Just wrapped an incredible fieldwork week at Finse with @kwvollset.bsky.social 🎣 Fieldwork thread 🧵 (1/5)

PhD candidate Jessica Robichaud at Cooke lab at @carleton.ca is visiting us for a month to help with field work. Today, she presented her work for our lab. She is using acoustic telemetry to track permit in the Florida keys! So interesting to see some of her findings! 🐟

Tagging of Mustelus asterias

What a week it’s been! I’ve visited @lottepohl.bsky.social & David Casals at @vliz.be in Belgium for our #EMFish project. My first time seeing and tagging a Mustelus asterias - so cool! Thanks for a very fun day on the North Sea!

Pathogen and Gene Expression Profiles of Atlantic Salmon From an Endangered Population The role of pathogens in impacting the behaviour and fate of salmonids has been studied extensively for some selected pathogens such as sea lice. However, the whole pathobiome of the fish are seldom ...

New paper 🚨 Do pathogens predict salmon survival? In our recently published study on the Endangered Atlantic salmon, we combined acoustic telemetry with pathogen and gene expression profiles. Read the paper here

We’ve downloaded data from our receivers around Bergen city center for the #BOATS project. Interested to see an example of fine-scale positioning movement data from a tagged European lobster? Check out the BTN website here www.bergentelemetry.com/post/downloa...

We are now starting the second part of the #NFR_HITLICE project on Senja, Northern Norway, where we infect migrating salmon smolts with salmon lice and tag them with acoustic transmitters with predation sensors to investigate the vulnerability to predation 🐟

Beautiful day in field earlier this week deploying receivers in the fjords around Bergen city☀️ These will track some fascinating species that we’re going to tag through some new projects starting this year 🌊🦈🐠

Anchoring of the PIT antenna to the riverbed during low river discharge

Picture of the river Nidelva in Southern Norway with NORCE LFI employee snorkeling to make sure that the antenna is well secured and deployed

We've installed a PIT antenna in Nidelva to track returning Atlantic salmon smolts tagged last year through our #NFR_HITLice project. Smolts were infested with sea lice before release. Low discharge makes drilling the antenna to the riverbed easier, still a river with 3–4°C makes it quite tough!

Exciting news - we are tracking chimaeras, the ghost shark, in the Bergen city fjords We received great news from Save Our Seas Foundation that the Ghost Track project will be funded. The ghost shark, Chimaera monstrosa, is a deep water cartilaginous fish that occupies great depths. Th...

Manuscripts drafted and written, revisions done, application sent in, and we even had a GAM crash course - safe to say we can call the third year of writing retreat a success! ❄️

Paneled figure depicting a) the probability of a viral pathogen PRV detection in Atlantic salmon on salmon farms reaching nearly 100% the longer fish were on farm conditions b) the proportion of PRV positive chinook salmon in relation to distance to an active aquaculture site with PRV fish being more likely to detect closer to aquaculture and c) the global transmission of PRV from Norway and Iceland to British Columbia and Chile.

Recently out in Science Advances, we compiled and reviewed the evidence surrounding pathogens from salmon aquaculture and their risk to wild Pacific salmon in British Columbia. We highlight pathogen impacts in relation to climate change, evolution & management

Salmon are ‘coming home’ to spawn in Klamath River after dams are removed Years long fight by local tribes has paid off after four dams, which had blocked passage for fish for decades, came down

🪶 Less than a month after those dams have come down in the largest dam removal project in US history, salmon are once more returning to spawn in creeks that have been cut off to them for generations.Video shows that hundreds of salmon have made it to tributaries.
