2014 Annual Report: Genetic Assessment of Columbia River Stocks


This project combines four inter-related studies from the Accords Agreement that address the following current and future objectives: i) discover and evaluate SNP markers in salmon and steelhead and other anadromous fishes, ii) expand and create genetic baselines for multiple species including Chinook salmon (Oncorhynchus tshawytscha), steelhead (O. mykiss), Sockeye salmon and kokanee (O. nerka), and Coho salmon (O. kisutch), iii) implement Genetic Stock Identification (GSI) programs for mainstem Chinook salmon, Sockeye salmon, and steelhead fisheries, and iv) use GSI to estimate stock composition of fish passage at Bonneville Dam (steelhead, Sockeye salmon, and Chinook salmon) and juvenile Pacific lamprey passage at Lower Granite Dam. These four projects are highly related since Single Nucleotide Polymorphism (SNP) markers are needed to complete species-specific baselines, and these baselines are requisite to complete GSI. The results of these four objectives address needs for distinguishing specific stocks, determining genetic diversity, stock specific run timing, and estimating stock composition which can provide information for fisheries management.
