How would you exterminate hundreds of thousands of fish and get rid of them?

I cast net often and feed the birds. I caught 500 in 1.5 hours of cast netting. I think I can do that every day for a year and it might make a dent. I relocated some to small pond for the birds to feast on.

I have a 4.5 acre pond in central Florida, retention pond. It drops off steep on all sides down to 26ft. There is not much shallow water. Currently there is very few bass in it. It is overloaded with tilapia. I recently put a lot of structure in it as there was none, clean bottom. I put 500 2" bass in it 2 years ago and I have not seen them in over a year. I have seen a few and caught one nice fat young fish. I have caught about 30 bass from the 1-3 lb range from other locations and added them to my pond. How do I get control of the tilapia population? I hope the bass will eventually control the tilapia population. How do I ensure the baby bass get past the point of being prey and become predators?
