The Project will use otolith chemistry and microstructure to monitor how salmon use the Delta as rearing habitat and a migratory corridor, and the mechanisms cuing their outmigration from natal rivers. The Project will explore the extent to which delta rearing contributes to salmon population resiliency under different conditions (including drought) and provide baseline date to assess population responses to furture habitat restoration and climate change. Otolith reconstructions will be used to investigate the populations and life history types using the Delta, their duration of Delta-residence, and the relative growth rates by habitat, population and phenotype. The Project will generate empirical data tha will inform management aiming to maximize salmon abundance and life history diversity in order to buffer against future stressors.

Objectives are to determine the natal contributions to out-migrating juvenile salmon, Delta habitat use of out-migrating juvenile salmon and mechanisms governing juvenile salmon out-migrating timing from natal rivers.
