DNA seeps into water from a dead silver carp on a barge. Asian carp DNA surveillance programs determine the presence of Asian carp by detecting the genetic material (DNA from shed cells in slime, feces, urine, etc.) in water samples to correlate DNA detection with the possible presence of invasive silver carp or bighead carp.
