New eDNA technique can improve accuracy of tracking fish populations

A technique developed by researchers at Shanghai Ocean University could allow scientists to detect all species present in a body of water and their related populations, just by taking a mere water sample.

The team has developed a new approach to the use of environmental DNA, or eDNA, to estimate species abundance with less bias and variability, offering a more reliable tool for ecological monitoring and biodiversity protection.

Led by Li Chenhong, a professor at the university's College of Fisheries and Life Science, the research was published in the journal Molecular Ecology Resources on Feb 6.
