Forgive me, I didn't go back through your posts to see exactly what your goals are, and what you would like to accomplish. When you say eating, are you talking recreational eating once in awhile, or counting on these fish to supply a good portion of the menu quite regularly?

You can stock the HBG first, but like snrub stated, if you want BG later you will want >3" fish. That shouldn't be a problem to source. What else is going into this pond by way of predators? Aeration and feed will boost the fish numbers, but water quality issues and vegetation will probably be your next hurdles. You do know that HBG are usually managed as a put and take fish?

"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
