• Description:
  Anadromous salmonids of the genera Oncorhynchus, Salmo and Salvelinus (hereafter, ‘salmon’), are culturally, economically and ecologically important fishes, affected by climate change at every life stage. Predictions about their future distribution and abundance are typically based on thresholds of thermal tolerance and changes to phenology in response to warming rivers, shifting flow regimes and complex marine processes (Crozier & Siegel, 2023). Numerous conservation efforts focus on mitigating climate change, mainly in spawning and rearing habitats via restoration efforts to increase population resilience and capacity. While habitat alterations may dominate the narrative for salmon in a climate-altered future, indirect effects of climate change will likely be nuanced and in combination with other human activities. One such process involves the straying of natural- (‘wild’) and hatchery-origin salmon through climate-driven changes in olfactory imprinting and detection of olfactory signals, and trade-offs between homing and spawning habitat selection (Figure 1).
