Exciting new tool for marine conservation: environmental DNA

Fish and other aquatic animals shed DNA into the surrounding water. This means that seawater is filled with the DNA of the animals living there, and this is known as environmental DNA (eDNA). Scientists have used environmental DNA to study a range of animals, from earlier eDNA studies in 2008 (e.g. on the invasive American Bullfrog), …
