Any walleye fishery is going to be put and take, if thats okay with you go for it. Perch reproduction can be spotty in ponds with boom and bust years. SMB can reporduce in ponds if they have proper habitate, but they may not be able to find enough forage in low perch years and may not be able to keep perch from stunting in high perch years. Also with three predators in your pond you can kiss your minnows good bye.
I personaly hope to stock my pond with smallies and bgills. I have thought about walleyes added as a bonus fish, but even in my 10 acre pond I don't have any hopes of them spawning.
I wonder if golden shiners would be a good addition to smb/bg pond with bounus walleyes?
