I was watching the History Channel last night and the had a show called MonsterQuest. The episode was called "Jaws in Illinois". It was a full hour about Bull Sharks in fresh water and they had pictures, but no video, of a 6 foot Bull Shark that was caught in the Mississippi by Alton, Illinois which is about 20 miles north of St. Louis and 600 miles from the Gulf. I think they said that Bulls have been found a couple of thousand miles up the Amazon. Given that, they could be in awful lot of water as far north as Missouri. Has anyone know or heard of anybody at all who has ever caught one? I guess one this size would be about impossible to land. They have to be really strong swimmers and one that is several hundred pounds would be about impossible to turn. FYI, I have caught several mulletts in the Meramec in 2000, which also can also swim up fresh water.
