Bill, I have checked stomach contents. Of course found pellets, small bass, small CC but no Crappies. I am not sure how well they have spawned. I add Crappies each year to try and help them out and this spring saw more on beds then any year previously but waiting to catch small ones in the winter through the ice. I catch several in spring and could not ask for them to look better. Very thick for Crappies. I have as yet not kept one but probably should to see what they are eating. I suspect they are helping with somewhat control of LMB. That's a good thing. It's a 10 A. rock quarry 22 to 35 foot deep and when we rented it 10 years ago it was full of stunted LMB. They are much better know.
