ODFW's Kara Anlauf-Dunn conducted lab-based respirometry experiments at three different temperatures to obtain metabolic data (e.g., standard and maximum metabolic rate) on different stocks of hatchery spring Chinook salmon.
Climate forecasts and projected changes in stream temperatures may influence the distribution and persistence of native fish species. Understanding variation in thermal tolerance for hatchery spring Chinook salmon will aid managers of native species by helping identify species or populations most vulnerable to change.
These metabolic measures were then used to calculate aerobic capacity and functional thermal tolerance for each individual. This information will help make informed decisions about our fish populations and resources (e.g., set stricter fishing regulations outside of optimal thermal ranges for species, determine best species and stocks for reintroduction or stocking programs).
