• Description:
  Here we assess stock specific differences in stable isotopes and measures of nutritional condition (lipid and protein) in chum salmon (O. keta) collected from the North Pacific during the 2022 International Year of the Salmon Pan Pacific Winter Survey. We discuss the importance of incorporating genetic stock identification, life history stage and growth when applying biochemical measures to understanding trophic processes from winter months in high latitude systems.
