In talking with the Purina Rep at the Conference, he said that from Fingerling to about 2#, the FCR on LMB being fed their food is right around 1.7.
Humbug!

That's a best case scenario in a lab where no feed is wasted as in fish are fed exact percentages of their weight etc. after periodic weights are taken of the fish. Sorry I don't buy it for general application.

My guess is conversion is really in the 2 range.
Great sales pitch though.
