Status & Trends by Species

White Sturgeon


Shedd Aquarium

White Sturgeon is a resident fish species, and has been named as a focal species by subbasin planners in 7 subbasins. Status and trends data are available for this species in 4 subbasins. Snapshot data are available in 2 subbasins. 1 subbasin has no data available. White Sturgeon is Federally protected in 1 subbasin. No biological objectives have been set for this focal species in the Columbia River Basin.

White sturgeon are the largest freshwater fish in North America, reaching a weight of approximately 1,500 pounds. They grow slowly, and may take up to 25 years to mature. Sturgeon skeletons are cartilaginous rather than bony.

Focal species represent the fish species that the subbasin planners have identified as focal species for the respective subbasin. The biological objectives associated with a focal species were either described in the subbasin plan or were included in state, tribal, or federal recovery/management plans. Biological objectives and current status are linked to their respective reference information; if the reference exists on-line, a link is provided to the original data.

The status and trend information represents the most current data that is available. Data were collected through interviews with biologists and reviews of reports and websites. Each chart is linked to a table of the data, and each datapoint in that table is linked to reference information. The focal species data presented have been reviewed and approved by the respective collectors.
