Representatives from several Indigenous-led organizations discussed co-management strategies at the Alaska Federation of Natives convention panel.

Researchers have relocated 20 Atlantic catfish to artificial kelp forest units in Melkøy Sound, Northern Norway, to test if reintroducing sea urchin predators can help restore kelp forests overgrazed by booming sea urchin populations.

Shrimp biomass in Greenland has declined significantly over the past two years, prompting major fishing companies and the fisheries organization QAK to call for industry adaptations.

Alaska DEC tests of mussels from Kachemak Bay found no domoic acid toxin associated with amnesic shellfish poisoning, though mussels can quickly expel the toxin so its presence in other species remains uncertain.

Sitka had an early bloom that led to high shellfish toxins in April, and there is currently a paralytic shellfish toxin advisory across Southeast for recreational and subsistence harvest.

The Knik Tribe's monitoring program for paralytic shellfish poisoning was paused in April as the federal government investigates its legitimacy for funding.

Despite reduced overall ice coverage in Canada's Northwest Passage, the Arctic shipping season is shortening due to increased mobility and breakage of sea ice creating navigational hazards.

New data reveals high salinity levels in several Halifax lakes, posing a threat to aquatic life. Halifax considers new measures to manage salt runoff.

“Fishing has been very good for the [Bristol Bay red king crab] fleet this season and the crab delivered so far has been of high quality — new shell, large size, good meat-fill,” said Alaska Department of Fish and Game Area Management Biologist Ethan Nichols.

A severe storm in Kotzebue, Alaska, caused significant flooding, displacing 80 people and damaging critical infrastructure, including roads and the airport.

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.

The unusually hot summer weather in the Moscow region this year may trigger an increase in populations of invertebrate species, the regional Environmental Ministry said this week.

ADF&G has confirmed the spread of the invasive European green crab in Alaska, urging increased monitoring and public awareness to mitigate its destructive impact on local ecosystems.

Adult abundance “well below” fishery thresholds on both beaches. This outcome was not unanticipated, as the department said when opening the fishery in Ninilchik last year that adult abundance met necessary thresholds for allowing harvest — at least meeting or exceeding 50% of the historical average — but juvenile abundance was low, meaning there would likely not be enough adult clams this year or next.

Applications for relief funds from Alaska's 2019 and 2020 crab fisheries disasters are now open, with $13 million allocated for the Bering Sea Tanner crab fishery.

Invasive species like green crabs and choke cherry trees are causing environmental and economic harm in Alaska.

While blue mussels are a traditional source of subsistence food in Unalaska, in recent years, reduced numbers and concerns about paralytic shellfish poisoning, or PSP, have limited the amount locals can safely harvest.

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

Knik Tribe data reveals high levels of paralytic shellfish poisoning toxin in some Alaskan subsistence shellfish harvests, with variability in toxin levels across different locations.

The Okanagan Basin Water Board is proposing a temporary ban on out-of-province boats entering British Columbia's waterways to prevent the introduction of invasive mussels that could cause significant harm to the ecosystem and cost the province millions of dollars annually.
