Eel surveys using eDNA on Jersey

BUG field staff have just come back from a trip to the Channel Islands, where they were undertaking surveys to assess the status of European eel (and other fish species) using a combination of electric fishing, fyke netting and eDNA.

A large European eel captured in a fyke net.

The purpose of the surveys was to establish a baseline of eel presence / absence and spatial distribution throughout the island, focusing on key reservoir and stream water bodies.

Environmental DNA, or eDNA, refers to genetic material collected from the environment in which an organism lives (including water), rather than from the organism itself. It has the advantage that presence/absence of a species can be determined without the need to physically capture (or observe) the animal.

Collection of eDNA is a relatively straightforward process, involving taking a water sample of known volume and passing it through a filter that will retain the sample of genetic material

Bournemouth University has comprehensive in-house expertise and genetic laboratory facilities, and can provide a complete package of eDNA assessment, from delivery of user-friendly sampling kits to production of comprehensive data reports.
