I am interested in using tagging technologies and remote sensing to investigate the movement ecology of marine and freshwater fauna, and how this can be altered by environmental changes and anthropogenic disturbance.
Tracking the movement and social behaviour of European eels in UK reservoirs
The European eel (Anguilla anguilla) is a critically endangered catadromous fish that spawns in the Sargasso Sea. As larvae, eels cross the Atlantic Ocean and reach the European continent, where many enter freshwater bodies, such as rivers and lakes, and mature before returning to the Sargasso Sea to breed. Modern water infrastructures, such as dams, reservoirs weirs, however, provide obstacles to the natural migration into, and out of, freshwater bodies in the UK and throughout much of the European eel’s range.
Reservoirs represent an interesting obstacle for eel conservation as they can provide excellent habitat for young eels to mature, and many UK reservoirs have large populations of eels. However, if eels naturally migrate or are pumped into a reservoir they are often stuck, with no potential outlet for migration back into our freshwater bodies and out to sea to complete their life cycle. Little is currently known about the movement patterns or social behaviour of adult eels in reservoirs, and a greater understanding of the movement and aggregating drivers in reservoirs is important to implement translocation programs to return maturing adult eels into freshwater bodies where they can migrate back out to sea to breed.
Working in conjunction with government bodies and water companies, this project aims to use high resolution acoustic telemetry systems and network analyses to investigate European eel moment around reservoirs, combined with abiotic datasets to develop predictive models to enable forecasting of eel movement and behaviour under a range of management scenarios, thus providing an evidence-driven tool to inform protection and passage strategies for this critically endangered species.
