Abstract
InAlcichthys alcicornis, a sculpin copulating in conjunction with paternal care, the genetic relation between males and egg masses they guard was investigated using polymorphism of an isozyme. At least 3 out of the 10 egg masses investigated were not genetically related with the guarding males. In these 3 cases, the female parents must have copulated with males other than the guarding males. It was hypothesized that males take care of non-kin eggs for the opportunity to fertilize the next clutch females will produce.
