Weissguy, a good example of tilapia as the only forage would be many of the lakes in Mexico. I have fished Lake El Salto, and with the year long growing season, Florida bass, and no danger of the tilapia getting too cold, the results are a great trophy largemouth bass lake. However, commercial fisherman net a quota of tilapia out of it every year to keep the numbers in order. I have been told that without the commercial removal of tilapia the bass fishing would be much different.
If tilapia were the only source, it would have to be in a region that you felt confident they would not die from the cold. Maybe in the butter zone where they dont die but also dont reproduce, for say 3 months a year. That would give the bass time to catch up with overpopulation of tilapia. I dont know if such a place exists?
