Skildring:
Lovely fieldwork in Matre Research Station last week for CRIMAC project. Some net pens with salmon are now equipped like RV G.O.Sars, that is with full research vessel worth of scientific echosounders (the orange thingies). Five Simrad EK80 scientific echosounders (That is a lot!). These will observe salmon in 3 net pens for 5 weeks for individual swimming behavior and acoustic echo properties while fish swimbladder is slowly shrinking in volume.
