Fig 3. Probability of detecting bighead carp and silver carp eDNA during a monitoring event.

Fig 3

The probability of detecting the (a) bighead carp and (b) silver carp target marker is shown for monitoring events with 1, 2, 10, 20 and 30 water samples. At low concentrations in the environment, a large number of samples may be needed to detect the target marker with a high level of confidence.
