Norway Redfish

Sebastes norvegicus

Sighting evidence at Svolvær Wall, Lofoten Islands

Norway redfish are long-lived, slow-growing rockfish that gather along Svolvær Wall in groups of five to twenty individuals, hovering in mid-water beside the anemone-encrusted rock as though suspended. They are exceptionally slow to mature — females do not breed until they are around 12 years old — and can live for over 75 years in Norwegian waters, making even modestly sized individuals likely older than the divers observing them. Their vivid red-orange coloration fades to grey at depth where red wavelengths are absorbed, but in torch light they blaze with colour.

How is this calculated?

Sighting evidence is compiled from iNaturalist observation records within a set proximity radius, filtered for quality-grade observations. “Last confirmed” is the date of the most recent research-grade record. Record count covers a rolling 24-month window. Confidence reflects record count, recency, and consistency of seasonal signal.
