LWJ I have looked at both the study and charts. This is the only thing I think you should take from the study. "Based on the results of this study, it seems feasible to maintain tilapia/bass ratios for one production cycle in a temperate climate."

I do not think you should base your decision on the aquaculture tilapia studies unless you want to run one for food production of tilapia and the sale of small LMB for stocking elsewhere. They are not dealing with recreational fish ponds with on going fish populations longer than 6 mths nor with over wintering tilapia. The biology of your situation (on going fish populations) is completely different than the studies. If the study ponds contained either over wintering tilapia or were not harvested out in 6 mths I am fairly sure they would have a big mess by the following summer.
