I did notice that one of the big ones I caught on Sat had part of it's lungs/swim bladder coming into it's mouth. Much like when deep dropping in the ocean and pull up a sea bass from 100'. I've been easing the crappie up when fishing in 15+ feet of water just for this reason. Over the weekend I had maybe three floaters that were borderline 10" (depended on which eye I closed when measuring it) so I decided to keep them anyway.
