White sturgeon are commonly found in deep, soft bottomed areas of estuaries, where movements in the water column is dependent on salinity.Construction of dams for hydroelectric power production affects seasonal movement of white sturgeon in many river systems, with the Columbia River Basin being a large contributor to shifts in the distribution and movement. When ready to spawn, white sturgeon choose a variety of substrates dependent on the river system, spawning on gravel or rocky substrate in moderate to fast currents, with observed depths of 3–23 m (9.8–75.5 ft), and water velocities at the bottom on a range of 0.6-2.4 m/sec.White sturgeon are a resource to a variety of different social and economic groups around the world. Sturgeon like to lay their eggs in fast moving water, which spreads the eggs out. Several species provide caviar from eggs. Globally, sturgeon fisheries are of great value, primarily as a source for caviar, but also for flesh. In: Acipenser. 2011-12-25 14:32:27 2011-12-25 14:32:27. [Acipenser transmontanus summary page.

Their typical lifespan is 55 years for males and 70 to 100 years for females.Lake sturgeon are listed as a threatened species in Michigan.
