Remember this guys it takes a cannel to be about 6 to 7 lbs to really become predatious as Bass. It takes a lot of time and expense to grow 100 channels to this size! While bass after only about 5 to 6 months they are already good preditors. This is far less effort to do and is much much cheaper as well.

It seems very possible to make channels the only preditor in your lake or pond, but the real question is why? If your goals were trophy channel cats, I would still start off with a good bass bream mix. Bass and bream can only help in raising big channels because channels will sooner or later start eating the Bass and bream as forage!!...think about it.
Like Greg said before, its all about your goals..
