We need to take responsibility for the harm that we provide our environment as it affects negatively both us humans and the natural habitats of other species. The toxicity that these animals get due to increasing pollution everyday gets back to us when we take them as food. This is true more so aquatic life of fish and other water species. So detect how much we have spoilt the seas and waters for these aquatic animals, scientists have developed an interesting way, that of a fake fish making the survey.

One of the usual way through which scientists detect that water pollution has occurred is through noticing the migration of fish and shift in their population. The fake fish idea has been carried out by a British firm called BMT, which is creating many such robotic fish to detect the quality of water and the level of pollution. Also, for the same duty to be performed, professional divers cost more and these robotic fish would do the same task but at relatively a lower cost. These fake fish are being called SHOAL fish and are equivalent to the size of a tuna.

They are just as fish-like in their movement as any real ocean fish but will detect chemical leakage and other environmental hazards present inside the water. The experts sitting in their centers monitoring these robotic tunas would get an alert if they detect something. The response then would be to try to remove that source which causes the pollution. The experiment for this type of technology is being carried out near the coast of Spain.
