The largest crappie I have ever caught was 15.5 inches. I have no idea what he weighted but I guess a little over 2lbs. I have only seen one crappie over over 3lbs in my life. My dad and friend caught him a trotline back in the early 70's. We had a old wooden boat that leaked like sieve. They checked the lines while my job was to bail water with a old Folgers coffee can. I was 9 years old and we ate that fish the same night we caught him. No one was interested in records back then.
