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
