Migration behaviour of herring along the cold front in the Norwegian Sea in April 1997
The behaviour of Norwegian spring spawning herring when migrating to the feeding areas in the Norwegian Sea in April was mapped by an acoustic survey in 1997. The distribution of herring was recorded by conventional echo integration, and the swimming behaviour of selected herring schools was recorde...
