Too early to claim success, but my pond is just under an acre. Stocked FHM, RES, GSH, and LCS. Then added YP and papershell crayfish, followed by 10 SMB in each of two consecutive years (20 total). Lots of FHM, LCS, and YP reproduction and pulled a single SMB last year that had grown larger than I thought was possible after one growing season. I have not fished the pond since then, but my neighbor harvested a keeper YP through the ice last winter. Still have plenty of small fish swimming near the edges. Just too much to do adding more wildlife habitat to our place to stop and fish. Deer hunting is another story! Everything goes on hold October 1st!
