They did tag and return this one to the wild. Best thing for an old one like this. He's lived this long, let him live some more.
I watched one about this size or larger on the River Chute where we fish 2 years ago. He had come to the top out in the middle. I thought is was an alligator but something was not quite right. I eased over and he had about a 1lb and half crappie in his mouth. He swam to the bank to get his feet underneath him to eat his catch. That is their method of catching and eating a big fish.
