I guess I'll chime in on this. I have tilapia now for about 18 months. They survive the winter at my place so I have only done one stocking of 100 6-8".

What I have seen so far in the forage population. The BG have gone from a few large and medium ones to alot of small and medium ones in this time. Not much increase in larger size. Redears have come back with a vengance. I have gone from very few to hundreds weighing up to 1.5lbs.

Average LMB weight has increased .25-1lbs pending on length. I don't think that it is all directly related to tilapia but I'm sure that the indirect relationship is there.

On cold days like today, 25 degrees this morning, you can see hundreds of tilapia stacked in there where the warm well water runs in.
