These worms, present in halibut, cod, salmon and other saltwater fish, are increasing. If the worms are well frozen or cooked, they don’t pose a health threat.

In Taloyoak, Nunavut, Inuit leaders are working to establish an Inuit Protected and Conserved Area (IPCA) to safeguard their culturally significant lands and build a sustainable, community-driven economy. The initiative highlights the community’s determination to protect traditional food sources and cultural practices in the face of potential industrial development.

This summer, NOAA and the International Whaling Commission will conduct aerial and ship-based surveys in the eastern Bering Sea to monitor beluga and large baleen whale populations, employing new methods and expanding survey areas based on previous findings.

Japan plans to expand its commercial whaling to include fin whales, five years after resuming whaling and leaving the IWC.

A right-wing leader advocates for increased whale hunting and international marketing of whale meat, despite global regulations and declining participation in the industry.

The article discusses concerns over the impact of human-made noise on endangered Cook Inlet belugas and the debate over noise mitigation measures.

Scientists are investigating the widespread presence of paralytic shellfish toxins in Alaska's marine food chain, which may explain recent species die-offs.

“It’s a reflection of the plastic age we live in," said student researcher Tony Blade. "It’s ubiquitous."

A study by the Alaska Environment Research and Policy Center found microplastics in all water samples from Southcentral Alaska, indicating widespread contamination.

The new children's book combines traditional knowledge and scientific research to tell the story of a ringed seal pup in Kotzebue, Alaska, with a focus on the impact of climate change.

A study reveals that increased ship noise in the Arctic disrupts the behavior and communication of marine mammals, impacting local wildlife and indigenous hunting practices.

Health officials in Sanikiluaq, Hudson Bay, warn against consuming fermented meat due to a suspected botulism outbreak and urge vigilance for related symptoms.

Steller sea lions are the most affected by human activities in Alaska, leading to hundreds of deaths, primarily due to entanglement in fishing gear.

Wolves in Katmai, Alaska, have been observed hunting sea otters and seals, suggesting a significant ecological link between land and marine life.

Over 5,000 Peruvian sea lions, approximately 5% of Peru's population, succumbed to a mass mortality event linked to the avian influenza A(H5N1) virus, signaling an urgent need for research and conservation efforts to prevent further declines. The rapid spread of the virus among these colonially breeding mammals highlights potential risks of cross-species transmission and the necessity for heightened monitoring to avert new pandemics.

A new AI radar system called "Bear-dar" has been developed to detect polar bears remotely and send alerts to notify people of their presence, and could potentially be used to detect grizzly and black bears as well, helping humans and bears coexist safely.

Toxicological studies spotlight the effects of pollutants on polar bears and whales, with new research strategies being developed to understand their impact on marine life.

The North Atlantic right whale population in Canada has stabilized, with no reported deaths since 2019, but there are still concerns about entanglements and low birth rates.

New research off Cape Breton reveals that female pilot whales are the most frequent leaders during dives, often leading from the left or right flank, which could provide insights into mass strandings and help guide whales out of stranding situations more efficiently.

Most of the humpbacks were seen near the Inupiat village of Point Hope, indicating a feeding hotspot in that area. While sightings farther north have been less numerous, there has still been an increase in recent years. The study suggests that climate change and the reduction of Arctic sea ice may be a factor in the expansion of humpback whale range.
