Cod, herring could pass through Northeast Passage in future

In future, an ice-free Northeast Passage will allow, among other things, cod, herring and blue whiting from the Atlantic to migrate into the Pacific—while other species can move in the opposite direction, according to a study by DTU Aqua researchers.
The study shows that many of the investigated 515 fish species have the potential to move north as temperatures rise. When the sea ice recedes, and there is food to be found in the previously inhospitable Northeast and Northwest Passages, the fish will be able to move here and, with time, spread into new waters.
It applies, for example, to the traditional Danish New Year cod, or Atlantic cod, which is one of the top-ten commercial fish species, and which researchers expect will inhabitate the Northwest and Northeast Passages by 2100. Here, the cod will provide the basis for a completely new fishery.
