While examining the survival rates of eggs in a splake brood stock, it was found that the survival of progeny from egg to the time of yolksac absorption increased as the age of the parents increased.Examination of spawning success of individual fish in another brood stock indicated that the increased survival rate was related to the female parent. There was no effect of the female parent on survival from eggs to eyed eggs, but there was a significant effect of survival from eyed eggs to hatch and from hatch to the time of yolksac absorption.
