- •
We applied alarm cue across a river during an upstream migration of sea lamprey.
- •
Alarm cue alters sea lamprey movement speed and timing but not migratory direction.
- •
Timing of upstream movement was context specific, differing by release location.
- •
Nonfeeding sea lamprey appear to balance risk and reproductive opportunities.
