Escaped farmed salmon have a huge genetic impact on wild Atlantic salmon. Large genetic changes by hybridisation with farmed salmon are documented in 77 Norwegian salmon rivers (31% of populations). New report brage.nina.no/nina-xmlui/han… abstract in English NINAnature NINA naturforskning

Novel large-scale mapping highlights poor state of sea trout populations. Salmon lice from salmon farms had by far the largest adverse effect on sea trout. Agriculture and hydropower production also had strong adverse impacts doi.org/10.1002/aqc.40…

Can't wait to see you in Scotland 🏴󠁧󠁢󠁳󠁣󠁴󠁿

Thank you fsbi MASTS Scot Gov Marine SSE - A Better World of Energy for supporting us 🙌

Salmon lice from fish farms push sea trout towards a crisis. The impact on sea trout is so large that this threat alone has been and will be the determining factor for the development of sea trout in Norway.

The #NoWPaS2024 committee is delighted to announce that the next edition will take place from the 26th of February to the 1st of March 2024 in Cromarty, Scotland ! 🏴󠁧󠁢󠁳󠁣󠁴󠁿 More details will be provided in the coming days, so stay tuned ! 🐟 #phdstudent #postdoc #salmonids

Salmon, trout + char aficionados!

At 1/100th the size of a typical #anadromous salmon, here are perhaps the world's smallest mature female #Atlanticsalmon (9-11cm, 10-20g, 15-30 eggs). They eke out a living in low order streams of #CapeRace , #Newfoundland (no access to sea)

Are you a PhD or PostDoc studying salmonid biology? The NoWPaS Workshop is for you! Keep your eyes peeled and get your abstracts ready as the applications for the workshop will go live in the next couple of weeks and spaces are limited. Find out more here: nowpas.wordpress.com/upcoming-event…

Antall #pukkellaks tatt ut fra norske elver har nå passert 100 000! Det største uttaket var i Syltefjordelva mandag, med 7938 pukkellaks k ett notdrag(se video). Vesterelva har samlet sett det største antallet pukkellaks #pukkellaks meldinger Les mer: miljodirektoratet.no/aktuelt/datavi…

Thanks again to the fsbi for their grant, allowing me to present my work at the @fsbi2023. It was very exciting to meet other 'salmon people' working on the smolt and post smolt such as Emma Tyldesley and Domino = @[email protected] for her work with Paolo Moccetti 🐟 #FSBI2023 Ecobiop

Great to catch up with Domino = @[email protected] and learn that...

Genetic markers could be used to predict outmigration success

Traps are installed in more than 30 rivers in North Norway to stop alien pink salmon from entering the rivers. Overview of pink salmon caught will be updated at miljodirektoratet.no/aktuelt/datavi… (in Norwegian, all graphs show number of fish)

Atlantic salmon has an amazing growth potential in the ocean. We tagged salmon after spawning, weighing 3-10 kg. After a year in the ocean, these fish weighed 9-18 kg. One individual had put on 10.6 kg! Strøm et al. link.springer.com/article/10.100…
