Should I stay or should I go (home)?

21 September 2021. The team is investigating the homing ability of the goldsinny wrasse, a territorial reef fish that performs relatively short winter migrations from shallow to deeper water. In September, a team from IMR (Kim Halvorsen, Torkel Larsen, Even Moland and Esben Moland Olsen) and the University of Agder (Lars Korslund) surgically implanted telemetry tags in 60 goldsinny wrasse. …

Assessing the effects of offshore wind turbine facilities on fish early life stages

June 2021 – This has been an intense period for Alessandro Cresci, who has been conducting field work using a unique combination of intruments to assess if/how the operational noise generated by offshore wind turbines affects the swiming and orientation behaviour of fish larvae. Alessandro places fish larvae into drifting chambers and, using a Geospectrum Technologies C-Bass speaker, simultaneously plays …

Field work for offshore wind project ++ kicks off!

7 May 2021 – Studying the orientation behavior of cod, haddock and halibut larvae in situ in Norwegian fjords (using drifting chambers) to support a better understanding, and biophysical coupled simulation modelling, of their dispersal. For cod, haddock, and sandeel, we will also obtain unique data to better understand the possible impact-risk (if any) of planned large-scale offshore wind facilities …

Hunting for sand eel

Mid-december 2020 – A team from IMR consisting of Caroline Durif, Alessandro Cresci and Elin Sørhus went out to the open ocean outside of Karmøy to fetch ripe sandeel. Together with fisherman Geir Kenneth Eriksen and his boat “Åkrabuen”, they caught 45 adult sand eel and brought them back to the IMR’s Austevoll Research Station. Sand eel is a forage …

The eel field work period has started!

28 July 2020 – Eel season has started and our team is collecting samples to learn more about the life history strategies of the European eel. Eels are catadromous, meaning that they spawn in the sea but grow in freshwater. However, some individuals skip the freshwater phase and complete their life-cycle in marine coastal waters. During our current field work, …
