University of Saskatchewan researchers discovered that wild fish release chemicals called ‘disturbance cues’ to signal to other fish about nearby dangers, such as predators.
The findings may have implications for fish conservation efforts across the globe.
“Disturbance cues may help to explain why some fish populations crash after they decline past a certain point,” said Kevin Bairos-Novak, a graduate student member of the research team.
While researchers have been aware for 30 years that fish release chemicals into the water, this is the first time their use has been studied.
