Okay, here's what I'm seeing:

First photo....see the blue striations below the eye? That looks like a GSF feature to me. Bluegills do not have this feature.

Second photo: See the hint of red border on the bottom of the opercular? Bluegills have an all black tab.

General characteristics are the most telling for me, from years spent handling these fish. Their overall shape, coloration, markings,(lack of vertical stripes) and last but not least, the bulging eyes.

The only thing missing is the coloration on the fins, otherwise they appear solid HBG to me.

"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.
