A new plant species is establishing itself in the area and impacting native beach greens.
"Grayling guts with unknown pearl like cyst or tapeworm. Never seen this before in our grayling."
With a bleak salmon return this year in Northwest Alaska, a lifelong fisherman reflects on a season marked by empty nets and big questions.
An unprecedented outbreak of sea lice in Tálknafjörður has led to the loss, or the need to dispose of, at least one million salmon. “Nobody has seen anything like this before. There is a Norwegian veterinarian who has been working in Iceland because of this and he has never seen anything like this in his 30-year career,” Karl Steinar observed.
Erratic temperatures led to the absence of tomcods, severely affecting local fishing.
Invasive elodea decade history in the Chena slough with mitigation and persistent infestation.
Scientists from the University of Alaska Fairbanks have observed an increase in chum salmon spawning in North Slope rivers, potentially indicating a shift in their population and a signal of climate change. Elizabeth Lindley, a Ph.D. student working on the project, says that while evidence of spawning in a new region may be a positive for salmon, the impact on important subsistence resources including Arctic char and Dolly Varden is uncertain.
The Lower Elwha Klallam Tribe catches coho salmon on the free-flowing Elwha River for the first time in over a century since the removal of dams, marking a historic moment for the tribe and the river's recovery.
Nearly a million dead fish, including redfish and menhaden, washed ashore in southwest Louisiana due to commercial fishing boats dumping an estimated 850,000 fish from their overfilled nets, sparking calls for stricter limits on the state's commercial menhaden fishery.
Jackie Hildering was astonished by a recent photo depicting an enormous Mola mola submitted to the Marine Education Resource Society citizen science project, which is collecting data on two different species of sunfish along the Pacific Coast.
British Columbia's prolonged drought risks damaging the salmon population for generations and has led to a series of emergency, rapidly deployed projects in an effort to intervene. In the Comox Valley, aerators have been installed in the Tsolum River to maximize salmon survival by increasing dissolved oxygen levels, and work has started at the mouth of the Tranquille River to re-establish water flow between the upper and lower sections so salmon can migrate upstream to their spawning grounds. More than 80 per cent of the province is at Level 4 or 5 drought conditions, the highest possible rankings, after months of little or no rain.
In early October Vancouver Island reached a drought Level 4 which impacted wildlife across the coast. After a mass salmon die off in Bella Bella, concern grew regarding drought and a delayed salmon spawning season. Currently east Vancouver Island is at a drought level of 3, which means adverse impacts are possible, while west Vancouver Island is at a drought level of 2 with less likely impacts. Dave Rolson, Tseshaht First Nation’s fisheries manager, said, “Timing is everything, really, when it comes to fish and when it comes to environmental conditions.”
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.
The Mola tecta, a semi-tropical sunfish, had been misidentified until seven years ago and is rarely seen in the northern hemisphere.
Record-setting drought conditions have left many of B.C’s streams and waterways too low for salmon to swim up to spawn. Heiltsuk First Nation leaders say hundreds of fish were found rotting in a creek in Bella Bella, B.C., usually teeming by fall with migrating pink and chum salmon.
Ali Ralson was riding her 4 Wheeler towards Cape Blossom and came upon a beach full of fish. It appears that most of the fish are stickleback although there may be other species involved too. This would suggest an environmental issue that would impact multiple fish species rather than a pathogen. One potential cause could be harmful algal toxins.
In a recent report from the Icelandic Food and Veterinary Authority (MAST), 16 salmon caught in the Mjólká river in the Westfjords were confirmed to originate from farms. Signs indicate that the salmon originate from open sea farms by Haganes, where a hole in the pen caused part of the stock to escape in August.
Scientists from B.C.’s provincial government are investigating a spike in dead sturgeons after 11 adult fish were found dead on the Nechako River over the past week.
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.
The Icelandic Food and Veterinary Authority (MAST) has found evidence of infectious salmon anaemia (ISA) in an open-net salmon farm in Reyðarfjörður fjord, East Iceland. ISA is a highly infectious viral disease that has no treatment and causes high mortality in farmed Atlantic salmon.
