Here Come The Litmus Fish – indicator fish to turn color in response to pollutants – Brief Article

Using gene technology, scientists are developing a ‘rainbow’ range of fluorescent fish that could be used to detect waterborne pollution. Zhiyuan Gong, biology professor at the National University of Singapore has, according to The Financial Times, already produced a green-and-red zebra fish. He is presently developing genetically modified zebra fish in which the fluorescent colour genes are switched on by specific chemicals in the water, such as heavy metals. The ultimate goal would be an indicator fish that turned a particular colour in response to a particular pollutant.
