Bruce -

The Vermont thing had me thrown, too, but T. mossambica can survive at
temp.s below 12 o C and the lake was deep. I assumed a fast growing fish
and maybe some warm springs as thermal refugia in winter.

I'd thought about that too, but I wasn't sure how big T. mossambica gets.
Living in a large, well-oxygenated lake with a healthy food web maybe they
get that big... and I have problems connecting Tilapia with Vermont, which
might not be a real problem.
