I've only seen one bigger, one of my friends caught it in the pond behind our barn. We thought all the Crappie had died years ago. We where fishing to catch perch for our trotlines when he caught a monster Crappie that was 18 5/8 inches long. We didnt have a scale. He caught it on a white road runner with a grub on it. After that we forgot all about perch and caught a few more big ones in the 14 to 15 inch range. It was quite a surprise to say the least.
