I have to thank Meadlark for putting the bug in my ear about the Tilapia. Has worked well on the Fil. Algae problem. Three tanks (or ponds) now look terrific. My question is , when do you see them? I saw a few the first month or so, but none since. The cast net brings up bluegill but no Tilapia. There are some fairly large bass but I can't see how they could get many of them this time of year. They are extremely fast and some were too large to be eaten at the time I put them in the water. By the way I also had problems with milfoil and that is no longer a big problem. There are carp in the tanks also , but they were they were there before I put in the Tilapia and did not control the milfoil. I can only guess the Tiplapia may be eating that also. I am rambling but just thought some might have some of the same questions and thoughts. Anyway, they are great. Now I hope they die off and feed my bass. Might not be so bad if a few survived and I did not have to buy them each year.
