Lake Sturgeon (Acipenser fulvescens), also known as Rock Sturgeon, is a North American freshwater fish, one of about 25 species of sturgeon. These fish can be found in large river and lake systems mostly in the Mississippi River Basin, Hudson Bay and Great Lakes basins. They are easily recognized by their distinctive torpedo-like body shape and elongated, shovel-like snouts. These fish can grow to a relatively large size, with a maximum length of over 2 m (7 ft) long and weight of over 100 kg (220 lb). The average length is about 1 to 1.5 m (40-60 in) and weight is usually around 5 to 25 kg (11-55 lb). Lake Sturgeon are bottom feeders that search for food with the help of four sensory whiskers near the snout, called barbels. Despite their large size, Lake Sturgeon feed predominantly on such small organisms as clams, crawfish, leeches, small fish, and aquatic insects.
