Esox Lucius, 118 cm 12 kg, for you weird ppl not familiar with SI units, it’s 46.5 inches and 26.5 lbs. What a beauty.

"Der er ikke penge til at måle efter pesticider i grundvandet i år" Det lyder som en dårlig joke 😱 #dkgreen www.altinget.dk/miljoe/artik...

Is there something at the end of the rainbow?

We are at it again. #ABFT

We’re deploying 106 receivers in the inner Oslofjord for the NMBU cod project with @oceantracking.bsky.social. This study tracks migration and movement shifts in two cod ecotypes and assessing habitat changes. Using Thelma and Innovation equipment, an open protocol is key to the project!

Modtog i 2022 Ebbe Kløvedal Reichs Demokratistafet. Det er en interessant pris for ud over æren, får man den opgave at gøre noget for demokratiet. Jeg skrev bl.a. en lille bog. Den er nu tilgængelig online for den gavmilde pris af 0 kr. online.fliphtml5.com/gwgkt/dzpl/#...

Out in the LilleÅ river, to search for spawning grounds for trout, after their spawning season. The number of spawning grounds can help estimate the status of the population #salmotrutta #trout #seatrout @kimaarestrup.bsky.social

Just a nice little spawning ground you think. But in fact the first Sea trout to spawn here in 500+ years. And only because barrier at Mill pond further downstream was removed. #riverrestoration

Yesterday after work walking along local stream looking for this. Can you guess what it is? Hint, it’s not created by humans.

Christmas is spawning time for danish sea trout 🎄 #trout #seateout #spawning #salmotrutta @kimaarestrup.bsky.social @fishybiologistkim.bsky.social

After some delays caused by gas build-up in the chambers, we're finally off to the races! Always satisfying to see all the parts come together :) =[🐟]= =[🐟]= =[🐟]= =[🐟]=

Today we downloaded and serviced the acoustic receivers in the last (and smallest) of the three Danish Straits, completing the 2024 downloads. If you have acoustic tagged fish in the Baltic or North Sea and think they could have been detected, check the ETN database. @fishybiologistkim.bsky.social

Cold fieldwork in Danish chalk stream River Villestrup, trying to recapture adult Sea trout tagged with heart rate loggers. Gin clear water and thousands of Sea trout since dams and weirs were removed a decade ago. @mariepedaccini.bsky.social with a male and female. @fishybiologistkim.bsky.social

Yesterday we downloaded and serviced the acoustic Thelma receiver array in The Sound (Øresund) between Denmark and Sweden. Data will be uploaded into the European tracking network database.

Tagging sharks today with acoustic transmitters. Today’s species is Spiny Dogfish. Excited to follow their migration over the next three years with European Tracking Network. @aquatictracking.bsky.social @fishybiologistkim.bsky.social #NorTrack #DtoTrack

The Tagliamento River in Italy is under threat from flood protection measures. Please sign this petition if you oppose these actions: docs.google.com/forms/d/e/1F...

The Turnu Măgurele-Nikopol hydropower project on the Lower Danube has been added to the EU's priority investment list, despite the fact it will increase flood risk, threaten protected areas and the survival of critically endangered species, and violate the EU's own policies. Read more:

Atlantic Bluefin Tuna tagging has started. Tagging with multiple tags.This 282 cm absolute beauty got both a PSAT & an acoustic tag. #ScandinavianBluefinMarathon

Tagging these beauties again this year (Picture by Bettina Pedersen). Stay tuned.

Last week's news❗❗ It is maintenance time, we downloaded the 26 #ThelmaBiotel receivers composing our high-precision array located in Cíes Island🏝️ This array is set to detect #OpenProtocol (OP) acoustic transmitters🔎 I cannot wait to see what the fishes have been up to👀🦈 #TrackingNotSlacking

⚠️⚠️ Innovasea has moved to encrypt their coding schemes to ensure that their tags can only be detected by their receivers. Imagine if Apple decided that iPhone users could only call other iPhone users? You could no longer call your friend who owns an Android. Important thread 👇

Very important Update for acoustic telemetry users.
