Interpretive Summary: The arctic region has experienced warming in recent years, resulting in less summertime sea ice cover and higher sea surface temperatures. In September 2007, the U.S. BASIS survey extended surface trawling into the Chukchi Sea in the Arctic. Juvenile chum salmon were collected at most stations. Genetic methods were applied to juvenile chum salmon collected in the Chukchi Sea and Bering Strait to determine their country of origin. Most of the juvenile chum salmon caught in the Bering Strait were from populations native to northeastern Russia and the majority of fish collected in the Chukchi Sea site were from populations native to northwestern Alaska. These juvenile chum salmon appear to follow the northward flow of water from the Bering Sea.

Technical Abstract: The arctic region has experienced warming in recent years, resulting in decreased summer sea ice cover and increased sea surface temperatures. In September 2007, the U.S. BASIS survey extended surface trawling into the Chukchi Sea. Juvenile (young-of-the-year) chum salmon were collected at most stations. Genetic methods using microsatellite and SNP loci were applied to identify the origin of a subset of juvenile chum salmon collected in the Chukchi Sea and Bering Strait. Most of the juvenile chum salmon caught in the Bering Strait were from populations of the Anadyr-Kanchalan river system of northeastern Russia and the majority of fish collected in the Chukchi Sea site were from populations of northwestern Alaska.
