The use of eDNA in aquatic sediment has been useful, but can even be applied to open water for present day study.[1] Before eDNA, the main ways to study open water diversity was to use fishing and trapping, which requires funding and skilled labour, and other various resources, but eDNA only needs samples of water.[7] This method is effective as pH of the water does not affect the DNA as much as previously thought, and can be made more sensitive with relative ease.[7][12] Sensitivity is how likely the DNA marker will be present in the sampled water, and can be increased simply by taking more samples, having bigger samples, and increasing PCR.[12] eDNA degrades relatively fast in the water column, which is very beneficial in short term conservation studies such as identifying what species are present.[3]
