Thanks Snipe!
I think my closest supplier has a 100 fish minimal order. I might be able to find some other MI pond-meisters to share. Maybe if I show up they will sell me less than a full order if we get near the end of the fish season.

I have aeration and some windy days but the area is sheltered on E and W sides by trees and we get winds from the west.

I would attempt a fall stocking based. I wish the pond was deeper but who doesn't? Too hard to fix now.

Thanks on the tip to look for a 6" size slot.
