Homing Ability of Japanese Chum Salmon and Differences in their Return Timing by Reproductive Season

Abstract Excerpt:
To increase their harvest, the juveniles of chum salmon are stocked in several tributaries of river systems, and homing adults are captured from each tributary for hatchery broodstock. Therefore, it is important to understand the homing behavior of chum salmon for a successful management of their resources. In this study, I surveyed the homing ability of chum salmon and differences in their return timing by reproductive season.
