An Improved Genomics Tool for Characterizing Life History Diversity and Promotinf Resilience in Central Valley Chinook Salmon

Description / purpose

This study will improve our ability to protect the diversity of traits in Chinook salmon. The diversity of Chinook salmon migration timing is decreasing in the Central Valley. A key roadblock to protecting diversity is the current inability to rapidly and inexpensively identify large numbers of individuals from different populations during their migration to the ocean. This study addresses this information gap by leveraging pre-existing genomic data to develop a new technique that will allow scientists to identify individuals to life history type and location. For example, this study will potentially be able to identify Fall Run Chinook that are from the Sacramento versus the San Joaquin River basins. This information, in combination with data on water temperature and river flows, can determine the relationship between environmental conditions and juvenile salmon life history diversity. The information generated by this work will provide managers with the ability to accurately monitor the effect of key management actions on the different Central Valley Chinook salmon populations.
