20. European Eel monitoring

Aim: Improve wildlife corridors

Water body: River Ash
Project description

Elver monitoring on the Ash as part of a wider monitoring programme through the Thames catchment.

Over the past 30 years it has become apparent that European Eel (Anguilla anguilla) recruitment into European rivers has declined rapidly. In 2005, ZSL set up its European eel monitoring programme to assess the presence of migrating juvenile eels, identify restrictions to their movements and gather long term data on trends in eel recruitment in the Thames catchment.

The eel pass and trap on the Ash was installed in May and members of the Spelthorne Natural History Society have been doing sterling work monitoring the trap since. Monitoring will stop at the end of September and a report on this year’s data will be available from late October.

ZSL are always on the look out for more Eel volunteers! Please click on the project contact link below to find out more.
