Pacific herring ( Clupea pallasii ) are vital to the environment, economy, and culture of Alaska. Despite their importance, the genetic diversity and population structure of Pacific herring in western Alaska are not well understood. Using modern genomic techniques, we will conduct the first fine-scale genetic assessment of herring aggregations throughout the eastern Bering Sea. A large sample collection (>500 specimens) has been compiled by NOAA trawl surveys and NMFS fisheries observers, along with historical samples from spawning aggregations from the Alaska Department of Fish and Game. This variety of samples will allow us to assess the genetic composition of Pacific herring from numerous locations in the eastern Bering Sea. A combination of RADseq and low coverage whole genome libraries will be constructed, sequenced, and analyzed with bioinformatic tools. The genome of Atlantic herring will provide context and serve as a reference for our Pacific herring genomic analyses. SNP marker panels will be established throughout the Pacific herring genome, providing a foundation for future genetic monitoring. This project will provide valuable baseline genomic information on Pacific herring that will inform key decisions for the management of federal and state marine fisheries in the North Pacific.
