PROTIVIN, CZECH REPUBLIC — A Czech beer brewery has enlisted some curious creatures to help maintain the purity of their water supply. <br /> <br />Reuters reports that Protivin Brewery in the Czech Republic's South Bohemian region equipped crayfish with high-tech biosensors that monitor their heartbeat and movement. <br /> <br />The crayfish were placed in tanks, which were pumped with water from the same natural spring source the brewery uses to make its beers. <br /> <br />Crayfish are able to detect pollutants or impurities in the water, and react to it with changes in their body or behavior. <br /> <br />A computer analyzes the data and flags down changes in water quality when three or more crayfish change their pulse activity — with results coming in within 3 minutes. <br /> <br />Scientists at South Bohemia University have patented the water system, and plan to upgrade the technology to include a special crayfish-heart monitoring camera.
