esshup you have given me an option with the Blue Tilapia for next spring. Since our ponds are nearly the same size, what size and how many Blue Tilapia do you put in, and how early in the spring are they available? Do you have a good source here in IN for them? I live 75 miles south of Ft. Wayne and will most likely have to drive beyond Ft. Wayne to get mine. I would transport them in a cooler rigged with an oxygen pump to back home.
Here is a vague map of where you may find Northern Redbelly Dace close to Indiana.
