To me, it looks like a mix of coppernose bluegill(CNBG), and Hybrid bluegill(HBG), with some green sunfish(or degraded HBG)....some of the bluegill appear to show northern characteristics as well. Quite the mix.

If there's no other BOW that feeds into the ponds,(that would reintroduce undesired species), then starting over is looking more attractive all the time.

I would still verify depth first.

"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.
