esshup,
I was wrong about Swingle's treatment of the BG in the LMB-BG combinations. He stocked the BG in December which was the same time he stocked FHM. So the BG probably grew substantially by May when he stocked the LMB. The total weights of "BG only" were 166 lbs/acre while the "LMB-BG only" were 251 lbs/acre. The growing period for BG in the "LMB-BG only" ponds were a full year but only 6 months in the "BG only" ponds. The FHM would have began spawning in March which in part explains why they increased production to a greater extent than GAMs. GAMs have potential to greatly reproduce in the hot months when FHM stop spawning down South at least. So they are good in combination down here I think.
