Detecting Mekong giant catfish using environmental DNA

Nice approach
As fish don't leave trails such as footprints or excrements fit for recognition, such as mammals do, knowing whether a very rare species is around is obviously hard. This technique might solve that problem - and in fact, it could result in an ending of sampling - just fetch water, analyze it for the known species and the trick is done.
