I have a friend who was first a navy diver , then worked offshore , then worked for the gov checking bridge pilings on the Miss River. He also would wrestle 100lb cats up from the oxbows. He said matter of factly he often saw large shadows (car size) swimming around when in the Miss river. I have seen film of very large fish around the offshore rigs. heybud I don't know if they were jew fish but they were telling you the truth about fish that big.
