The extensive spawning migration of Northeast Arctic cod was suggested to be counterbalanced by increased early-offspring survival, however we find in a study published in July in Marine Ecology Progress Series, that early offspring growth should be considered as another factor explaining this long-distance migration.

We assessed the effect of the predator−prey relationship on predator survival by developing a novel metric of predator−prey overlap using spatio-temporal statistical models. We found that the amount of overlap between cod larvae (length: 11−15 mm) and their prey explained 29 % of cod recruitment variability.

The year 2014 marks the 100th anniversary of the Norwegian oceanographer and biologist Johan Hjort’s ground-breaking work, Fluctuations in the great fisheries of northern Europe, viewed in the light of biological research. This anniversary was commemorated with a special issue of ICES Journal of Marine Science.
