Which outcome occurs in salmon exposed to stream pollutants affecting olfactory chemoreception?

💡 Explanation

Disrupted homing migration occurs because stream pollutants impair olfactory chemoreception, diminishing sensing of natal stream odors for navigation. Therefore, they cannot return precisely, rather than enhanced perception, because crucial imprinting cues are absent.
