Thanks George. It does appear that a couple of your male CNBG have smaller operculars than what I would expect to see on mature fish.

Maybe a slightly different opercular shape also, compared to the northern BG's I'm accustomed to seeing....hard to say.

"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.
