Hello and welcome from another new member! How often your friend would like to eat fish from his pond will likely determine whether or not his goals are attainable. I would think that in a pond that size supplemental feeding would be needed to harvest fish on a regular basis and periodic restocking may also be needed. One option may be to stock one pond with bass and bluegill from which fish could occaisionally be removed to eat and to stock the other one with channel catfish to be harvested on a more regular basis. I'm not sure what type of climate you have up there but there are other options for food fish as well, trout are pretty popular with some people and tilapia seem to have a following here as well. Any of those three fish being stocked in a pond that size would benefit greatly from being fed, especially if there will be a heavy harvest. Someone else will be able to provide more detailed info.
