There are only a very few impoundments where striped bass can naturally reproduce. David is right, striped bass eggs are just a little heavier than water, so they tend to not completely sink but kind of bounce along the bottom. When the current dies, the eggs sink and silt up and die.

So you basically need a river running into an impoundment that is long enough to support striped bass spawning far enough up river to allow the eggs to then float downstream long enough to hatch. Not many impooundments out there like that. Striped bass can and will thrive in complete freshwater and can and will spawn in complete freshwater.

Hybrid stripers are more tolerant of higher water temperatures and lower DO. Just like sub adult striped bass are tolerant of the same conditions. It seems that once striped bass get over about 8 lbs they become much less tolerant to high water temps and low DO. Even large hybrid stripers prefer cooler waters with higher DOs.

Ponds are stocked with HSB over striped bass because HSB are more tolerant of higher water temps and low DO. In order to have a successful striped bass fishery, you need a lake that is going to have a classic "two story" fishery. This requires a rather large body of water, far beyond the average and not so average pond owner...
