Norm,
I'll take a shot...
I love small ponds. They can really surprise with what they can produce both in size and numbers. I feel that one can have good LMB fishing in a small pond, but only on an intermittment basis, meaning too much fishing pressure can spoil the fun. BG fishing in a small pond can be spectacular, but again even the BG can suffer too much fishing pressure.
All ponds benefit from aeration. Feeding w/o aeration can be problematic depending on how much or how little flushing action the pond receives either from rain or other sources.
Another possible small pond stocking strategy is the GG and HSB combo but since I have only had a few months experience with that combo, can't say for sure how it will turn out...but the early returns are very positive.
Small ponds are easy to manage, especially if you can add a few Tilapia each year to control algae and provide supplemental forage. One grass carp or two will provide all the weed control you need. So that with the right fish, management is a snap and more time can be spent enjoying the pond, which after all is what its all about.
