My grandfather stocked a pretty decent sized pond on our ranch with yellow perch many years ago ( he estimates 25 plus). I tried ice fishing it this winter and found that the fish have become stunted (all 3-6 inches). The lake is around 80 acres and has depth up to 25 feet. And has hundreds of dead trees scattered throughout. I would like to establish a crappie and walleye population but am unsure how to do so with the excess of perch. PLEASE HELP!!
