Researchers at the Technical University of Madrid (UPM) in Spain and the University of Florence in Italy are developing an autonomous underwater vehicle equipped with biosensors to monitor water quality.

The robot, which mimics a swimming fish in order to minimize the disturbance to the natural ecosystem, can detect in-situ real-time anomalies to control environmental conditions in fish farms. In addition, the robotic fish can modify the way it swims according to the water conditions that, for example, can enable it to detect and highlight the areas of concentration.

Since water acidity directly affects other indicators of both water quality and fish health, the researchers also developed a special electrochemical pH sensor.

"Thanks to this system that provides early information on environmental change, we can control the parameters of water quality and improve management decisions of fish farms and, consequently, the wellness of these animals," says UPM's Claudio Rossi.
