Mowi Canada East reports 166,262 farmed salmon died at two sites near Chaleur Bay on Newfoundland’s south coast, blaming repeated sea lice infestations intensified by warm surface waters, low freshwater runoff, and calm winds. The incident follows earlier 2025 mass mortalities linked to a thermocline inversion and warm, low-oxygen conditions.

Dozens of dead tomcod have washed up on West Beach in Nome, Alaska, with a possible link to recent sightings of beluga pods, raising concerns about unusual environmental conditions.

Calm late-summer conditions and a fall surge in forage fish activity led to a rare sighting of harbor porpoises inside Maquoit Bay in Brunswick, Maine. The columnist reflects on seasonal transitions and why porpoises may have ventured into the typically shallow bay.

A fisherman from Qasigiannguit, Greenland, unexpectedly found a rare porbeagle shark entangled in his salmon net near the abandoned settlement Akulliit. The shark measured about 2.35 meters and was estimated over 200 kg—an unusual catch in Greenlandic waters.

About 3.5 million liters of livestock-based biomanure leaked from Havila Biogass in Molde, spreading from a marsh into waterways and a small-boat harbor, causing fish and crab deaths. Norway’s Coastal Administration called it one of the largest such spills they’ve encountered and will order cleanup; the company is conducting remediation and investigating a failed pipe gasket as the likely cause.

A provincewide drought in Nova Scotia has dried up brooks and streams, stranding trout and white suckers and stressing native fish, while a woods ban limits access to assess impacts. Warmer water favors invasive chain pickerel, and restoration work is paused; Atlantic salmon migration is also being blocked by low flows.

Alaska health officials issued an alert after wild shellfish from Kachemak Bay’s inner bay tested above regulatory limits for paralytic shellfish poisoning toxins. Residents are warned not to harvest or eat untested wild shellfish; monitoring and test results are being posted by the Alaska Harmful Algal Bloom Network.
