You are correct, overpopulation was probably one of the reasons for the fish kill. But wouldnt it be correct also to assume that a DO crash would kill more than just the overpopulated fish. It seems to me that the lack of oxygen would not be directed only towards the so called overpopulated ones. And the talapia will be gone this fall, which even with a small stocking of 100BG the ratio will be the about the same as it is now. But you may be right, as I am far from being knowledgeable on this matter, which is the reason for my post. I will try to get a better ideal on whats left in the pond, but other than watching them when I feed, what else can I do to determine whats left?
