Anglers fear up to 46,000 fish dead after 'devastating' kill on Blackwater in Co Cork
A large fish kill on a 30 km stretch of the River Blackwater in north County Cork has reportedly killed thousands of fish; Inland Fisheries Ireland estimates 8,000–10,000 wild fish, while local angling groups put mortality as high as 46,000. Preliminary sampling indicates fungal infection on many fish, but no evidence to date links the kill to a licensed discharge.

The first case of a walrus dying of bird flu registered on Svalbard
“Last year we got several reports from tourists and scientists that they saw around six walruses dead here on the west side of Svalbard. Unfortunately, we couldn’t sample them as the dead walruses drifted away by the time we got to the place. But it’s not normal to get so many reported dead walruses in such a small area," said Christian Lydersen, senior scientist at the Norwegian Polar Institute. Now samples (collected by a Station Manager in July 2023) have tested positive for highly pathogenic avian influenza.

Fears of bird flu in colony on Hornøya in Finnmark with critically endangered seabird

There are also reports of sick gulls and sea eagles along the entire coast up to East Finnmark.

"Since about May 25, crews have been seeing multiple species showing what we believe are signs of highly pathogenic avian influenza. The signs we are seeing widespread is a headshaking that we equate to "getting the cobwebs out", like a person may do when they first wake up. This behavior occurs regularly every couple minutes. This behavior has been observed in: black brant, cackling geese, bar-tailed godwits, dunlin, lapland longspurs, spectacled eiders, emperor geese, greater white-fronted geese, sabines gulls, glaucous gulls, and red-necked phalaropes."
