Pond aeration

I share a 3 acre pond with a neighbor that is anxious to start catching big fish off his dock. Currently we can catch small bass and decent sized blue gill. His idea is to put in an aeration system and to also start feeding the fish. There may be some merit to the idea but I'm not sure that I want to split $9,000 to do so. He's got a quote from a company that would sell the materials for an air pumping station, 8 aerators, and a ton of 5/8 inch tubing. Our shared pond is a bit unusual, this is the Florida panhandle and it's probably a shallow sinkhole that is part of the massive aquafer system that comes out in this area. The water is always very clear, the pond has healthy vegetation including lily pads, and the bottom is sand rather than mud. The water can get hot on a summer day - I've waded in and found water like a hot tub on the surface. It's mostly pretty shallow, the deepest I can find is just over 6 feet, and most is 3 feet or less. With the shallow depth would aeration really help the fish out that much? One concern I've got is that now the fish are probably surviving the hot days by lurking in the 6 foot hole where it is cooler. If we put an aerator in that hole it's going to mix the water and potentially bring warmer water to the bottom. Anybody have pond aeration experience and an opinion for this case?

Another potential problem - this pond is delineated as wetland, is there any problem installing aeration in a protected wetland?
