The school of fish - Photo: Ingolf Kristiansen
Ingolf Kristiansen was out for a walk with Anton, his miniature schnauzer, when he came across the school of saithe, a type of fish belonging to the cod family, frozen beneath the ice.
"I've never seen anything like it. It has not happened before here as far as I know," he told NRK. "A temperature of minus 7.8 degrees, combined with an east wind, made the bay freeze in a very short time. The saithe had been chased to the shore by cormorants, and apparently were not able to get out to the open sea again."
Kristiansen has been deluged with calls from the international media since the photo was first posted up on NRK's website on Monday.
"Even my son got lots of calls," he told NRK. "Last night, when my son went to bed, he had 14 messages on his voicemail. It's really fun that so many people have read it, but my son was frustrated at having a mobile registered to his father yesterday."
