Perhaps Setterguy can chime in on how many YP he harvests, at will, per year in a SMB pond I stocked for him several years ago. I stocked 1500 3-6" YP, 20# Fathead Minnow and 25# Golden Shiner. Later we added 100 4-6" SMB. He does use a feeder, throwing Optimal and/or Purina Aquamax, and harvests several 1 pound YP a year and catches smallies in excess of 4 pounds
