I have a large number of BG x RES hybrids, and although I have never observed them feeding on the surface, I did have two last year that had stomachs full of pellets, discovered upon filleting. Perhaps they still continue to feed at or near the bottom, in spite of the hybridization.

What other species will be present in the pond, and are you looking for a self-sustaining population?

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.
