See how fish move on the river

See how fish move up and down the river!

Across a period of five years, researchers working on the River Severn, tagged individual fish of five different species with acoustic tags and then tracked the movements of these fish on the river, using receivers along the river.

Here we display the movements of European barbel (Barbus barbus), pike (Esox lucius), zander (Sander lucioperca), sea lamprey (Petromyzon marinus L.) and twaite shad (Alosa fallax).

Select the species of fish you want to look at, specific environmental conditions, and drag to view a particular date or check the box to see data before or after our project altered Powick weir. Then press play. If you’d like to see a different species or vary the environmental parameters please pause the animation before changing your selections. You can also move around in the map to an area of interest or zoom out to seen an overview.

The data was collated from three PhD projects by Catherine Gutmann Roberts, Emma Nolan and Pete Davies, under the supervision of Robert Britton (Bournemouth University) and Jonathan Bolland (University of Hull).

This animation was produced with funding by the Digital Engagement Grant from the British Ecological Society.
