Metagenomics of the Mucosal Microbiota of European Eels

European eels are an economically important and threatened species that are prone to rapid collapse in farm conditions. Using metagenomics, we show that the eel mucosal microbiota has specific features distinguishing it from the surrounding aquatic community. This is a first step in dissecting the resident microbiota of this critical barrier that may have implications for maintenance of healthy eel populations.
