I stocked an equal amount of CC and BC the summer of 2015 at 4" long (from Overton's). They were 7-8" inside of 2 months. I've recently taken some out to eat at 18 - 20". When they were smaller, I always saw them feeding with the forage fish (BG, RES, GSH, Minnows...), not so much any more. I've caught mostly CC so far. The BC seem a little more reluctant to bite for some reason. Also, I know for a fact that the BC have spawned...haven't seen any CC YOY yet.

...when in doubt...set the hook...
