In France, a scientist put electrodes and a radio transmitter into a trout's brain. A computer reads and decodes the signals. The trout reacts strongly to tiny amounts of pollution in its water. The fish can detect as little as one-billionth of one gram of a pesticide in a liter of water. More trout like this one can be used as pollution meters. All you would have to do is let them swim in questionable water, and tell us what they think about it.
