Scientists have created a robot fish that fights amphibian exterminators
Australian scientists have created a robot fish that protects amphibians from the attack of eaters of small fish and tadpoles. The study was published in the scientific journal Cell.
Experts have created a robotic fish that attacks Holbrook mosquitoes (Gambusia holbrooki), which prey on amphibians. Thus, scientists artificially reduce the activity of aggressive fish, without causing them physical harm.
Scientists noted that gambrusia were bred in bodies of water around the world to control mosquito larvae, thereby containing the spread of disease. However, later the fish settled down and began to exterminate not only mosquito larvae, but also attack local freshwater fish and tadpoles. Researchers at the University of Western Australia noted that the Holbrook mosquito population should be reduced for the sake of ecology.
As part of the study, a robotic fish was created that resembled a largemouth bass (Micropterus salmoides) in appearance and behavior. Scientists have caught several mosquito fish and tadpoles and placed them in the aquarium along with the robot. When the fish tried to eat the amphibians, the robot simulated an attack and drove them away from the victims.
The experiment lasted for several weeks and ended successfully. Gambusia began to attack tadpoles less often, reduced weight and significantly reduced fertility. Their males are faster to avoid robot attacks more effectively, but less aggressive. Scientists stressed that after success in the laboratory, the experiment can be repeated in the wild.
