CRB, Don't know if this will be of any help, but in Dwight's pond he has about a half dozen female NP that all seem to grow pretty well. He was lucky and when his 5.1 acre pond was sealed that only females were locked in the pond. We have yet to see any evidence of a male NP. Some other ponds I fish in the area have had well meaning fisherman throw in some live NP, but if there is a combo of males and females and they spawn, it seems to me that you end up with a few larger females, and many small NP we call hammer handles. I imagine this could vary with some pond management, amount of forage, etc. I have a pond behind my home that used to be dominated by LM Bass, Crappie, and Bluegill. Someone planted some NP in there, now it is mostly small crappie and many hammer handles. So just throwing in a few NP messed up the whole pond. Not that I don't like to catch NP, but the small ones aren't good for much. I am a fisherman not a pond specialist, just relaying what I have experienced
