DNR ichthyologist John Lyons gives a hands-on lesson about the shovelnose sturgeon, which is little-changed from ancestors that lived millions of years ago when dinosaurs roamed what is now Wisconsin. The species is well-suited for life in the deepest and fastest parts of the state's largest free-flowing rivers. But an increasing demand for caviar could put the shovelnose sturgeon at risk from illegal fishing.
