A big one

NINA has many gigabytes of videos from the Riverwatchers at Storsjødammen, Høyegga, Strandfossen and Løpet fish-ways but this is one is the favorite so far at least! By using the Riverwatcher from VAKI the fish can swim freely through the scanner where they get measured without traps and being handled.
