London, March 19 : Scientists in the UK have developed robotic fish that would released into the sea for the first time to detect water pollution.
According to a report in the Telegraph, the carp-shaped robots will be let loose in the port of Gijon in northern Spain as part of a three-year research project.
If successful, the team hopes that the fish will used in rivers, lakes and seas across the world, including Britain, to detect pollution.
The life-like creatures, which will mimic the undulating movement of real fish, will be equipped with tiny chemical sensors to find the source of potentially hazardous pollutants in the water, such as leaks from vessels in the port or underwater pipelines.
