I am a Tilapia fan thx to ML and I have to confirm that I have seen a lot more BG since adding the Tilapia. I am only stocking when I have an FA problem and I was not sure if I had survival this year since it never got very cold, but the BG are still much better now than before and no FA problems. I stocked the Tilapia and no FA problems in three different stock tanks (ponds). My only problem is that I can't catch them, see them, hear them, or know if they are even still there. We throw cast nets but no Tilapia show up and I never see small fry along the banks. I will restock next year and think they have really helped.
