Maybe I'm just naive, but it seems to me that a scientific study utilizing small ponds(1-3 acres) could be done to determine the effects of different forages on each other. There seems to be no arguement that TFS, GShad, & GSH usually have a positive effect on LMB growth, so the question here is how much if any negative effects do they have on BG. Can't this be determined over a say, 3 year period by stocking BG and LMB in one pond, BG, GSH, LMB in another, BG, TFS and LMB in another, BG, GShad, and LMB in another. The ponds would treated all the same, ie:no feeding, no fertilizing, just mimic what happens in nature. It looks like to me from reading these posts that this question hasn't been answered, but there are lots of different opinions..du
