Rusto,
I don't know much at all about paddlefish.
I did find a fascinating article. Apparently they do thrive in ponds. And there is a fish supplier in Missouri that stocks them in people's ponds and then comes back a few years later to harvest the caviar.
It is Osage Catfisheries. I think their facility is located by the Lake of the Ozarks.
