Rome wasn't built in a day, but the math works...there are many ways to play the numbers, I'm not disagreeing with your concept of tilapia. The "real world" doesn't work like your projected numbers, my post was to point out your numbers are fictional. Did you see the immediate response to achieve what you posted ?

I remember you reporting a minor dieoff of tilapia in a pond where no predators were present...given your original computations, I would have expected quite a few more \:D

p.s. In closing, you should really reply to Bob-O's post about not stocking BG in his predator pond in your other thread, I would hate for him to make an a monumental mistake.
