Challenge of monitoring cohesive movement in homing fish using fine-scale 3D positioning Open
Rockfish, which are well known for their site fidelity and homing ability, live sympatrically with many conspecifics. Conspecifics may be external drivers influencing rockfish movement, and rockfish may move cohesively while travelling. We…
