ML :
You have the most important scientific facts that matter. Actual results on your ponds.
Bob and ML:
Thanks from me for an outstanding topic. Between ML's and Bob's posts yall have provided and outstanding short course on pond fish management even if that was not the intended result. I SUGGEST THAT READERS VIEW THIS THREAD IN THE BIGGER PICTURE AND NOT JUST ABOUT TILAPIA AS A PREY SOURCE.You have covered the mgt. and balance of fish in the pond from stocking to death (removal). Their are hundreds if not thousands of studies as well as textbooks that scientifically show/prove these concepts with all types of fish. I will check to see if I can find exactly what you are looking for.
There is little doubt that what has been described will work well if balance is kept , that is the key. The right # and sizes of the right type (prey & predator [not talking about BG vs. tilapia or LMB vs. CC or HSB]) fish for the carrying capacity of a given pond. Throw in good water quality and watch the magic work.
