Thousands of tons of dead sardines wash ashore in northern Japan
The sardines and some mackerel washed ashore in Hakodate on Japan’s northernmost main island of Hokkaido on Thursday morning, creating a sliver blanket along a stretch of beach about a kilometer (0.6 mile) long. Takashi Fujioka, a Hakodate Fisheries Research Institute said the fish may have been chased by larger fish, become exhausted due to a lack of oxygen while moving in a densely packed school, and were washed up by the waves.

Sea Lice Outbreak Claims At Least 1 Million Salmon in Tálknafjörður

Scientists observe chum salmon spawning in North Slope rivers
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.

Drought in B.C. has salmon running 'a marathon in a sauna,' foundation warns
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.

Coastal Rivers Lacking Steelhead
After the January storms provided the flushing and scouring our coastal rivers desperately needed, anglers were thinking and hoping the winter steelhead would be there. Up and down the coast, well known steelhead rivers are not seeing the numbers we're accustomed to. This same scenario happened a couple years ago, but the fish finally showed up. And that will more than likely be the case again this year. But with the calendar now saying February, it's getting a little more nerve racking.

Lack of rainfall cause for up to three weeks of delay for salmon spawning this season
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.”

NOAA trawl survey: Cold pool returns in the Bering Sea

Salmon struggle to spawn amid record-setting drought

Fish die off near Kotzebue
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.

After decades of dwindling runs, sockeye salmon return to Yukon fishing village in droves
