red and blue swirls on map

Rapid deoxygenation in the Gulf of St. Lawrence is caused by shifts in two of the ocean’s most powerful currents: the Gulf Stream and the Labrador Current. A detailed model shows that large-scale climate change is causing oxygen to drop in the deeper parts of this biologically rich waterway.

Key ocean fish can prevail with changes to farmed fish, livestock diets

forage fish swimming

Anchovies, herring, sardines and other forage fish play an essential role in the food web as prey for seabirds, marine mammals and larger fish like salmon. When ground into fishmeal and oil, they are also a key food source for farmed seafood and land-based livestock such as pigs and poultry. As seafood consumption outpaces the…
