200753700 - Population specific in-season forecasts of Columbia River Chinook salmon (Oncorhynchus tshawytscha) returns for allowing selective in-river fisheries

Sponsor: Columbia River Inter-Tribal Fish Commission

Short description: We will make accurate in-season forecasts of Columbia River Chinook salmon population-specific returns to increase the resolution of in-river harvest selection between weak wild and healthy wild or hatchery populations.

Location: Mainstem/Systemwide province, Columbia Gorge subbasin

Budgets: FY08: $66,508 | FY09: $33,254

Primary species:
Anadromous: Chinook: All Populations


ObjectiveDescriptionSubbasin planStrategies
1. In-river fishery selection The ultimate objective is to protect and recover weak wild Chinook salmon populations and increase in-river harvest of hatchery and healthy wild populations. Objective 1a: Provide population-specific forecasts of Chinook salmon runs on a real-time basis for helping in-river harvest decisions. Objective 1b: Improve accuracy of in-season forecasts. Objective 1c: Help managers to make harvest decisions by presenting a forecast outcome with its uncertainty measurement as well as point value. Columbia Gorge
2. Demonstration Test the forecast model that we develop. Columbia Gorge
