Cecil, got a return phone call from the man, although I wasn't around to get the call. He say's the perch were in the 3" to maybe 4" range, so, it may have only been 2" in 3 months.
Still he said 6" was good.
Bill, thanks for the response. A question. You mentioned 2-3 years to get to 8". How old would you guess the fish in my pic is? I have no idea, but (probably wrongly) thought it was this springs spawn. So, no, then?
Thanks Esshup. You can see by the pic why I was using a floating rapala last night instead of sinking lure.

I get tired of draggging half the pond bottom in with each cast.
The water is very clear. Hard also.
