p This robot fish is doing its part to make sure your seafood is contaminant-free.

A robotic fish could soon be patrolling the waters near you, used to monitor water quality by checking pH levels to make sure they fall within normal levels.

The polycarbonate and latex robot is the work of researchers from the Technical University of Madrid and the University of Florence.

They hope that it can be used in fish farms, where it will play a valuable role in keeping aquaculture systems at an optimal level.

“We designed a bio-inspired fish robot that is able to swim according to the directives sent in form of chemical messengers,” Giovanna Marrazza, an associate professor of Microbiology and Molecular Biology who worked on the project, told Digital Trends.

“The concentration of hydrogen ions in the environment is detected by an electrochemical multi-sensor platform.
