Ewest, I'm keeping every one that I catch (well 'cept for the 4 biggest ones - I know they were there, because I handled all 4 when the pond was renovated). I caught one of them this Spring on a 5" floating Rapala. It was fun getting the 25" 14.5# CC in on 4# test line! After weighing and measuring, I slipped one of Gregs' numbered floy tags in it. So far I haven't seen it, nor it's 3 other rather largish buddies.
The ones that were stocked Spring 2009 all had the adiopse fin clipped off. I'm trying to get a handle on the growth rates.
