated for spawning induction by means of following five methods, such as serotonin injection, sperm suspension, hydrogen peroxide seawater, temperature rise and ultraviolet-ray irradiated seawater. Data on number of spawned eggs and larval survival until the D-shaped larvae in each spawned female were recorded. The maximum number of eggs spawned and the highest survival rate of D-shaped larvae were obtained at sperm suspension stimulation. Therefore, sperm suspension stimulation was considered to be the most practical of these five treatments for hatchery rearing of scallop.
