Abstract while a few north atlantic cod stocks are stable, none have increased and many have declined in recent years although overfishing is the main cause of most observed declines, this study shows that in some regions, climate by its influence on plankton may exert a strong control on cod stocks, complicating the management of this species that often assumes a constant carrying capacity.
