George,
So did you keep most of them to eat or where they critter snacks?
Also which pond are these in and what size is it, I am sure you have mentioned before so I apologize, also what other species are in the pond with the CNBG?
I feed them to the critters except for big ripe females and they go to my CNBG "intergrade" 1/4 acre pond - have some really nice fish there...
My best pure Florida CNBG are in main 2 acre pond with LMB and HSB.
Love big CNBG...
