Animating fish movements

​

Client: Unlocking the Severn

 

Five fish species in the River Severn were tagged with acoustic tags and then tracked with remote receivers across a period of five years. During this time a huge restoration project has been underway to remove or alter barriers to movement.

​

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

​

The data were 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).

​

Select the species of fish you want to look at, the environmental conditions and before or after Powick weir was altered then press play. If you'd like to see another variation of fish species or 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.
