200754500 - Stock specific run timing and upstream migration mortality of adult Chinook salmon and steelhead through genetic stock identification and PIT tagging at Bonneville Dam

Sponsor: Columbia River Inter-Tribal Fish Commission

Short description: This project seeks to use Genetic Stock Identification (GSI)and Passive Integrated Transponder (PIT) tags to better assess Chinook salmon and steelhead adult migratory timing and survival through the Columbia River hydrosystem.

Location: Mainstem/Systemwide province, Systemwide subbasin

Budgets: FY08: $101,534 | FY09: $21,616

Primary species:
Anadromous: Chinook: All Populations
Anadromous: Steelhead: All Populations


ObjectiveDescriptionSubbasin planStrategies
1. Run timing of Chinook and steelhead stocks. This objective is intended to determine the peak timing of ESA listed and non-listed stocks to best manage harvest periods. Fisheries can be shifted to target healthy stocks and avoid those at risk to extinction. (None) Mainstem amendment strategies: -Protect biological, life history, and stock diversity -Prioritize mainstem protection of salmon and steelhead and support stocks that significantly contribute to harvest while having little impact on native/wild stocks.
2. Estimate stock upstream mortality and straying The combination of GSI information (stock proportions) and PIT tag detection will allow us to estimate mortality and stray rates of Chinook salmon and steelhead as they migrate through the hydrosystem. (None) Mainstem Amendment Strategies: -Emphasize adult survival as high priority. -Research aimed at optimizing fish and wildlife benefits and energy production.
