Environmental DNA analysis refers to the technology that estimates the presence and absence as well as the biomass of organisms from DNA found in the environment. While it has only been 10 years since the birth of this technology, in freshwater areas one example of its utilization has been in the detection of alien species. A methodology utilizing environmental DNA for the assessment of marine biological diversity and biomass estimation has also been gaining recognition. Given the enormous power of environmental DNA analysis, there should be careful discussions on its appropriate use, giving due consideration to the conservation of the organisms that are its focus.
