Salmon and Steelhead Life History

Salmon and steelhead have complex life cycles that begin with adults spawning in natal streams, rivers or lakes. The age and seasonal timing of salmon life cycle transitions are determined by their genetic make-up and influenced by conditions in nature or the hatchery.

Research in the Environmental Physiology Program aims to:


Effects of thermal regimes
Forecasting life history trajectories
Improving smolt quality
Reducing hatchery production of minijacks
Straying in barged steelhead
