Thanks for the link QA. Northern was my best guess based on other reading I had been doing, and that's what I come to from that chart to. They don't seem to be burrowing, so probably not a bad species to have around.
Bill, I will try to remember and get some close up pictures over the weekend. I sprayed the cattails this last week so there may be some FA die off from that, but otherwise I haven't treated them at all so it should give a decent idea of what the tilapia are managing. They went in the week of June 10th at about 1 inch long, so it may take a bit before they are of a good enough size to make a dent. I guess we will see on that part.
