I have a camp on a 7.5 ac pond, which I had heard had crappie in it, and decided on a whim to dunk some minnows back in early March. First one was 2 lbs 3 oz, and a bunch more after that, between 1.0 and 2.0. All black crappie. Subsequent trips to the pond yielded more of the same plus some smaller ones in the 9 - 10 inch range. The pond has a lot of threadfin shad, and gets fertilized regularly when water temp is > 60 f. I suspect the healthy shad population is key to the nice fat black crappie. We also have a good number of large LMB (4+ lbs) which I suspect helps keep the small crappie at bay. All of this to say that a relatively small pond CAN support a decent crappie fishery.
