Wednesday I caught quite a few dinks off the bottom in 32 - 37' of water. Several appeared to have swollen up coming up from those depths and could not swim back down. I've caught crappie from these depths before (different lake) and never had this issue.

I used to have to manually 'burp' big catfish caught deep with a skinny PVC pipe slid down their throat to their stomach before releasing. Do folks do that for crappie? I stopped fishing for them deep as I felt bad (too small to keep) and fortunately found some shallower.
