The courtship activity of male F2 descendants of irradiated and control guppies, Poecilia reticulata, of the inbred strain Istanbul was compared. The results of Spieser and Schröder (1978), who found a decrease in courtship activity of descendants of irradiated guppies, were confirmed under more natural conditions.
