Which navigational outcome influences salmon migration 'homing' using terrestrial chemical maps?

💡 Explanation

Salmon use olfactory imprinting; distinct watershed odors get memorized, because this learned detection guides them back home, therefore allowing accurate spawning site return, rather than relying on fixed internal magnetic or celestial directions alone.
