Fishing for effective conservation: context and biotic variation are keys to understanding the survival of pacific salmon after catch-and-release
Acute stressors are commonly experienced by wild animals but their effects on fitness rarely are studied in the natural environment. Billions of fish are captured and released annually around the globe across all fishing sectors (e.g., recreational, commercial, subsistence). Whatever the motivation,...

Acute stressors are commonly experienced by wild animals but their effects on fitness rarely are studied in the natural environment.
