You could try counting the soft rays on the anal fin. I THINK I remember that coppernose should have 12 rays, while northern strain will have 11.
Coppernose usually have wider vertical stripes than northerns also.
"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.
