eDNA (environmental DNA) refers to the genetic material that is present in the environment, specifically in the form of shed cells, tissues, or organic matter from organisms. It is a non-invasive method used to detect and identify the presence of different organisms in a specific environment.
eDNA from fish can be found in various water sources such as rivers, lakes, streams, or oceans. It is usually present in the form of fish scales, mucus, excreta, or cells that are released into the water as fish move through it. These DNA fragments can persist in the water for variable periods, allowing scientists to collect water samples to detect and identify the fish species present in a particular area.
