Weโ€™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!

Out in the Lilleร… 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

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

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 (ร˜resund) between Denmark and Sweden. Data will be uploaded into the European tracking network database.

โš ๏ธโš ๏ธ 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 ๐Ÿ‘‡
