HBG are not sterile, and they can reproduce. The first generation hybrids normally purchased as stockers from a hatchery (F1), should be around 95% male. This is what accounts for their limited reproductive potential.

As far as HSB in parts of Texas, there are many members here far better equipped to advise you than myself. I will say that HSB are swimming in a great many Texas ponds, but I'm just not familiar enough with the geography.

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.
