I've never had a brood pond for any kind of fish, so take this with a grain of salt.

I've stocked 100's of lbs of adult Golden shiners in my main pond, and at other times a few hundred thousand Golden shiner frye in my main pond also (note units. lbs. vs. actual live fish) For whatever reason, I've seen the best recruitment of Golden shiners after the frye stockings.

So, to add to esshups comments, I'd say to also net out a good amount of the frye to the main pond.
