Robotic Fish Developed By Brit Scientists

British scientists have decided that they cannot spend time attaching tracking devices and cameras on fish, leaving instruments submerged in water or swimming around trying to collect. They have decided that the best information would be gained by the man-made fish population.
A robotic fish developed by the scientists will be released into the sea off the coast of North Spain. The 1.5 metre (5 feet) robotic fish is set to be left into rivers and lakes to detect hazardous pollutants in the water released from underwater pipelines. The robotic fish, which looks quite life like, can imitate the movements of fish and have chemical sensors which can detect pollutants. The information picked up by the fish would then be sent to the scientists via Wi-Fi technology.
The $29,000 robotic fish is extremely energy efficient, according to the team of scientists, and can travel underwater for hours on end. However, it is not yet know how the fish is being powered. Independently moving and not manipulated by remote, the robotic fish is undergoing testing and, if successful, more of these will be released into the Spanish waters.
