EDNA(environmental DNA) is DNA that is found in samples from an environment like say water samples or soil samples but without first isolating any target organisms. using eDNA in trying to track fish in a river would be very hard if not impossible because you have not found the initial target you only got samples from water or soil.
hope this helps if not just let me know
