Thanks Ant & Tracy, you both mentioned that I should also stock RES along with CNBG, What is the reason for that?

A little background info... The pond is 40 yrs old about .5 ac has LMB, the larger ones being in the 10-12" range. Abundant BG in 6" range, don't know when either of them were stocked. And about 25 CC that I stocked last spring. I also stocked 8lbs of Tilapia last spring to see if they would clean up the pond a bit, didn't see much difference. Initially they were growing and spawning like crazy, and I could see areas in the shallows that were cleaned down to the sandy bottom, but by late summer, they were harder to spot. I did have a 6-7' gator take up residence in summer along with 3 - 3' juveniles. Wonder if they cleaned out my tilapia?

I have 3 boys that like fishing, and can catch BG left n right, but the BG we have don't seem to get much bigger than 6" thats why Im thinking CNBG. To see if we can grow'em bigger for the dinner table.
