I would call the first photo a female BG, the next two male BG, and the last is a HBG. If you never catch a crappie in that 1/4 acre pond, I would consider myself fortunate. The FHM may not last too long in an already established pond. Keep track of the numbers of CC, and once they reach the size you want, I would remove every one I catch. Same with the crappie, if they do put in an appearance.

Do you intend to feed this pond?

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.
