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
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.

Salmon struggle to spawn amid record-setting drought
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.

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
The number of sockeye returning to Klukshu, Yukon, to spawn began to drop off in the 1990s. This year, hundreds of the bright red fish line the small creek that winds through the village. Neither the Champagne and Aishihik First Nations nor Fisheries and Oceans Canada are sure why the fish have returned after decades of steady decline.

Coastal fishermen report dramatically smaller herring catches in the Baltic Sea
Fishermen fishing close to the shore in the Baltic Sea have seen a steady decline in herring and Baltic herring catches over many years. Large-scale trawling further out at sea could be one of the reasons behind it.

What's a shark ordinarily associated with the Arctic doing in Belize?
A half-blind shark that is typically thought to live in freezing Arctic waters, scavenge on polar bear carcasses and survive for hundreds of years, recently turned up in perhaps an unexpected place—a coral reef off Belize. This marks the first time a shark of its kind has been found in western Caribbean waters off the world's second longest barrier reef.
