Returning home after having a great time at #freeflowconference in #Groningen. Great talks and excellent networking opportunities. @RivEM_Karlstad @life_connects @Energi_mynd @fishmigration

Closing up the @MSCA_RIBES project with the final conference @PoliTOnews. Inspiring presentations by the ESR's, including @veli_stoilova @RivEM_Karlstad @NorconsultAS , & keynotes by @jorg_freyhof, Chris Katopodis and @Paul_Kemp_Fish. Thanks to Claudio Comoglio & @DaniNyqvist.

@JohanSvenningss Hör Johan Tielman berätta om fiskskruven som invigdes vid Emån idag, hur den transporterar fisk både uppströms och nedströms samtidigt som den utnyttjar vattnets energi för att generera elektricitet.

@JohanSvenningss Jag vill rikta ett stort tack till alla inblandade, säger @JohanSvenningss Fiskskruvsprojektet är ett resultat av samarbete och innovativt tänkande mellan forskare, näringsliv och myndigheter. @life_connects @LstSkane @KAU @LansstyrelsenVG

I'm happy to announce that a new @hy_peak paper is coming out soon! I just submitted the page proofs today. ✔️ Stay tuned to learn more about key questions to guide #hydropeaking research in the next years.

FISH IN TROUBLED WATERS – 20 giorni Il documentario teatrale nato dall'unione di @MSCA_RIBES e #FaberTeater andrà in scena 📅il 28 settembre, 18:30 📍nell'aula magna del @PoliTOnews Prenota ora il tuo posto: bit.ly/fish-in-troubl… #ingegneriaidraulica #Biologia

We are getting to see some passage solutions and ofcourse the lovely fish depending on it at the 5th @MSCA_RIBES Network School hosted by @RivEM_Karlstad #trout #salmon

I am part of a multidisciplinary research consortium and sometimes it is challenging to explain ideas to people not from your field. Finally I found a method to explain individual variation and the problems my research to my engineering colleagues. @MSCA_RIBES @Fiskmarknad

The final result…

Relocating the mother of all PIT-antennas to track sea #trout in the river #Nybroån with ESR Florian Eggers (Fiskevårdsteknik) and Anders Nilsson from @AquatEcology_LU @MSCA_RIBES @KAU

@PSF_GBFISHLAB @AquatEcology_LU @MSCA_RIBES @KAU Oregon (TI), the river is about 12 m, but we are struggling with the range…

@OlleCalles @AquatEcology_LU @MSCA_RIBES @KAU What company did you use for the PIT antenna? Length of the river reach you can cover?
