Jim Kerr, an aquatic scientist at Seastar Survey, presented results from experimental research he has undertaken to assess the upstream movements of European eel (Anguilla anguilla) and river lamprey (Lampetra fluviatilis) over an experimental Crump weir at the 'Fish Passage 2015' conference in Groningen, Netherlands. The work focussed on the effectiveness of a unique new configuration of a bristle pass for improving the upstream passage of these species at barriers. The vertically-oriented bristle passes are attached directly to the walls of small gauging structures and facilitate the passage of both eel and lamprey over the weir by reducing flow velocity and providing a substrate for them to crawl through.

The 'Fish Passage 2015' conference was attended by over 500 delegates from around the world including leading academics, commercial enterprises and government representatives. Current best practise for upstream passage of a multiple species was discussed including empirical data collected from multiple field studies. 

Jim undertook his research at the International Centre for Ecohydraulics Research, University of Southampton, UK. He is looking forward to using the knowledge he has acquired to implement effective fish passage solutions at migration barriers throughout the UK.
