Green Sturgeon is a resident fish species, and has been named as a focal species by subbasin planners in 1 subbasin. 1 subbasin has no data available. Green Sturgeon is not a Federally protected species, though it is listed as a "species of concern" in 1 subbasins. No biological objectives have been set for this focal species in the Columbia River Basin.

Very little is known about green sturgeon, as they spend most of their life in the ocean. Green sturgeon grow slowly, and reach a length of about 7 feet and a weight of approximately 350 pounds. 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.
