Robot Fish

Invasive mosquito fish are often fearless. Free from the predators of their native range, these mosquito fish run , throwing naive ecosystems from Europe to Australia out of whack. To keep the problematic fish in check, scientists are trying to fear back into the hearts of these swimmers with a high-tech tool: robots. In a laboratory experiment, a robotic fish designed to one of mosquito fish’s natural predators increased fear and stress responses in mosquito fish, impairing their survival and reproduction, researchers report December 16 in iScience. While robofish won't be deployed in the wild anytime soon, the research highlights that there are more creative ways of preventing behavior from a species than simply killing them, says Michael Culshaw-Maurer, an ecologist at the University of Arizona in Tucson who wasn't involved in the study. "It’s just wonderful seeing work in this area."
