Thanks for the info Rainman.

I am even more intrigued by the idea of introducing tilapia into my ponds next spring. I initially was only intersted in the muck reduction potential, but the added benifits of LMB food, weed control, etc. are pretty cool in their own right.

But, back to the muck, which started this avenue of research. Considering that the lionshare of the muck would have derived from dropped leaves from the tree's the line the ponds and very little would be from inorganic silt from runoff, etc. since there is little in the way of a watershed for either pond, would this, at least initially, indicate to you that my particular muck situation would potentially be a good candidate for seeing some reduction of muck over some years with the introduction of tilapia in significant numbers each spring? if so, what might be a good number of pounds per pond to stock from your experience? (7/10 acre and 4/10 acre)
