I'm with Dave in that water clarity may be the culprit. Cooler water also tends to subdue coloration. Do you have the hybrid gills in the same pond as the native?

Go fishing. It's good for you.

"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.
