Status & Trends by Species

Coho


© E.R. Keeley

Coho is an anadromous fish species, and has been named as a focal species by subbasin planners in 18 subbasins. Status and trends data are available for this species in 11 subbasins. 7 subbasins have no data available. Coho is Federally protected in 12 subbasins. No biological objectives have been set for this focal species in the Columbia River Basin.

Coho salmon enter freshwater in the fall, and utilze relatively small, low gradient streams for spawning and yearing. Young coho typically migrate to sea in the spring of their second year, and return to spawn as three-year olds.

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.
