Time will tell if the pond gets deeper due to aeration. At least you know a pre-aeration depth.
F-n-C has good comments about what are the existing fishes in the pond. Have you tried sampling by angling, seining or trapping????. The next time AquaDoc arrives they could easily do a simple fish sampling if they are asked before they arrive and can plan to bring a seine or fish traps. It is easy to get small hooks size 10 or 12 and use small pieces of worms with a slender bobber to check to see if any small fish are present. The methods works well to catch many species of fish as small as 3".
