George, I suspect that you are right about the bass eating all of the tilapia fry. I have seen some young tilapia in warmer months but not nearly as many as I was seeming when I stocked the bass fingerlings. Those bass are 14/15 inches now and they have spawned twice so I may be getting overstocked with bass. I do see a lot of fingerling and one year old bass. I am going to resort to chemical and mechanical control of the FA this fall and maybe get ahead of it next spring. Thanks for your comments.
