I've noticed that when I target RES I will usually catch several RES/BG hybrids. (fishing very near bottom). However, I see the hybrids taking pellets off the surface with the BG, also. Very striking fish, appearance wise, and outstanding fighters on light tackle.

"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.
