Three new evolutionary ecology PhD positions are open in Switzerland (Eawag, and Uni. Bern) to work on Greenland lake ecosystems. We are interested in how stickleback and copepods evolve, and how their evolution affects the trajectories of lake ecosystem development. apply.refline.ch/673277/1403/...

Applications are open for NoWPaS 2027! If you are a grad student or postdoc studying anadromous salmonids, apply to join us in Scotland this February! Application and more info: nowpas.wordpress.com

7,000 years before farming reached Scandinavia, hunter-gatherers carried live trout past waterfalls to stock fishless mountain lakes. Newly dated fish traps at Lake Tesse, Norway show planned ecosystem management long before agriculture. 🐟🏔️🦴 #Archaeology #Mesolithic @antiquity.ac.uk

There's something fishy going on in the frigid, dark depths of Lake Superior. Scientists have discovered a growing number of emaciated lake trout deep in Lake Superior, about half their normal body weight, dubbing them "zombie fish." They’re racing to learn what’s behind the phenomenon.

🐟🌡️🧪 New study from #ThermoEvo project @luke.fi: Juvenile Atlantic salmon show no increase in aerobic scope during an ecologically realistic #heatwave. This suggests limited capacity to cope with higher oxygen demand in warming rivers, when O2 costs increase. onlinelibrary.wiley.com/doi/10.1111/...

🐟 CALL FOR ABSTRACTS OPEN for #NoWPaS2026! 📍 Hólar University, Iceland 🇮🇸 📅 March 2–7, 2026 🧑‍🔬 For early career researchers on anadromous salmonids 🗓️ Deadline: Nov 10, 2025 👉 forms.gle/unryb2EZEcp1... ℹ️ nowpas.wordpress.com Join us in Iceland for science, salmonids, and connections!

#JFB: Spatial ecology and population dynamics of brown trout 𝘚𝘢𝘭𝘮𝘰 𝘵𝘳𝘶𝘵𝘵𝘢 L. in reservoirs and headwater tributaries doi.org/10.1111/jfb.15814 #FishSci

2 results, and 3 speculations from this paper: academic.oup.com/jeb/advance-... Results: (1) Greenlandic stickleback co-occurring with Arctic char are bigger and (2) have relatively smaller heads than when stickleback are alone in a lake.

Excited that the latest work from my PhD is available as a pre-print! (doi.org/10.1101/2025...) We explore the challenges in delineating conservation units within highly diverse species using the salmonid species Arctic charr as a study system!

Will you help us save #ArcticCharr from extinction in the #LakeDistrict? Our campaign to raise funds for the Lake District Charr Recovery & Management (LD-CHARM) project has just launched! From 22-29 April your donations will be doubled! Find out more & donate: donate.biggive.org/campaign/a05...

Super happy to see our new article on how pharmaceutical pollution can influence salmon migration out in @science.org! This was a huge effort by a great team of researchers over the last few years! You can read the paper here: science.org/doi/10.1126/sc…!

We are looking for a post doc (2 year position) to work on fundamental and applied salmonid migration ecology. Work place is Eawag in Kastanienbaum, Switzerland, located on the shores of Lake Lucerne. See more here: apply.refline.ch/673277/1241/...

When baby salmon emerge from the gravel, how far do they disperse to summer rearing grounds? We haven't known until now (at least at the population scale), because they're too small to tag. In a paper just out, we answered this question using parentage-based (genetic) tagging! tinyurl.com/39b2sfjd

Trout will eat shrews when available (sometimes gorging on them) & are not affected by their venom or objectionable taste.

Atlantic #salmon, brown #trout and their hybrids can be difficult to distinguish, especially at early life stages. This new DNA-based method can be used to screen lots of individuals to verify the species or detect hybrids! 🧪🐟 With a low-cost DNA extraction, it is less than 1 euro / sample.

Angling creates hook shy pike, our latest paper finds. onlinelibrary.wiley.com/doi/full/10....

Paper alert: We used acoustic telemetry combined with stable isotope analyses in a southwest Greenland fjord to investigate marine migrations, thermal habitat use, and marine feeding habits of Arctic charr cdnsciencepub.com/doi/pdf/10.1... @oceantracking.bsky.social @aquatictracking.bsky.social

Now for some good news: "Seven decades after overfishing and invasive species nearly wiped them off the map, Lake Superior’s lake trout population has finally recovered." via @bridgemichigan.bsky.social www.bridgemi.com/michigan-env...
