Perform a Genetic Assessment of Columbia River Fish Stocks

This project includes four objectives that address needs for distinguishing specific stocks, determining genetic diversity, stock specific run timing, and estimating stock composition to provide information for fisheries management and harvest.

Project Goal

This project includes four objectives that address needs for distinguishing specific stocks, determining genetic diversity, stock specific run timing, and estimating stock composition to provide information for fisheries management and harvest.

Impacts

This information may be used to shape fisheries to increase tribal harvest.

Background

Determination of genetically distinct populations is one of the main premises for conservation under the Endangered Species Act. Genetic markers are continually being developed to better characterize salmon populations. Once populations of salmon are included in a genetic baseline, these reference collections can be used to determine stock composition in fisheries with Genetic Stock Identification (GSI) methods. Estimating stock composition of harvested fish for management is a key component of the Pacific Salmon Treaty.

Project Tasks

  1. Discover and evaluate SNP markers in salmon and steelhead
  2. Expand and create genetic baselines for multiple species (chinook, steelhead, sockeye, and coho)
  3. Implement GSI programs for mainstem chinook fisheries
  4. GSI of fish passing Bonneville Dam (steelhead and chinook)

These four objectives address needs for distinguishing specific stocks, determining genetic diversity, stock specific run timing, and estimating stock composition to provide information for fisheries management and harvest.
