摘要

Populations of most freshwater mussels (Unionidae) are declining worldwide; these includes Sinanodonta spp., which inhabit artificial ponds in Japan. The detection of environmental DNA (eDNA) would be a rapid and efficient method for monitoring the distribution of Sinanodonta populations. Accordingly, the aim of the present study was to compare the results of real-time PCR-based eDNA detection to those of hand collection in 24 ponds in Japan. Sinanodonta eDNA was detected in most of the study ponds where Sinanodonta spp. were found by hand collection, and there was a positive correlation between the eDNA detection rate and the number of Sinanodonta specimens collected by hand. These findings demonstrate that eDNA detection is a valuable alternative method of evaluating the distribution of Sinanodonta spp., and that this method has a similar detection sensitivity to that of hand collection. The eDNA method can be used to monitor freshwater mussels at broad scales and prohibitive depths where hand collection is difficult.
