Top left: Noble crayfish (Astacus astacus). Top right: Graph showing A) a comparison of the observed detection frequency (proportion of positive eDNA samples in a lake) between qPCR and ddPCR. The dotted line shows the 1:1 ratio. B) A comparison of the observed detection frequency between CPUE against ddPCR and qPCR. Bottom photos: eDNA sampling and trapping.
