The cause of death is almost certainly acute Aspergillosis, a respiratory tract infection caused by a fungus commonly found in soil, dead leaves, moldy grain, compost piles, or in other decaying vegetation. Wildlife managers say the die-off seems to have stopped, likely due to the fungus source no longer being available.

Homalco First Nation to push for special hatchery permits

The warmest November in over 100 years has had unusual consequences in Finnmark. The video shows the third breakup this autumn.

For the first time, cod and squid have been found deep in the water at the center of the ocean. The research by Pauline Snoeijs Leijonmalm, a professor at Stockholm University, was part of the Mosaic expedition, an icebreaker that spent a year trapped in the Arctic's ice.

Southeast’s total salmon harvest was 19 million fewer fish than last year. There was a drop in harvest for every species except chinook, which increased by a few thousand fish.

A mass die off of fish and invertebrates has been reported in the Sea of Okhotsk, west of Kamchatka. Dozens of surfers reported symptoms including including poor eyesight, fever, diarrhea, nausea, vomiting, skin rashes and head and throat aches.

This year the Eagle station's fall chum estimate is 23,828 fish. This is far below the escapement goal of 70,000 to 104,000 fish.

The number of salmon returning to Chester Creek has improved since 2008. This year, spawning salmon are lingering in the creek later than usual.

Khalaktyrsky Beach near Petropavlovsk is littered with hundreds of dead sea animals, from deep-sea Giant Pacific octopuses, to seals, sea urchins, stars, crabs and fish. Surfers were the first to raise alarm after problems with eyesight, fevers and throat aches.

A rare deep-sea fish was discovered on Vancouver Island this month. A pair of friends, Natalie Mueller and Andie Lafrentz, were walking along Whiffin Spit in Sooke on Sept. 19 when they spotted what they first thought was a “large piece of scrap metal.”

It was a king-of-the-salmon (Trachipterus altivelis), a deep-sea-dwelling species of ribbonfish. Its common name comes from the legends of the Makah people west of Strait of Juan de Fuca, which believe this “king” leads the salmon to their spawning grounds each year.

The Yukon First Nations Education Directorate gave away 30,000 pounds of free fish as part of its nutritional program in Whitehorse this week. People were particularly happy to receive the donation because salmon are well below the historical average this year.

A lack of chum salmon is causing pain in riverside communities of Yukon and Alaska, as mushers are left without a traditional source of food.

So far, the department has counted just under 37,000 fish at the Chilkat weir, well below the 10-year average of 80,000 fish. Zeiser said at this point in the season, it’s doubtful the run will hit the escapement range of 70,000 to 150,000 fish.

About 189,000 fall chum had entered the Yukon River as of Sept. 7. At least 300,000 fish must enter the river before either Alaska or Yukon fishers can begin harvesting.

After learning about catches of pink salmon near Salluit, Quebec wildlife officials are urging any fishers who net the newcomers to report their catch. Two pink salmon were netted in Nunavik during the summer of 2019 in the Ungava Bay region, one near Kangirsuk.

Dead or dying eggs in a female coho salmon are a possible symptom of environmental stress felt by the fish. In Western Alaska, water levels have been low following a rapid spring snowmelt and low precipitation.

Residents note significant changes in the Christiansen Lake ecosystem since 2019. This includes fewer nesting birds, fish, and mammals around the lake, while the leech population has increased along with the occurrence of algal blooms.

Slimy sculpins (Cottus cognatus) are small, nocturnal, bottom-dwelling fish that lack a swim bladder to help them stay bouyant in the water. Their size and habitat allow them to easily avoid fishing gear designed for salmon.

Early snowmelt and low precipitation have led to low river water levels on the southern Seward Peninsula. Low water levels may be a contributing factor in observations of poor fishing, and poor fish health, along the western coast of Alaska.
