Now I think those photos Ewest posted are easy.... scale tipping, bright copper band, round body dynamic vs. more elongated, very dark breast area, larger opercular, (although I beginning to wonder if northern males have a more pronounced flap?),

AND, there's a reference in the photos that allows one to gauge size/maturity. I wouldn't hesitate to call those fish males. If that is incorrect, could someone please help me in determining where I've gone off track???

"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.
