Lake Sturgeon

Lake Sturgeon

Acipenser fulvescens

Unlike most fish, the body of the lake sturgeon is not covered with scales. Instead, there are five rows of large, bony plates on the top and sides of the body.

The lake sturgeon lives on the bottom of lakes and large rivers. It prefers shallow waters, where it moves slowly over sand, mud, and gravel, looking for food. The sturgeon’s small, toothless mouth is located on the underside of its head. In front of the mouth are four whiskers, or barbels. Around the outside of the mouth are taste buds. The whiskers and taste buds are used to locate food. When a sturgeon finds something tasty, it puckers its mouth and sucks in the food.

Lake sturgeons mate and spawn (lay eggs) in May and June. The eggs are sticky, and adhere to rocks and other solid objects underwater. The eggs hatch about a week after they are laid.

Lake sturgeons have a long life span. They can live to be 75 years of age or even older. But old, large lake sturgeons are very rare. Lake-sturgeon populations have been greatly reduced throughout most of the species’s range. Overfishing has been a major problem. People kill lake sturgeons for their meat and for their eggs, which are salted and called caviar. People have caught lake sturgeons faster than the species can reproduce itself. Dams and water pollution have also killed many of these creatures.
