White sturgeon are the largest freshwater fish in North America and can weigh over 1,500 pounds, be 20 feet in length, and live for over 100 years. It is characterized by its large body size, large head and mouth, and long cylindrical body. It has four barbels located in front of its large, wide and toothless mouth, located on the bottom (ventral) side of its head. It has no scales, but "scutes" along its body for protection.
The white sturgeon is a slow growing, late maturing anadromous fish. White sturgeon spawn in large rivers in the spring and summer months and remain in fresh water while young. Young white sturgeon primarily feed on algae and aquatic insects while remaining in rivers and estuarine environments. White sturgeon primarily feed on fish, shellfish, crayfish, and on various aquatic invertebrates, clams, amphipods, and shrimp.
