Researchers published the first experiments to gauge whether biomimetic robotic fish can induce fear-related changes in mosquitofish, aiming to discover whether the highly invasive species might be controlled without toxicants or trapping methods harmful to wildlife. Their findings indicate that even brief exposure to a robotic replica of the mosquitofish’s primary predator can provoke meaningful avoidance behaviors and physiological changes associated with the loss of energy reserves, potentially translating into lower rates of reproduction.
