dc.description.abstract | The migration routes of Norwegian spring spawning herring have changed
considerably during the last decades. In the 1950s and beginning of
the 1960s the stock spawned off the west coast of Norway in late
winter, were distributed in the feeding season in the Iceland-Jan
Mayen area, and wintered east of Iceland. In the mid 1960s a large
part of the stock wintered and spawned of northern Norway and were
distributed in the northern part of the Norwegian sea during the
feeding season. The stock collapsed in the late 1960s, and during the
rebuildning period the stock wintered in different fjords on
the Norwegian coast, spawned at Møre and were located in near coastal
waters of Norway in the feeding season. However, from 1988 when the
strong 1983 year class recruited to the spawning stock a new change in
the migration pattern was observed. At present the stock spawns at
several locations along the Norwegian coast, including the traditional
spawning grounds at Karmøy in south-western Norway where spawning was
resumed in 1989. In the feeding season the herring is distributed
over large areas in the Norwegian Sea. In late July and August the
herring migrates eastwards, and in September enters the wintering
areas in northern Norway. | no_NO |
