With 3/4 acre pond if the perch arent successfully reproducing yet than that is super ideal, hold of on the predators and start your own class this fall if you want to start harvesting. It is possible you could have predominantly female perch in the pond, especially with 'shooters'. reproduction may take awhile, hopefully so in your situation.
You can hold off on the predators until you see bunches of small perch.
Then when you do stock predators I would still consider smallies, cause they are just awesome, you could do some feed trained ones if you want. If you do walleye, you can stock them at any number really, but if you want dont want them to eat your big perch than just simply harvest the ones the grow past 16 inches. Typically the less you stock the faster they will grow. one thing to consider is typically most people are adding walleyes into ponds with already other predators, mainly largemouth bass. without another predator in the pond, typical stocking rates actually should go up for walleyes per acre. 100 per acre I would not consider overstocking anymore in a pond that doesnt already have 100 bass per acre.
random thoughts to consider, sounds like a super fun pond you got going on!!!!! ENJOY and keep us updated.
