50lbs of FHM, say 250 minnows to the pound, for a total of approx 12,500 minnows, in a single compartment on the truck. Somehow, accidentally, 300 Florida strain LMB minnows the same size as the fatheads get mixed in with them, in that same tank.
So for every 41 FHM swimming around in that mass of fish, there is 1 Florida LMB minnow.
Certainly, comparing the fish one at a time would point out some obvious differences. But.....
Since we're exploring all the possibilities, lets' say the fish arrive at dusk, or even after dark, when visibility is not that great. TGW1 says that his FHM were all in the same tank, and were deposited directly into the pond. He didn't hand sort hundreds or thousands of FHM...in truth, I probably wouldn't either.
So, in this hypothetical scenario we have 300 LMB, the same size as the thousands of FHM, loose in a pond with no predators. I would think that the survival rate of the bass would be very high under these circumstances. They grow, and the other fish in the pond become forage for them. They eat and continue to grow fairly rapidly until the forage supply is exhausted, whereupon their growth suffers and they get skinny. All the same size....just skinny.
Once again, I'm not suggesting this is what happened. And while I don't have George's years of experience under my belt, I have learned to never say never, and always keep an open mind. When I'm convinced that something is impossible, is usually when I'm proven wrong.

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.
