Status & Trends by Species

Chum


© E.R. Keeley

Chum is an anadromous fish species, and has been named as a focal species by subbasin planners in 11 subbasins. Status and trends data are available for this species in 3 subbasins. 8 subbasins have no data available. Chum is Federally protected in 11 subbasins. No biological objectives have been set for this focal species in the Columbia River Basin.

Chum usually spawn in their 3rd, 4th, or 5th year, entering freshwater later in the year than other salmon species. They usually spend minimal time in freshwater, generally only to reproduce. During their first spring of life, chum salmon migrate to estuaries to spend several months before entering the ocean.

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.
