Some people don't realize this but HSB are fertile and can back cross back to white bass and striped bass. This is the reason they are illegal to stock in VA. The VDGIF is afraid they will escape the pond, swim their way to the Chesapeake Bay and spawn with wild striped bass and screw the gene pool up. However, few if any ponds would have the correct spawning locations for HSB to successfully pull of a spawn.
