Observations

Mystery invertebrate in a red crab
A crab was caught on the ice just offshore in Nome. It had a small invertebrate in the gills of the crab.
Nome, Alaska, United States

Absence of Tomcods
Erratic temperatures led to the absence of tomcods, severely affecting local fishing.

Red or Black Currants?
Red and Black Currants are present on the property and the moose seem to be picky about what berry they like to consume.
Anchorage, Alaska, United States

Something is eating salmonberry leaves
"This season we have observed many salmonberry bushes that appear to be defoliated. It seems something is eating the leaves. We have also noticed the berries look sickly."

Tapioca disease in pink salmon
White cysts in the muscle of salmon could be caused by Henneguya salminicola also called "tapioca disease". It affects the texture of the meat but is not a health concerns for people. White cysts could also however, be from a tape worm. That is a human health concern. Guidance on how to check the cysts to confirm and how to prepare food so it is safe to eat, is provided.

Smaller salmon and slower returns
The sockeye salmon are coming back smaller for the Newhalen River and Iliamna Lake, plus not a thick as they once did when I was younger.
Newhalen, Alaska, United States

Insect on cloud berries
Is the abundance of insects unusual? Updates from around the state with picking and weather impacts.
Trapper Creek, Alaska, United States

Swollen limb in caribou
An image of a swollen leg on this caribou raises questions that it may be a case of brucellosis.

Minke whale pod sighted
A rare sighting is possible indicator of prey abundance.
Kasaan, Alaska, United States

No sea ice in Grantley Harbor
December should have sea ice development in Norton Sound. But no sign of ice yet this year. Several storms have moved northward across the western Bering Sea and brought strong winds and bouts of above freezing weather to the Teller area and all of the Bering Strait region.

Lots of dead krill washed up on Sarichef Island
Die-offs of krill are in some cases associated with hypoxia (low oxygen) excess sediment suspended in the water column and changes in water temperature. There were recent reports of high levels of Alexandrium in water samples in the areas, and Norton Sound Health Corporation is performing some testing of krill samples (see below). There was also an unprecedented storm event only a week ago, unusual for the storm surge and early season.

Storm bounty in clams
Storms can bring a bounty to the beach - driftwood sometimes or in this case, clams! But be careful out there. There are new concerns about emerging levels of harmful algae in Western Alaska waters, which could impact shellfish and human health.

Salmon run disrupted by trench dug across Coquihala River
There were alternatives for Trans Mountain Corporation to digging a trench in the river to lay pipe during the time the salmon were running.
Hope, British Columbia, Canada

Infestation of caterpillars
A resident of Seldovia reported an infestation of worms infesting an area of salmonberry brush and nettle.
Seldovia Village, Alaska, United States

Spittle bug widespread in Clare, Ireland
I saw an extreme amount of spittle bugs not only on grasses and plants but on flowers.
Liscannor, Munster, Ireland

Stickleback fish die-off
There were a plenty of what appeared to be juvenile dead stickle back fish on the top of the embankment of a few ponds.

Unusual bird behavior and illness observed across species on Yukon Delta
"Since about May 25, crews have been seeing multiple species showing what we believe are signs of highly pathogenic avian influenza. The signs we are seeing widespread is a headshaking that we equate to "getting the cobwebs out", like a person may do when they first wake up. This behavior occurs regularly every couple minutes. This behavior has been observed in: black brant, cackling geese, bar-tailed godwits, dunlin, lapland longspurs, spectacled eiders, emperor geese, greater white-fronted geese, sabines gulls, glaucous gulls, and red-necked phalaropes."

Growing cases of bird illness in Norton Sound
Over the past five days there have been increasing reports of unusual behavior in a variety of bird species including brant goose, snow goose, white-fronted goose, and Canada goose.

Where are the tomcods (Eleginus gracilis)? Kongiganak
The tomcod harvests in the Kongiganak, Cavuuneq and Ilkivik Rivers have been a failure. Also in other areas, based on observations from Chevak and Chefornak. Both the surface and bottom trawl results show a clear decline in tomcod biomass in the North Bering Sea.

Where are tomcods / Naugat Ceturr'nat (Eleginus gracilis)? Chefornak
Not a single catch was reported in the village of Chefornak. Meanwhile in Kivalina, dozens and dozens of tomcods are pictured and posted on "The Alaska Life" Facebook page.
Chefornak, Alaska, United States

Where are the tomcods (Eleginus gracilis)? Chevak
There is usually an abundance of this fish in the fall and early winter season. This is a usual harvest for most YK Delta coastal villages. Note: According to NOAA Bering Sea Bottom Trawl data, there has been an 88% decline reported in the biomass of saffron cod from 2020 to 2021 in the N. Bering Sea.

High water this summer changes travel on Noatak River
"This year we had a lot more rain than other years, we used to be able to get on our ATVs and travel 10-12 miles upriver. I haven't seen or heard of anyone using ATVs to travel upriver this year. I think the breakthrough channel has a lot to do with us not being able to travel on ATVs. I see a lot of my favorite ATV fishing spots washed away from the highwater."
Noatak, Alaska, United States

Decrease in Prawn Abundance of Desolation Sound
It is apparent that this area of coastline has experienced a sharp decline in its prawn populations. This may be due to increased fishing pressure from commercial prawn fishermen.

Insect eating red currant leaves
Red currant leaf consumption by something was observed by my supervisor while walking along a salmon stream.
Lazy Mountain, Alaska, United States

Sea Life Die-Off Found on Beach
"While on a field trip for work, we stopped at the beach and you can notice hundreds of dead clams and star fish littering the beach."

Decline in and delayed salmon on the Skeena River
In recent years, we have observed the salmon arriving at our territory along the Skeena River later than normal and in fewer numbers. The total number of wild sockeye (Oncorhynchus nerka) returning to the Skeena River have decreased by 69% in comparison to historical stocks.
