Consider salmon navigating to natal streams; which mechanism determines stream identity?

💡 Explanation

Olfactory imprinting occurs because juvenile salmon learn the unique chemical composition of their natal stream; therefore, adult salmon identify and return to that specific water source rather than choosing other streams because the unique 'smell' triggers homing.
