How long from the time the pond had water in it until it was stocked? That bass went 3 pounds....how large would it have been to be physically carried by a kingfisher? I think that bass was already good sized when it arrived.

Accidental drops of a small, impaled fish that probably didn't survive....I can see that.

"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.
