While Bill's comment on HSB not spawning in the pond is 99.9% correct, don't assume that they are sterile because they are not. The HSB just do not have the correct spawning habitat for the eggs to remain viable until they hatch.
esshup,
Have you ever heard (or read) of a successful spawn of HSB in a pond?
What is the limiting condition that defeats the spawning effort? Might someone's pond be close to favorable conditions?
anthropic is correct. Striped Bass eggs float, and have to float in well oxygenated water (flowing or moving water) for roughly 30-70 hours, depending on the water temp. If they reach shore, they will get silted over and die. So, flowing water is needed to keep them moving. I know of only one pond in the USA where the pond owner has reproduction from the Hybrid Striped Bass. That is the pond owned by the creator of Stubby Steve's Pellets. His pond has a very long fetch that ends up on limestone riprap and he will occasionally get some viable HSB eggs hatch if the weather and wind conditions are "just right".
