It's not so much the general idea of support that will be the issue, it's the NUMBER of fish it will support.

That's why you need an idea of the pounds of fish you intend to harvest, the frequency of the harvest, and the duration of the harvest. Cannot escape the math.

"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.
