Acipenser fulvescens -- Lake Sturgeon

A baby lake sturgeon is small enough to be cradled in a child's hand. However, lake sturgeon can grow to over eight feet in length and weigh up to 800 pounds, and they can attain ages of up to 100 years old. Destruction of food sources, invasive species and dam construction along spawning rivers have led to lake sturgeon being listed as a statewide threatened species in Michigan.

Wisconsin has "probably the strongest and healthiest lake sturgeon population"in the U.S.
