Migration behaviour of Norwegian spring spawning herring when entering the cold front in the Norwegian Sea
The distribution of Norwegian spring spawning herring when migrating to the feeding areas in the Norwegian Sea in spring has been mapped by surveys in April1995 and 1996. The schooling behaviour of the herring have been recorded by a high resolution sonar, and the swimming speed and swimming directi...
