Description
The aim of this study was to test whether the ichthyological diversity of one natural reserve in Reunion Island (Réserve de l'Etang de Saint-Paul) could be established with a molecular tool, environmental DNA (eDNA). We hence filtrated the water (2L) at 10 different areas around the reserve. For each sampling area, 12 PCR replicas were performed and the identification of fish species was carried out by metabarcoding through a primer over a mitochondrial region (12S). This study showed the importance of reference sequencing databases as well as improvements through phylogenetic analyses. This first fish study by eDNA in La Réunion also revealed the coherence of the distribution of species and their habitat.
