2014-2015 Michigan’s Living Resources patch, featuring the threatened lake sturgeon, now available!
Lake sturgeon (Acipenser fulvescens) are a unique fish species found in Michigan. These fish primarily inhabit large river and lake systems in the Mississippi River, Hudson Bay and Great Lakes basins. An important biological component of the Great Lakes fish community, lake sturgeon are listed as a threatened species in Michigan and as either threatened or endangered by 19 of the 20 states within their original range in the U.S.
Lake sturgeon, the only sturgeon species common to the Great Lakes basin, are the largest freshwater fish native to that system. Lake sturgeon can be considered a near-shore, warm-water species preferring water temperatures in the range of mid-50 to low-70 degrees Fahrenheit and depths 15 to 30 feet (although sturgeon in the Great Lakes are often found at greater depths). Lake sturgeon are benthivores, which means they feed on small invertebrates such as insect larvae, crayfish, snails, clams and leeches they find along the bottom of lakes and rivers. Read more
