With temperature warming, fish population are not only changing their foraging zone but also where they are spawning their eggs. While temperature can be beneficial for high latitude species it may also lead to some constraints. In their paper, Langangen et al (2025) studied the effect of changing spawning location for Atlantic cod in the Barents Sea.

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.
