Lots of variation in CNBG. Still the debate goes on as to how many subspecies there might be, and some hatcheries prefer to source their brood fish from particular geographic regions in order to try and capitalize on particular traits.

All CNBG are not created equal, as George Glazener might've said. Love the giant coppers from southern Cali.

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.
