In my opinion the only two reasons not to stock them would be the cost and having to use a leader when you fish. The average pond owner may not be comfortable paying for a fish about twice the price as a LMB and have that fish not reproduce for them. I realize walleye are expensive to buy in the store or at a restaurant, but that could be one explanation. Also pond owners may not want to have to use a leader everytime they fish in fear of having a big walleye get on their line and cut it. Since leaders do limit a lures action.
I personally love fishing for and eating walleye. My only question is I like to swim in my pond and though I highly doubt they would bite me, my friends and family may be afraid to swim with walleye in the pond.
