Estimations of Riverine Distribution,
Abundance, and Biomass of Anguillid Eels in Japan and Taiwan Using
Environmental DNA Analysis
This study, entitled ‘Estimations of Riverine
Distribution, Abundance, and Biomass of Anguillid Eels in Japan and
Taiwan Using Environmental DNA Analysis’, is the first to demonstrate
the potential usefulness of eDNA analysis for estimating the spatial
distribution, abundance, and biomass of the tropical eel, Giant mottled
eels in rivers. We found that eDNA analysis has a greater sensitivity
for detecting A. marmorata than electrofishing, making it a powerful
tool for monitoring the spatial distribution of the species in rivers.
We further applied this method to basin-scale surveys to investigate
the riverine distribution of sympatric Japanese eels and Giant mottled
eels, and our findings indicated that eDNA analysis could reflect their
spatial distributions. (112 words)
