Test results show the bloom was almost certainly to blame for mass deaths of kina as well as crayfish, starfish and sea cucumber which washed ashore at Hardinge Rd, including Sandy Beach, and on a small part of Westshore Beach eight days ago.
Just over a year ago, the Alaska Department of Fish and Game applied the pesticide rotenone to two lakes and a stream in the remote Miller Creek drainage on the northern Kenai Peninsula to eradicate the last known population of invasive northern pike on the Kenai Peninsula.
The Bering Sea’s cold pool, a critical part of the seafloor ecosystem, had shrunk to a worrying degree in recent years, but it is continuing to slowly return, according to the latest results of NOAA’s bottom trawl survey. Saffron cod, also called tomcod, seems to be bouncing back after a few bad years, and Arctic cod and blue king crab numbers were also better.
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.
James Power doesn’t have a final tally yet on how much post tropical storm Fiona cost Raspberry Point Oysters Ltd., but the damages are likely to be in the ...
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.
The European Green Crab are a threat to ecosystems and commercial fisheries. They uproot eelgrass beds in search of food, which serve as habitat for herring and salmon.
One UBC scientist says his early estimation that a billion creatures died from the 2021 heat dome was too low. Today, life is returning to areas scorched by last year’s unprecedented heat wave. The die off was patchy and the plants and animals in the intertidal zone that survived the heat wave “are the parents to the next generation,” Harley said.
"The event occurred on June 29th, on our native allotment near Kotzebue (Illivak). We left home in the morning and when we came back around 8:00 PM in the evening the whole lake had drained! It looked like it was blown up with dynamite."
When he checked closer, he found that the snail he found was an Arctic shrub, or Dendronotus robustus. All of the previous sightings have been made on Svalbard, so this may be the first confirmed find in mainland Norway.
Historically cold temperatures made it difficult for invasive species survive in Alaska. The Japanese skeleton shrimp Caprella mutica is now established in Unalaska area and in this observation observed on a buoy line in Nateekin Bay.
Observations this year from Huu-ay-aht territory see that volume of herring may finally be improving, as the First Nation is reporting a growing number of wild salmon migrating through its rivers.
