Sharks in Wisconsin?

[Weston]

Lab technicians positively identified these two teeth as having come from a two-to-three year-old Bull Shark. However, it was a semi-classified document dated February 12, 2006 from the Wisconsin DNR that really set the wheels in motion.  On that date, ice-diving biologists captured a nearly comatose five-foot Bull Shark in Lake Pepin, a widening of the Mississippi River. They were responding to reports from several startled salvage divers of a sleeping, “shark-like fish” in the open cab of a pickup truck that had gone through the ice a few weeks earlier. The Wisconsin divers located the truck in approximately 18' of water with the shark still inside, apparently hiding from the swift current. But the cold water had slowed its respiration and metabolism so much that it was barely alive. After an examination, the fish was tagged with a radio location device and released back into the river (Wisconsin regulations do not allow the keeping or transport of live, non-game fish). Sadly, marine biologists doubt the fish will survive until summer without the needed quantity of minerals and trace elements found in saltwater.
