Chum salmon spawning in the Arctic may provide food for native fish species, helping them survive in the biologically unproductive waters, as scientists study the changing ecology of the region due to warming temperatures.

Scientists from the University of Alaska Fairbanks have observed an increase in chum salmon spawning in North Slope rivers, potentially indicating a shift in their population and a signal of climate change. Elizabeth Lindley, a Ph.D. student working on the project, says that while evidence of spawning in a new region may be a positive for salmon, the impact on important subsistence resources including Arctic char and Dolly Varden is uncertain.

The Barents area is the fastest warming place on the planet. A new study shows that the warming is happening twice as fast as previously thought.

Approximately 87,000 farmed cod escaped from Gadus Group's aquaculture facility, raising concerns about potential impacts on wild fish populations and prompting investigations into the incident.

Warming waters have driven thousands of ocean species poleward from the equator, threatening marine ecosystems and the livelihoods of people who depend on them.

Arctic cod are a cornerstone of the Arctic food chain as a staple food of seals and beluga whales, upon which subsistence food gatherers rely in the region’s coastal communities.
