We used to just fish them out of my friend's dugout in summer and through the ice. At his father's farm where the dugout wasn't as deep he used to drag a net through before freeze up but we'd ice fish for the ones he missed. I think we usually got them all, though 1 year there seemed to be 1 fish in there that wouldn't quite commit. After an aerator was installed in the deeper one they kept some over 2 or 3 years and they were pushing 3 lbs. Shooting fish in a barrel but a riot on a fly rod.
