Realized heritability and response to selection for fecundity, hatching rate and fry/Kg for channel catfish females (Ictalurus punctatus) induced to ovulate and fertilized with blue catfish (Ictalurus furcatus) males for the production of hybrid catfish e

A response to selection for fecundity was observed for both years with realized heritability ranging from 0.10 to 0.42. This trait appears to have additive genetic variation and can be improved via selection. Heritabilities for percent hatch and fry/kg were near zero, and likely cannot be improved via mass selection.
