A $29,595 robot is scanning Colorado River water for DNA left by invasive fish before they can spread into new habitats | - The Times of India
The Colorado River is getting a new line of defence against invasive species, with a $29,595 environmental DNA autosampler being used to search for traces of unwanted fish and other aquatic threats. Instead of waiting to catch an invasive animal, the machine collects water and looks for tiny pieces of biological material left behind by species moving through the river.
