I think it's partly due to geographic optimization, as in it's often stated that CNBG will grow quicker in southern waters than northern strain will. And, I'll just go ahead and say it....many are convinced that CNBG will outgrow northern fish given the same conditions. it's been "standard knowledge" for a long time. Does that mean it's correct? I don't think so. If it were, shouldn't we be seeing two pound coppers everywhere we look? I've seen Richmond Mill giant bluegills of BOTH strains.

I think there's always a tradeoff somewhere. Coppers grow quicker, but northerns live longer. Both have indeterminate growth.

"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.
