Which consequence occurs to salmon returning to natal rivers solely navigating by their olfactory system?

💡 Explanation

Increased straying occurs because the salmon utilizes olfactory imprinting to identify their specific natal stream. Absence of the precise chemical signature triggers dispersion, therefore straying increases, rather than affecting arrival timing, parasites, or avian risk unrelated to the nose.
