CONT

Philopatry (i.e., homing) to natal sites is a fundamental life-history trait of most anadromous salmon and trout. Homing increases the likelihood that reproductive-age fish will find mates and locate habitats that are favorable for both adult spawning and juvenile survival … Return to natal sites is therefore highly adaptive, providing fitness benefits and contributing to the evolution of thousands of locally-adapted populations …

OBS

Adult return [of fish] to natal site for reproduction; spatial scale can vary.
