No abstracts are to be cited without prior reference to the author.There is a high certainty that global warming is a reality. Future climate change scenarios from Global Circulation Models indicate a rise in temperature and a decline in sea-ice coverage in the Barents Sea. Coupled biological-physical models project an increase in the plankton production as a response to climate change in the area. Model studies also show that a higher primary production tends to lead to an increase in cod recruitment in the Barents Sea. This together with the expected acceleration of growth and maturation rates will lead to an increase in cod stock productivity as response to the warming. On the other hand model analyses demonstrated that cod predation in the Barents Sea ecosystem, including cannibalism, would grow due to increment in rations, as water temperature will rise. In this regard, a question of how future management of cod may have to be adapted to account for climate change impacts is of interest. Simulation ...
