This is in response to the striper bedding thread - would not post asa reply for some reason

As Rich said, stripers don't build beds. They swim upstream, the
female squirts out the eggs in current and the male fertilizes them as
they float along. That is why stripers can't spawn in most reservoirs
- they need many miles of flowing water for their eggs to hatch before
they settle to the bottom and die from being covered by silt. I have
heard it takes about 100 miles of flowing water for the eggs to hatch.
