Happy World Lake Day! We post a lot of marine telemetry research, but did you know that a lot is done in lakes too?

New paper introducing the term of SUPER HABITAT for sharks in which all critical activities (resting, feeding, mating & giving birth) occurs. 🦈🌴❤️🍽️ 👶 Access the paper here: www.sciencedirect.com/science/arti... @dr-yannis.bsky.social @charlie-huveneers.bsky.social

Hello friends! The fieldwork and holiday season kept us a little quiet over here, but we’re back! Here's a meme (we hope you don’t relate to) until we get things going again 🐠

Come work with us! 2-year postdoc position open at SLU Aqua, on the role of herring in coastal food webs of the Baltic Sea. Applications due August 25. www.slu.se/om-slu/jobba...

What fish are you ?! 🐟🐡🐠🦈 Swipe to find out and let us know in the comments ! [Thread incoming]

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! @bergentelemetry.bsky.social @aquatictracking.bsky.social

Hello fishy friends! 🐠 We’re the team behind the scenes at the European Tracking Network — serving up deep science and even deeper puns 😈🐡 🎣 [Thread incoming] 🎣

Today is International Shark Day! Sharks are over 550 species that come in many shapes and sizes, from the minuscule 20 cm long dwarf lanternshark to the almost 100 times longer whale shark. Amazing! (but not a surprise, which was ruined by their names).

Have you used fish telemetry in your research? @cjfas.bsky.social is accepting submissions on how telemetry is being applied to support conservation and management in aquatic ecosystems. This includes work from @icft2025.bsky.social ▶️ buff.ly/Y2FTYRL

Satellite tracking reveals sex-specific differences in the geographical and vertical habitat use of Whale sharks, Rhincodon typus, in the Eastern Indian ocean 🦑🐟🦈 link.springer.com/article/10.1...

Happy International Angel Shark Day! 🦈 Angel sharks (Squatina spp.) are a group of 24 species found around the world. Adult sizes range from 95 cm to 2.5 meters, yet they can still remain completely invisible if you happen to cross their path. These flat-bodied sharks are masters of camouflage.

Last week, @mialybkaer.bsky.social, Ellen Jacobs, and I traveled to @vliz.be as part of the @dtobioflow.bsky.social project! We got into the nitty gritty to bring #porpoise pod 🔊 data to the #DataLake via @aquatictracking.bsky.social. Very excited to make this #bigdata 🔢📈 project a reality.

Oceans are "seanonymous" with life 🌊 Vast and deep, they cover most of our planet—holding 97% of its water. They nourish us, shape and regulate our climate, and produce over half of the oxygen we breathe.

Tag, we’re it!🎣 Inspired by @AquaticTracking.bsky.social we took a closer look at how the FACT Network contributes to tracking species at risk of extinction. Within the FACT Network, researchers have tagged 140 different species and 43% of them are at risk of extinction. ⬇️

That's where the magic of ETN network comes in!🪄 Sharing data on the ETN database enables us to perform Europe-wide telemetry meta-analysis & the freshly published article on the seaward spawning migration by European eels, from Verhelst et al.(2025) is the perfect example! doi.org/10.1111/faf....

Happy #WorldBiodiversityDay! 🎣 To celebrate, we dove into 2024 data - 60 fish species across 36 families were tagged & uploaded to the ETN database! 🐟🦈 These animals will help reveal migration & habitat patterns across Europe & beyond🌍 📊 Swipe to see what’s hiding in “other” 👀 #trackingnotslacking

DID SOMEONE SAY CRAB?? 🦀 That's right, the ETN community is tracking more than just fish! Check out the recent article in Movement Ecology about the seaward migration of invasive Chinese mitten crabs. 🎉 Read the paper here: tinyurl.com/36py5z5v 📷: Heleen Keirsebelik

#BaskingSharks of the #ArticCircle 📢Tracking the second largest #fish for a full year, our new paper invites you on a deep #dive into the life of a cold water giant between the Barents Sea and the Azores 🐟❄️🌊🏝️🇳🇴 #sharkscience #IMR @forskning.no @aquatictracking.bsky.social 🧵 1/4 🚨 rdcu.be/elqvS

It’s World Endangered Species Day! 🐟 Both plant & animal life face numerous threats that have led to population declines and even extinction. In aquatic environments, these risks usually include overfishing, habitat degradation, pollution, coastal urban development and climate change...

HUGE NEWS! 😍 The UN Decade of Ocean Science has endorsed our new DTOTrack project! 🌊 DTOTrack will map movements and distributions of marine life in the North Sea & use this data as an Essential Ocean Variable to create a digital twin of the area 🐟 europeantrackingnetwork.org/en/undos #OceanDecade

Happy #WorldTunaDay! 🐟 Tunas are a group of 15 species of sizes from under 50 cm in length and around 7 kg in weight to "astunamical" (🙃) sizes of around 3 meters and almost half a ton. ⚖️ Let’s celebrate these fantastic animals today (and tunaight)! 📷: AdobeStock

Daylight Saving Time has arrived and we wonder—do fish risk arriving late at the offish the day after advancing clocks? ⏰ Just like we all know some who are early birds and others that are night owls, fish, too have their own early risers and late sleepers 💤

Five categories of human stressors (including nonnative species introductions) have eroded global biodiversity and reshaped the biosphere.

We ( @drcatmac.bsky.social and I) are writing a marine conservation science and policy textbook! We'd love to include case studies of ocean conservation success stories, and we welcome submissions of ideas here: docs.google.com/forms/d/e/1F... Please be clear and detailed! 🧪🦑🌎🐟

Always a pleasure to go diving in the cold but vibrant waters of Galicia‼️ 🦈🐟🐙

MYSTERY UNCOVERED ✨ Acoustic telemetry has uncovered an important reproducing site for gilthead seabreams 🐟 in the Parc National des Calanques on the French Mediterranean coast! This work highlights the regional importance of that zone for the species. #CONNECTMED www.youtube.com/watch?v=y1F0...

🌊 Ocean sunfish on the move! 🌊 The ocean sunfish (Mola mola) is among the largest and most mysterious bony fish, which is why researchers tagged 23 juveniles in Portugal, Spain and northern Africa with long-term acoustic transmitters (lasting over 7 years!) to track their movements.📡 1/5
