Adult Chinook Salmon undertake extensive and energetically costly migrations between food resources in the ocean and their freshwater spawning habitats, requiring them to adapt behavioral and physiological traits that allow them to successfully reach their spawning streams and reproduce. Such adaptations may be shaped by physical factors in the environment and individual- and population-specific biological characteristics. Chinook Salmon in North America are important resources for both United States and Canadian stakeholders, but relatively little is known about their freshwater migration patterns and energetic status in Southeast Alaska. This work is a collaboration between the University of Alaska Fairbanks and the Alaska Department of Fish and Game. Given threats from climate change and mining activities, the results of this project will be useful for fisheries researchers as a benchmark for understanding migration behaviors in these Chinook Salmon populations, and our work indicates that integration of measure of energetic status into population monitoring may be a useful tool for creating management practices targeted at facilitating successful migration behaviors and increasing or maintaining body condition for these fish.
