Given suitable spawning structure for them in the pond, pretty much all of them. They prefer cavities with access holes just big enough to slip through while they enter (perhaps so larger CC can't usurp their nest).
Successful recruitment is a different thing, dependent on what other fish are in a pond with them. In the presence of mature populations of BG and LMB (lots of hungry mouths in many sizes) CC eggs, fry, and fingerlings seldom survive to adulthood.
