Abstract
19–22 May 2021 Kyoto, JapanA lot of rockfish in the genus Sebastes exhibit distinctive homing ability. They can return back to an original location after displacement of metres or even kilometres. The black rockfish S. cheni is a site-specific fish, and shows homing to their original habitat after displacement. Using highresolution acoustic telemetry, we monitored homing behavior of the eight rockfish. The results demonstrated that they spent their time around the release site, and during this period they moved in the upstream and/or downstream direction. Then they gradually returning to their familiar area, and finally showed directed movements to the original habitat
