new paper out today on fishway efficiency. What makes a fishway efficient? More importantly, can we all agree on the best methods to answer that question? #fishsci #fishways #fishpassage onlinelibrary.wiley.com/doi/10.1111/fa…

Freshwater fish move within the river to use different habitats for feeding, breeding and as refuge.

Salmon are very capable jumpers & swimmers but they also have major problems passing Annacotty weir. This ornamental weir delays their migration. They can suffer injuries & all waste valuable energy. Many do not make it upstream. Please sign the petition: my.uplift.ie/petitions/remo…

It's a beautiful day next to the #RiverSevern. Mark Yeldham and Jonathan Bolland are out placing acoustic receivers along the river ready for the #SevernShadRun #FollowTheShad Canal & River Trust Wales and South West Severn Rivers Trust Environment Agency Research @ Bournemouth University

Downloading our barbel movement and temperature data, couldn't ask for better weather ☀

I leave Severn Rivers Trust in a couple of months, I am asking on those who live, work or play on the Severn to kindly help raise funds for to help this mighty river and its wildlife. Please spread the word gofund.me/fd6e0865 Iolo Williams @DaveThroupEA Jack Perks

A little video update from the river bank at the end of a very busy first week of the #RiverSevern shad run! We'd love to hear any of your #ShadSpotting updates over the bank holiday weekend! Don't forget to tag us and use #SevernShadRun 🐟🐟🐟 #FollowTheShad

Had a great week tagging twaite shad on the Severn, and am excited to find out where they go and what they get up to across the next three years! #ShadSevern #SevernShadRun

On #MayDay let's celebrate the amazing #MayFish migration! This year's #SevernShadRun is even more special - shimmering #TwaiteShad can swim past Victorian weirs in Worcester for the 1st time in nearly 180 years! #FollowTheShad #RiverSevern Severn Rivers Trust unlockingthesevern.co.uk/2021/04/20/the…

Lovely to see the first run of Twaite shad last week on the Severn. These are a rare freshwater herring which really struggle with barriers to migration. Unlocking the Severn Severn Rivers Trust Nina Constable Media BBC Springwatch

Via the NEW Diglis fish pass, twaite shad can now swim past #Worcester on their #SevernShadRun for the first time in nearly 180yrs! 🎉🐟🎉 Please watch & share our video! #FollowTheShad #FishMigration Canal & River Trust Severn Rivers Trust Environment Agency Midlands The National Lottery Heritage Fund Midlands & East LIFE Programme

Well this is exciting, my very first article has been published! Check it out if you’re interested in tagging effects and how size of smolts influence outmigration estimates. Thank you for a great collaboration Knut Wiik Vollset Robert Lennox Erlend M.Hanssen and more.

Tagged sea lamprey struggling to pass weirs in the Severn during their upstream spawning migration. A typical fate for migratory fish in our fragmented river systems, often occurring out of sight (+out of mind?). Read the full story in our new paper here doi.org/10.1002/aqc.36…

A project ~5y in development but on site <6h to remove 1.3m high & 9m wide weir and >100y of river fragmentation. Opened ~11km to free #fishpassage & #geomorphology #WeirTodayGoneTomorrow #damremovaleurope #UAP Upper Aire Project @PeteTurnerEA wildtrout.org/wttblog/newfie…

Interested in a PhD in #REWILDING? We have 6 fully-funded PhD projects available at the REWILD research cluster at the University of Hull on #eDNA, public perceptions, environmental impacts etc. with F. Blake Morton @aBugBlog @HopkinsChar @BerndHaenfling Prof. Dan Parsons @LboroUniversity 🌏💧🛰🌊⚽️🏏⛳🏈 ...

Faced with barriers to migration, how do animals respond? We found that some sea lamprey stay put downstream of weirs, and others wander substantial distances. In our new paper we examine the patterns, causes and consequences of this variation doi.org/10.1111/fwb.13…

Delighted to spend yesterday with Environment Agency Midlands & University of Hull at #SevernHam tagging #TwaiteShad as part of Unlocking the Severn. Great to see the tangible benefit the project brings first hand as these beauties make their way upstream to spawn.
