White Sturgeon

White Sturgeon (Acipenser transmontanus) are the largest of all North American freshwater fish.

White sturgeon have changed little over the past 400 million years. Historically, white sturgeon populations existed throughout the West Coast of North America from the Aleutian Islands to central California. White sturgeon populations have decreased in the Columbia River over the last century.

Regional federal, state, and county agencies have expressed growing concern over the fate of white sturgeon within the Columbia River. This has prompted public utility districts to initiate studies focused on white sturgeon research and enhancement. These projects have led to the supplementation of juvenile white sturgeon into Mid-Columbia Reservoirs. Columbia Research is a leader of field research involving the capture and analysis of white sturgeon. Our work includes capturing, analyzing, and tagging juvenile and adult white sturgeon to determine size, age structure, survival rates, abundance, density, conditions, and growth rates. We also identify distribution and habitat selection.
