For our ponds with native gills', I cull all fish that are under 6", both males and females. Male BG over 9" are returned to the ponds, as are females over 10". The males between 6-9" are either kept or released, depending on condition, (Wr). Females between 6-10" are usually culled or kept for dinner, but may be released if they are exceptional, which doesn't happen very often.

HBG on the other hand, are much simpler. Males are always released, provided they are healthy and display no abnormalities, or defects which appear to be impeding their growth. I do see instances of this from time to time, most often in the form of incomplete or misshapen dorsal or caudal fins, which doesn't seem to cause any problems vs. malformed mouth or "cheek" portions which are almost always found on smaller, thinner fish.

Female HBG were always culled in the beginning, but now I tend to release them as well, having observed no instances of successful recruitment, or at least no such fish bigger than fry stage have ever been observed or caught after four years of raising HBG.

"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.
