Responses in spatial distribution of Barents Sea capelin to changes in stock size, ocean temperature and ice cover
Using data for the period 1972–2010, we relate the variations in the Barents Sea capelin distribution to stock size, ocean temperatures and the area available for dispersal during summer. We find a strong relation between distribution area and stock size, which is most likely caused by a large stock...
