Does anyone in my telemetry network have hands‑on experience tagging Black rockcod, Marbled rockcod, Blackfin icefish, or related species? I’m looking for practical tips and lessons learned — especially regarding anesthesia protocols @aquatictracking.bsky.social @oceantracking.bsky.social

Last week, Mikkel Emil and I attended the fish telemetry conference in Traverse, Michigan. Despite various challenges, partly arising from the new U.S. administration, the conference was very well executed, with excellent and insightful presentations. A great thanks to the committee of #ICFT2025

På oppdrag for Nye Veier har vi gjort en kartlegging av effekter fra støy fra påleboring på fisken i Mjøsa gemini.no/2025/04/stoy...

Støy stresser fisk, de svakeste kan dø
Fisk reagerer ulikt på støy. Noen arter svømmer kjapt unna, men kommer snart tilbake. Svake individ kan dø.

A fishy day at #UNIS for the limnology class. Guest teacher @grimsruddavidsen.bsky.social taught about ecology and behavior of #Arctic_charr. Fascinating how this 🐟 species coop with living in the #Arctic. Students got hands-on experience with modern fish tracking equipment. @limnology.bsky.social

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
