With climate change, as many as 25 new species may enter the Barents Sea by 2025.
"New species are coming, others are being squeezed into the border zones," said Maria Fossheim of Europe's Institute of Marine Research.
It is still difficult to predict which species will be more common in the Barents Sea by that date, however, polar cod is an example of a species that is likely to be squeezed out, Fossheim said.
