Notes
1) Ocean age 3 abundance
2) Elwha, Dungeness, Area 9A, and Area 12A mgt. unit hatchery forecast values in this table include natural production origin
coho forecasts for these units, due to co-manager agreement on "secondary" mgt. status of natural coho production in these
units. FRAM model uses discrete inputs for the individual hatchery and wild origin forecasts.
The separate OA3 natural forecast values are: Elwha R.= 969, Dungeness R.= 1156, mgt. unit 9A = 162, mgt. unit 12A = 456
3) Columbia Oregon Wild are considered to have intermediate return timing relative to the early and late population groups
and are therefore categorized separately in this table.
4) 2008 is the first year Columbia River wild coho forecasts are being directly used in FRAM management model
due to inclusion of new FRAM Model base years with Columbia wild coho stocks.
